Mei Lanfang’s swimsuit photos taken during her stay in the United States.

　　　　Mei Lanfang improved the hairstyle and clothing of the new fashion drama, and added fashion elements to the Beijing drama.

　　　　For the modern young audience, Mei Lanfang is just a symbol. From the textbook, we know that he is the first of the four famous artists and represents the culture of Peking Opera. Perhaps many people can’t tell the difference between Mei Lanfang and Anita Mui. In fact, Mei Lanfang is not only a master of art, but also the most popular fashion star of the year. Recently, some netizens exposed a group of unknown old photos of the Peking Opera master in real life in the forum. In this group of photos, a rare photo of Mei Lanfang wearing a swimsuit is particularly eye-catching.

　　Mei Lanfang loves fashion to take swimsuit photos.

　　　　The netizen said that this swimsuit photo was taken in Shanghai in the 1930s, when the social atmosphere was not so open. On the other hand, the shooting background seemed to be out of place with the word swimsuit. However, some netizens said that in Shanghai in the 1930s, fashionable people would take a few swimsuit photos. At that time, people often saw the appearance of swimsuits from those fashionable cigarette cases and moon cards. As a well-known Peking Opera actor at that time, Mei Lanfang was naturally unwilling to lag behind, and generously took such a swimsuit photo by the swimming pool.

　　　　According to the historical records of that year, in 1926, the public swimming pool in Hongkou, Shanghai was opened to the public, and men and women traveled together in Shanghai. By 1930, Gao Qiao Beach had been built, and swimsuits had long been the equipment of Shanghai-style figures. At that time, almost all the stars and celebrities-Shang Guanyunzhu, Ruan Lingyu, etc.-had fashionable styles in swimsuits. Mei Lanfang’s swimsuit photo was produced under such an "open" historical background, even though it was not taken in Shanghai but in the United States on the other side of the ocean. In 1946, when Drama Illustrated published this swimsuit photo of Mei Lanfang during her stay in the United States, it also caused quite a stir.

　　Love to take pictures, generous show camera

　　　　Mei Lanfang’s hobby of spare time also keeps ahead of the trend. In old Shanghai, it was fashionable to take photos in a photo studio, not to mention owning a camera. Cameras were a luxury at that time, and families who could buy them must be rich and fashionable enough. Mr. Mei Lanfang’s camera, which seems to be inadvertently painted, is also put into the photo to some extent as an ornament that embodies a kind of taste and shows off.

　　Singing Beijing Opera in Modern Costume

　　　　Besides taking photos, Mr Mei Lanfang used fashionable elements in Beijing Opera, and he was once called the "originator of fashion dramas in Beijing Opera". At that time, he personally created a new play "The Waves of the Evil Sea", and at the same time he created his own hairstyle and clothes for the new fashion play, which was true to others. It is understood that Mei Lanfang rehearsed three new fashion plays, among which "Deng Xiagu" and "A wisp of hemp" received great response. For a time, Peking Opera dressed in modern clothes became fashionable, and it did not lag behind the vernacular drama at that time.

　　How far is it from playing mobile phone every day to illness? Recently, a reporter from qianjiang evening news learned from the hospital that there is a 30-year-old clerk in Hangzhou who deals with computers, keyboards and mice every day, and likes to play with mobile phones during the spare time. As a result, his hands are numb enough to require surgery. Psychologists also warned mobile phone owners that if they keep looking at their mobile phones while shopping, they will spend more money. If you let your mobile phone sleep with you, it will do more harm to your health.

　　Keyboard and mobile phone play too much.

　　In addition to hand numbness, muscle atrophy will occur.

　　Zhou Qi (a pseudonym), 30, keeps her hands on the keyboard at work and keeps brushing her mobile phone at rest. She also has a habit of sleeping on her desk with her hands on her pillow during lunch break. It seems that most people’s living habits have damaged her ulnar nerve. It shows that the right hand is numb and tingling, and it takes a long time to straighten your arm to recover. Even the buttons are awkward, and you can’t even carry chopsticks when eating … … After a series of examinations such as electromyography, Zhou Qi was diagnosed as "cubital tunnel syndrome".

　　The ulnar nerve in medicine is what we usually call "numbness". It is one of the three main meridians on the arm. It starts from the cervical vertebra, passes through the elbow joint, sticks to the inside of the arm and goes down all the way to our ring finger and little finger. It is of great significance to our daily life, and the fine movements of our fingers, such as buttoning, holding chopsticks and holding a pen, can not be achieved without the contribution of ulnar nerve.

　　Frequent elbow flexion and other actions will cause ulnar nerve compression, leading to "cubital tunnel syndrome", which will affect the function of fingers and palms. When the sensory function of ulnar nerve is affected, there will be symptoms of numbness of fingers or palms, and when its motor function is also affected, there will be phenomena such as weakness of fingers or muscles. If it is affected for a long time, it will easily cause muscle atrophy and even cause serious irreversible consequences.

　　Use the keyboard and mouse for a long time, bend your elbows for a long time, or sleep on your desk, etc. Some people have cubital tunnel syndrome due to playing mahjong for several days, and office workers and surgeons are all high-risk groups. In order to completely cure the symptoms, Zhou Qi had to undergo surgery.

　　The doctor reminded that to prevent such diseases, one is: rest.

　　If you repeat an activity, whether it is typing, using the mouse or anything else, it is recommended to take a short break every 10 to 15 minutes to rest your elbow and wrist. During this period, you can stretch and exercise these two parts.

　　Second, keep a good working posture.

　　Adjust the height of the seat to keep the forearm as high as the keyboard. When using the keyboard, there should be no feeling of outward expansion and drooping, so that the elbows and wrists are in a relatively relaxed state.

　　The third is: always be vigilant. Once there is numbness and discomfort in the finger, and it is a constant and persistent feeling, you must not ignore it easily. You should go to the hospital as soon as possible for professional judgment and exclusion.

　　Play mobile phone while walking.

　　Shopping is more expensive.

　　A new study by American scientists shows that if you play with your mobile phone while shopping, it will not only increase the risk of hitting obstacles, but also make people spend a lot of money unconsciously.

　　The research team of Fairfield University asked 231 participants to complete a simulated shopping task. One group of participants restrained themselves from taking out their mobile phones and only paid attention to the goods, while the other group randomly used their mobile phones intermittently for unrelated tasks (such as answering phones, sending and receiving text messages, listening to music, etc.). Both groups of participants used to shop according to a shopping list provided by the researchers, but the results showed that people who used their mobile phones occasionally or constantly in the store made far more unplanned purchases than those who concentrated on shopping.

　　The researchers pointed out that when shopping, people may forget what goods they need most when they are distracted, but they will be attracted by the dazzling array of other goods in the store and take them into their pockets without thinking. Even if you only use your mobile phone occasionally during shopping, it will have this effect, which will lead to additional expenses. Therefore, we should concentrate on saving money when shopping.

　　Wang Yiquan, an expert in early intervention of psychological problems in Hangzhou No.7 Hospital, said: "From the perspective of behavior patterns, those who rely heavily on mobile phones have poor self-control ability, and they are easily influenced by external information such as price reduction and new product listing when shopping, resulting in more impulsive consumption. From the analysis of emotional influence, the information from the mobile phone will affect the mood of shoppers, and these emotions may stimulate impulsive consumption whether positive or negative. Seeing good news, buy something to reward yourself or your family; When you see bad news, you should buy something to comfort yourself and decompress. For example, people often joke that ‘ Bao ’ Treating all diseases is the most vivid explanation of the influence of emotions on shopping. "

　　We have to admit that consumption is indeed a good way to vent and quickly adjust emotions, but only if it is moderate. If it is inappropriate or even unreasonable consumption beyond one’s own ability to pay, one must be alert to whether there are psychological problems.

　　In fact, in life, it is easy to understand the difference between men and women’s shopping habits. For most men, shopping is a kind of "torture". They often think about where to buy something, go straight to the destination and buy it, and then leave. They rarely pay attention to what other stores are selling along the way, and naturally they will not have unplanned consumption. Women tend to take shopping as a kind of "leisure", walk around, shop around, stop and watch more, and the temptation is more likely to lead to many unplanned consumption.

　　Sleeping with your mobile phone is harmful to your eyes.

　　Playing mobile phone for a long time at night often leads to sore eyes, sharp drop in vision, deepening myopia, and even dry eye. Once, because of playing mobile phone games for a long time, the function of meibomian gland was worse than that of the elderly.

　　Everyone’s two eyes have a dominant eye and a non-dominant eye. Under normal circumstances, under the control of the brain, the eyes of both eyes are even, but after lying on the side, one eye has to shoulder a heavier eye task. Over time, if the balance is broken, the vision will be inconsistent between the left and right eyes.

　　Sleeping with mobile phone is harmful to cervical health

　　"Cervical arch inversion" is the most common pathological basis of cervical diseases. High pillow can make the head bend forward and increase the stress of the lower cervical vertebra, which may accelerate the degeneration of cervical vertebra. However, bad living habits such as lying on a high back and watching TV, surfing the Internet for a long time, lying down and playing with a mobile phone, and pulling the cervical vertebra for a long time will also lead to the curve lordosis decreasing, straightening and even bending back.

　　Sleeping with mobile phone affects sleep quality.

　　Adequate sleep is a necessary guarantee for a healthy life. When playing mobile phone, the production of melatonin (secreted by pituitary gland, which directly affects the quality of sleep) will be reduced, which will lead to less sleep and even inability to sleep. I believe those who play mobile phones until midnight or even later have a profound experience — — I’m not sleepy at all. I don’t want to sleep.

　　Sleeping with mobile phones affects family harmony.

　　Young people, once they have cell phone sleepiness, are not in a hurry to find a partner. They think that cell phones are so fun and have everything in them. Why do they need to find a partner? Parents look at the older single children, but they really hate the dead mobile phone. After three days, they cursed, "I know how to play mobile phones every day, and others have grandchildren, so you will give me a mobile phone?"

Recently, a touching love relay was staged on a street in Lishui, Zhejiang. Passers-by stopped one after another, picked up brushes and pigments, and used colors and creativity to revitalize the original monotonous blind road …

The sponsor of the activity is called Fang Cunxin. She is a painting blogger and an optimistic one-armed girl. "When I went out once, I met a blind man who wanted to cross the road. Because the blind road is occupied, I can only accompany the blind man for a while. " Fang Cunxin was deeply surprised by this experience. In the city where she lived for many years, blind people were rarely seen.

This incident prompted her to pay attention to the blind road construction in the city. "Many blind roads are occupied and destroyed by bicycles, and even the colors of many blind roads are dim and almost unnoticed." As a painting lover, Fang Cunxin had an idea, "If passers-by are allowed to leave their own works of art on the blind road, can it arouse everyone’s attention to this’ forgotten corner’?"

After obtaining the approval of the relevant departments, she opened the event with acrylic paint and brushes.

Passers-by spontaneously participate in activities and paint on the ground. Photo courtesy of respondents

On the first day of painting, Fang Cunxin still needs to shout at the roadside, hoping to attract more passers-by to participate. On the second and third days, hundreds of people have spontaneously joined this street public welfare activity. "At first, I only planned to draw 50 meters, but when I came to my senses, this road has extended far and far." Talking about the scene where everyone actively participated in the activities, Fang Cunxin was very emotional.

"Although they can’t see, we can use this tangible color to pave an invisible road for them. I can keep painting because it is a very meaningful thing. " A girl who participated in painting at the scene squatted at the intersection for several days and created on the ground one by one.

Hundreds of passers-by participated in the painting of "Rainbow Road". Photo courtesy of respondents

Everyone calls this road "Rainbow Road". As Fang Cunxin said, "I hope this rainbow road will be infinitely extended in our hearts, maybe the color will fade, but love will continue!" From one person to a group of people and then to everyone, strangers pick up brushes. In this way, they contribute to the better integration of disabled people into society.

Twenty-three departments jointly issued nineteen measures.
Accelerate the release of demand and expand residents’ consumption

With the consent of the State Council, 23 departments, including the National Development and Reform Commission, the Publicity Department of the Communist Party of China and the Ministry of Finance, jointly issued the Implementation Opinions on Promoting Consumption Expansion, Upgrading and Accelerating the Formation of a Strong Domestic Market (hereinafter referred to as the Opinions). The Opinions put forward 19 measures to promote consumption expansion and quality improvement from six aspects: market supply, consumption upgrading, consumption network, consumption ecology, consumption capacity and consumption environment, and help form a strong domestic market.

Expanding consumption is an important focus to hedge the impact of the epidemic.

The COVID-19 epidemic has had an impact on China’s consumption at present and even in the future, especially in the fields of shopping, catering, tourism, culture, education and entertainment.

"Releasing the suppressed and frozen consumer demand, cultivating and growing the new consumption and upgraded consumption that were born in the prevention and control of the epidemic, and making the physical consumption and service consumption be replenished, is one of the important points to hedge the impact of the epidemic." Chang Tiewei, deputy director of the Employment Income Distribution and Consumption Department of the National Development and Reform Commission, said that it is of great significance to promote consumption expansion and quality improvement while doing a good job in epidemic prevention and control.

Since last year, the CPC Central Committee and the State Council have deployed a series of policies to promote consumption, and various localities have successively introduced a number of targeted measures, such as Beijing, Tianjin, Shanghai and other places to build a new platform for consumption upgrading by cultivating night economy.

"The Opinions are the inheritance and development of previous policies." Chang Tiewei said that it not only inherited the previous policy orientations such as updating consumption and cultural tourism consumption, but also integrated into the new models, new formats and new industries in the current new consumption development.

To expand consumption, the key is to conform to the upgrading trend of residents’ consumption, break through the "blocking point" and "pain point" in the consumption field, break down the institutional and institutional obstacles that restrict consumption, and improve the governance capacity in the consumption field. The "Opinions" adhere to the structural reform of the supply side as the main line, seize the most potential consumption areas and focus on improving supply, constantly improve consumption policies, optimize the consumption environment, and stabilize consumption expectations.

Chang Tiewei introduced that the Opinions pay more attention to service consumption in terms of consumption types; Highlight holiday and night consumption in terms of consumption time; Accelerate the cultivation of new models such as online and offline integration in terms of consumption patterns; Focus on launching the county consumption engine in the consumption area; In terms of consumer groups, we will focus on enhancing the consumption power of low-and middle-income groups, and urge the vast number of urban and rural residents to consume, be willing to consume, and dare to consume.

Accelerate the construction of information infrastructure and build a "smart+"consumption ecosystem.

Cloud fitness, cloud shopping, cloud shopping, cloud reading … Since the outbreak, "cloud business" has developed rapidly. "Mobile phone ordering and delivery to home" has become the first choice for people to buy fresh food, medicines and other necessities during their stay at home.

"The new consumption formats and new models represented by online shopping have shown strong development potential in this epidemic." Chang Tiewei said that in 2019, the online retail sales of physical goods in China accounted for 20.70% of the total retail sales of consumer goods, which was about 8.52 trillion yuan. It is expected that the online retail sales of physical goods will exceed 10 trillion yuan this year.

"With the gradual control of the epidemic, China’s consumer market will usher in a new round of rapid development opportunities." Wei Wang, director of the Institute of Market Economy of the State Council Development Research Center, said that innovative online service models, especially in the fields of entertainment, education and medical care, have been recognized and accepted by consumers, which will greatly promote the further improvement of new formats and new models and drive more online service consumption.

The "Opinions" put forward four specific measures to cultivate new consumption formats and new models, and accelerate the construction of a "smart+"consumption ecosystem.

Accelerate the construction of a new generation of information infrastructure. Accelerate the construction and commercialization of information infrastructure such as 5G networks.

Encourage the development of new consumption patterns such as online and offline integration. Improve the "internet plus" consumption ecosystem, and promote online and offline interaction and business travel style coordination.

Encourage consumers to use green smart products. Encourage enterprises to use the Internet of Things, cloud computing, artificial intelligence and other technologies to promote the intelligent upgrade of various electronic products, and accelerate the development of new information products such as virtual reality and wearable devices.

Vigorously develop the consumption pattern of "internet plus Social Service". All departments will promote the online and offline integration of education and training, medical care, aged care services, infant care, sports events and other service consumption.

"The Opinions proposes to build a’ smart+’consumption ecosystem to adapt to the development trend of smart and online consumption at this stage. While promoting consumption expansion and quality improvement, we will better lead the industry to intelligent and green development and promote the dual upgrading of industry and consumption. " Wang Yun, a researcher at China Macroeconomic Research Institute, said.

Continuously improve consumption capacity and build a consumption network integrating urban and rural areas.

The consumption pattern is wired online and offline, and there are cities and towns in the consumption space. To improve the quality and expand the consumption, it is necessary to realize the coordinated and interactive development of the urban and rural markets. What other "hard bones" are there to break through urban and rural consumption and expand grassroots and rural consumption?

"There is still a’ stuck neck’ link in the current consumer infrastructure." Chang Tiewei said, for example, the service consumption infrastructure is not perfect, the shortcomings of consumption facilities in some emerging urban areas and rural areas are prominent, and the distribution of urban commercial facilities is unreasonable.

Wei Wang said that in order to build a consumption network integrating urban and rural areas, on the one hand, we should promote the construction and development of consumption center cities, accelerate the development of middle and high-end consumption and service consumption markets, and form a group of international consumption center cities with large consumption scale, strong consumption radiation driving effect, outstanding consumption innovation leading ability and international influence, and become a leading demonstration base for China’s consumption upgrading and expansion.

The "Opinions" propose to further improve the tax-free industry policy and improve the supply of imported goods. We will support central cities to strengthen the "first-store economy" and "first-time economy", encourage internationally renowned brands to launch or simultaneously list new products in the China market, and adjust and optimize the collection links of some consumption tax items.

"On the other hand, we should speed up the sinking of the consumer market, build a platform for cooperation and exchange between Internet companies and poverty-stricken areas, promote the two-way circulation of industrial products to the countryside and agricultural products to the city, boost the sales of agricultural products with characteristics and advantages in rural areas, especially in deep poverty-stricken areas, and better meet the consumer demand in rural markets and carry out consumption poverty alleviation in depth." Wei Wang said.

The income level of residents is directly related to their consumption ability, and the expansion and upgrading of consumption cannot be separated from the improvement of consumption ability.

"To improve the consumption power of residents, we should pay attention to improving the income capacity of middle-income groups and enhancing basic security, and promote the reform of the income distribution system." Wei Wang said, smooth the upward flow channels for low-income groups, steadily expand middle-income groups, strive to narrow the income gap among residents, and accelerate the improvement of the income incentive mechanism for knowledge-based, skilled and innovative workers.

The century puzzle left by Einstein and Bohr to future generations

In the early days of the establishment of quantum mechanics, the phenomenon of "entanglement" aroused the curiosity of all physicists, and Einstein called it "strange interaction between distant places."The so-called entanglement in quantum mechanics is a phenomenon: two particles in an entangled state can maintain a special correlation state, and the state of both particles is unknown, but as long as one particle is measured, the state of the other particle can be known immediately, even if they are far apart.. In the past half century, the essence behind this phenomenon has been deeply puzzling scientists.

In the last century, the views on entanglement divided physicists into two factions: the Copenhagen school, represented by Bohr, believed that the so-called "reality" was meaningful only when it was connected with observation methods; But scientists such as Einstein can’t accept this view. They think that quantum mechanics is incomplete, and the measurement result must be predetermined by some kind of "hidden variable", but we can’t detect it. In 1935, Einstein, Podolsky and Rosen published an article entitled Can Quantum Mechanics Description of Physical Reality Be Considered Complete, demonstrating the incompleteness of quantum mechanics. Usually, people call their argument EPR Paradox or Einstein Localized Realism.

Bohr and Einstein argued about this for 50 years, and the problem was not solved until their final death, which has always attracted future generations to verify it.

How to verify it?

mentionLocalized realismIn fact, it contains two meanings:First, physical realism.Any observable physical quantity must exist objectively in a definite way, and if there is no external disturbance, the observable physical quantity should have a definite value;Second, localized causality.If the four-dimensional space-time between two events is space-like, there is no causal relationship between the two events. Based on this understanding, in 1964, the Irish physicist Bell put forward the famous "Bell Inequality", which established a strict limit on the possible correlation degree of the results when two separated particles were measured at the same time [1]. If Bell inequality is not established in the experiment, it means that the expectation based on localized realism does not conform to the theory of quantum mechanics, that is,The quantum world itself is probabilistic.

All along, people have designed various experimental schemes to verify whether Bell’s inequality is correct or not, and one after another, the results of some experimental groups tend to support the destruction of Bell’s inequality-that is, to prove the correctness of quantum mechanics. The first truly definitive experiment was made by Spector, a French physicist. Three experiments they made in the 1970s gave a clear conclusion about the nonlocality of quantum mechanics, but there were still loopholes in the initial verification of these experiments. In recent years, experimental groups in different countries have tried to gradually close local vulnerabilities, free choice vulnerabilities and detection efficiency vulnerabilities in their experiments.All the experimental results support the conclusion of quantum mechanics and prove that localized realism is wrong.

Bell inequality goes out of the laboratory and flies further.

The destruction of Bell inequality has been verified in the laboratory, so what about the situation on a larger scale? If people can verify the existence of quantum entanglement at a longer distance, it means verifying the correctness of quantum mechanics at a larger spatial scale. Therefore, people want to fly farther with Bell inequality. However, there is a stumbling block-attenuation when conducting experiments on a larger scale. What does this mean? In the actual experimentPeople often use an experiment called "quantum entanglement distribution" to verify Bell inequality, which is to send two prepared entangled particles (usually photons) to two points far apart, and to verify whether quantum mechanics and localized realism are right or wrong by observing whether the measurement results of the two points conform to Bell inequality.Because pairs of single photons are prepared and sent, the signal of single photon is not amplified because of the non-replicability of quantum, and the inherent photon loss of optical fiber makes it difficult to expand the optical quantum transmission to a longer distance. On the surface of the earth, the quantum entanglement distribution of 100 kilometers is almost the limit.

What should we do? There are two schemes,One is to use quantum relay.One relay station is a bit like an ancient relay station, transmitting photons one by one, but at present, the research of quantum relay is still limited by the time and efficiency of quantum storage;Another scheme is to realize quantum entanglement distribution by satellite.The vacuum environment in outer space has almost no attenuation and decoherence effects on light transmission. The free space channel loss between the satellite and the earth is small, and even in theory, scientists can establish a quantum channel between any two points on the earth by using satellites, and it is possible to realize quantum entanglement distribution at a long distance on a global scale.

On December 9, 2016, at the Ali Observatory in Tibet, researchers were doing experiments.

Fortunately, in this respect, Chinese is at the forefront of the world.

As early as 2003, China’s Pan Jianwei team put forward a scheme to realize long-distance quantum entanglement distribution by satellite, and started preliminary verification. The team’s researchers believe that in order to prove that it is feasible for satellites to realize quantum entanglement distribution, it is necessary to prove that photons can remain coherent after penetrating the atmosphere, so they began to do experiments in Dashu Mountain, Hefei. In this experiment, the sender is in Dashu Mountain, and the two receiving points are in Feixi farmer’s home and the west campus of Chinese University of Science and Technology, which are several kilometers away. It is the first time in the world to realize the two-way quantum entanglement distribution in free space with a horizontal distance of 13 kilometers (the vertical thickness of the atmosphere is about 5-10 kilometers), which proves that the entangled state can still "survive" after long-distance atmospheric channel transmission. On the other hand, this transmission distance exceeds the equivalent thickness of the atmosphere, which proves the feasibility of long-distance free space quantum communication.

Two-way quantum entanglement distribution in free space with a horizontal distance of 13 kilometers in 2005

In 2010, the team realized the 16 km quantum teleportation based on quantum entanglement distribution for the first time in the world. Based on the preliminary key technical preparations, at the end of 2011, the strategic pilot science and technology project "Quantum Science Experimental Satellite" of Chinese Academy of Sciences was formally established. In 2012, the joint research team of Chinese Academy of Sciences led by Pan Jianwei realized the first quantum entanglement distribution experiment of more than 102km in Qinghai Lake. In the experiment, the maximum attenuation is 80dB. On the one hand, it is verified that the entanglement characteristics still survive through the atmospheric channel on a larger scale, on the other hand, it is verified that the entanglement characteristics can be maintained under the condition of very large attenuation, which further verifies the feasibility of satellite-ground entanglement distribution.

In the following years, the team worked hard to overcome various difficulties and finally developed the "Mozi" quantum science experimental satellite. In the eyes of hundreds of millions of people, the Mozi was successfully put into orbit on August 16, 2016. After four months of on-orbit testing, it was officially delivered to carry out scientific experiments on January 18, 2017.

Mozi quantum science experimental satellite

As one of the three scientific experimental tasks of Mozi satellite, satellite-ground quantum entanglement distribution is the first quantum entanglement distribution experiment on the spatial scale in the world.

There are three optical payloads on the Mozi quantum science experimental satellite. Pairs of entangled photons are prepared by the quantum entangled light source and sent by two optical antennas. When the satellite transits the border, two telescopes point to Delingha and Lijiang ground stations respectively. The receiving systems of the two ground stations, according to the angular velocity of the satellite, make the satellite establish quantum channels with the two ground stations at the same time and send entangled photons to the ground stations.Then the ground station carries out entanglement measurement of photons, and if there are enough statistics, the Bell inequality can be verified.

In this experiment, the distance between the two ground stations is 1200 kilometers, the total distance from the satellite to the two ground stations is 2000 kilometers on average, the tracking accuracy of the ground station reaches 0.4 urad, and the receiving efficiency of the ground station system is more than 20%. The entanglement source on the satellite can generate 8 million entangled photon pairs per second, and the establishment of optical link can establish quantum entanglement between two stations over 1200 kilometers on the ground at the speed of 1 pair per second, so that a large number of statistical data can be obtained in a short time. If photons are transmitted by optical fiber over such a long distance, even if ultra-low loss optical fiber is selected, it will take 30 thousand years to distribute a pair of photons.

In the experiment, the two photons are pulled apart by a large enough distance, and at the same time, the high-precision experimental technology ensures that the independent measurement time interval between the two places is small enough, which meets the measurement requirements of "space-like interval" in Bell inequality measurement and closes the localization vulnerability and measurement selection vulnerability.The experimental results show that the standard deviation of 4 times violates Bell inequality, that is, the correctness of quantum mechanics is verified at a distance of thousands of kilometers with a confidence of over 99.9%.The nonlocality test of quantum mechanics which strictly satisfies Einstein’s localization condition is realized. This important achievement has laid a reliable technical foundation for the future experimental study of large-scale quantum networks and quantum communication, as well as the experimental examination of the basic principles of physics such as general relativity and quantum gravity in outer space.

Related achievements were published in the international authoritative academic journal Science in the form of cover papers.. In addition to the quantum entanglement distribution experiment, other important scientific experimental tasks of Mozi quantum science experimental satellite, including high-speed satellite-ground quantum key distribution, satellite-ground quantum teleportation and so on, are also under intense and smooth progress. It is expected that more scientific achievements will be released to the public one after another this year.

On November 28, 2016, at the Xinglong Observatory in Hebei Province, the "Mozi" quantum science experimental satellite transited.

Note:

[1]Bell inequality has many famous generalizations. Considering the practical factors of the experiment, five years after Bell inequality was put forward, John Clauser, Michael Horne, Abner Shimony and Richard A. Holt put forward a CHSH inequality, and the experiment of Bell inequality in later experiments was mainly to verify CHSH inequality.

[2] Space-like separation means that the space-time interval of two events satisfies that "it is impossible to communicate between two events with information below the speed of light.

　　On November 1st, the international version of Xingtu officially ushered in the market, and the price range of the new car was 228,900-238,900 yuan, with three versions. The new car will continue to be equipped with a 2.0T engine +8AT transmission, with a maximum torque of 400 N m.. Today, we will test drive this model and feel what upgrades and changes have been made in the international version of Starway Moon.

　　In terms of appearance, Starway Moon International Edition still adopts the family-style design style, but it has changed in some details. The biggest change is the use of a brand-new octagonal air intake grille with horizontal decorative strips, which looks domineering enough.

　　The light group adopts a penetrating design. When the lights are turned on at night, the middle light band will be lit. The position of the eyebrows of the headlights uses a blackened design, which also reflects the personalization of the car. In addition, chrome-plated decorative strips are added to the air inlets on both sides of the front bumper, which adds a lot of fashion to the car.

　　The shape change of the side of the car body is not great, and the through waistline design is still used, and the traditional door handle shape is retained, so the use convenience is still very high. In terms of body size, the length, width and height of the new car are 4970x1940x1792mm and the wheelbase is 2900mm respectively.

　　The shape of the rear end of the international version of Starway Moon Tour has not changed much, and the design of the through taillight group is still retained, which effectively increases the layering of the rear end. The rear bumper is decorated with a chrome trim strip, and equipped with a double exhaust layout, and the vertical reflectors on both sides are also preserved.

　　There is no change in the design of the interior, mainly reflected in some details, such as the addition of all-black color matching, which also provides consumers with more choices. In addition, the dual wireless charging panel of the new car is also decorated with suede, and the maximum power can reach 50W.

　　Although it is a fuel SUV, the car uses a two-spoke steering wheel, with bronze decoration and multi-function touch panel, as well as a panel with a sense of space, which enhances the luxury of the whole interior. Shift paddles are also reserved on the steering wheel, which can effectively improve the driving pleasure of the vehicle.

　　The international version of "Journey to the Moon" retains the penetrating triple screen design, and the 12.3-inch LCD instrument panel can display a lot of driving information of vehicles, including speed, driving mode, speed, entertainment information, navigation information, cruising range, etc., and the display clarity is still very high.

　　HUD head-up display is also very easy to use. When navigation is not turned on, HUD can display information such as vehicle speed and rotation speed. When navigation is turned on, HUD can display navigation information, including text and dynamic images, with good clarity.

　　Lion5.0 lion system will be used in the central control screen. The UI design of the whole screen is very user-friendly, and the delamination application is in place. The commonly used functions can be found at the bottom of the screen. The screen can support online navigation, online entertainment, mobile phone interconnection, voice interaction, OTA upgrade and other functions, which can fully meet our daily use.

　　The intelligent driving system of the new car can also be selected and set on the screen, and the whole interface is easy to understand. In addition, the air conditioning, seats and other functions of the vehicle are also placed on the screen, which can be controlled by voice or from the screen, and the sense of technology is still very high.

　　The sliding cover is still reserved in the central channel. After opening, the wireless charging panel of the mobile phone below is made of suede, which looks more advanced and feels very good. The maximum power of the wireless charging panel of the mobile phone is 50W, and a cooling vent is designed at the lower position, so that the mobile phone will not generate heat even if it is charged for a long time.

　　A small touch panel is also designed in the rear position. Here, it integrates the control of one-button start of the vehicle, double flashing, air conditioning air volume adjustment, defogging of front and rear windows, internal and external circulation, etc. It needs to be familiar with it for the first time, but the overall luxury temperament is still very good.

　　The car we test-drive today is a 6-seat model of the international version of Starway Moon. The seat configuration of the car is also rich enough. The front seats are not only equipped with electric adjustment, but also have functions such as seat heating, ventilation, memory and massage. At the same time, there are speakers in the headrest, which is more clear and specific when playing music or broadcasting road conditions.

　　The second row uses two separate seats, which are also electrically adjustable. Although the distance of the slide rail is not very long, it can also meet the riding needs of passengers in the second row or even the third row. The comfort of the second row of seats is also relatively high, and even if you ride for a long time, you won’t feel tired.

　　The third row of seats also uses two independent seats, the softness of the seat cushion is also very good, not as thin as expected, and the head and leg space is acceptable. The backrest is also designed with 5/5 points, all of which are manually adjusted, and the support of the backrest is average.

　　There is no change in the power of the international version of the Star Way Lunar Rover, and it is still consistent with the current models on sale. It uses a 2.0T engine with a maximum power of 261 HP and a maximum torque of 400N·m, which is matched with an 8AT transmission.

　　When we put this car on the road, the first thing that impressed us was not how strong the power was, but the suspension adjustment of this car. As a 6-seater /7-seater model, the suspension adjustment of the international version of Starway Moon Landing is soft, which can also handle the bumps on the road well and increase the comfort of the members in the car.

　　On the other hand, in terms of power, the new car is also equipped with a four-wheel drive system, so even in the economy and comfort mode, the power performance is relatively good, and the response time of the accelerator pedal is relatively fast. When we switch to the sport mode, the speed of the vehicle when shifting gears has changed obviously, and the feeling of shifting gears is also more obvious. Together with the use of shifting paddles, it also increases the driving pleasure of the vehicle to the greatest extent.

　　In terms of quietness, when the vehicle is driving at 80km/h, the control of wind noise and tire noise is very in place. However, when the vehicle speed is raised above 100km/h, the wind noise will increase obviously, but it is within the acceptable range. The tire noise and chassis performance are still excellent, and there is no sound coming out.

　　In terms of handling, although the car is large in size, the steering wheel is very flexible, even continuous line changing or one-handed operation can be easily completed. When turning around in a corner, the turning radius of the vehicle is quite satisfactory, but fortunately, the body is higher and it can have a better view.

　　The intelligent driving performance of the new car is also satisfactory, including ACC adaptive cruise, lane departure warning, rear car reminder and other functions are very easy to use, which also greatly relieves our fatigue when driving at high speed, and also improves the safety of the vehicle to a certain extent.

　　Summary:

　　As an SUV model for home use, Starway Moon International Edition has achieved the leading level of the same price in terms of appearance, interior technology, interior materials, intelligent driving performance and space. After all, the price range of this car is 22.89-23.89 million yuan, so it still has strong market competitiveness. So as a dad, will you consider this medium and large SUV?

　　[car home second-hand through train] Looking at the domestic SUV market, tanks are definitely one of the hot brands. Both (|) and Tank 500 have created sales records that demand exceeds supply, and even used cars are more expensive than new ones. Nowadays, the tank 800 frequently exposes spy photos. I believe that it is not far from you to leave the "Baoding Cullinan". But today, are the tanks 300 and 500 still so popular? Is the used car still so valuable? Let’s take a look at this issue together.

　　Different from Tank 300 and Tank 500, Tank 800 will be the flagship product of the "business luxury" route of tanks, and its design ideas will be more luxurious and atmospheric.

　　From the latest spy photos, we can see that the state of this vehicle is very similar to the version exhibited at the previous 2021 Shanghai Auto Show. We guess that the new car is also likely to be a tank 800 model close to the production version.

　　The more luxurious and atmospheric design is quite eye-catching, but besides the tank 800, the tank 300 and the tank 500 also have a very high degree of attention. If you want to be a "tank driver" earlier. Let’s take a look at the current market of tank 300 and tank 500.

　　The new cars currently on sale for Tank 300 are mainly two off-road models and three urban models, and the official version of Tieqi 02, which cooperates with Dinghuo. The official guide price ranges from 198,800 yuan to 302,800 yuan. As a hard-core off-road vehicle, this price range is still relatively close to the people, which is one of the reasons for achieving considerable sales.

　　However, since the second half of last year, the production speed of tank 300 has increased. Up to now, it is basically possible to pick up a car in about one month, and the popularity of new cars and the market for used cars of tank 300 have gradually declined.

　　Take the 2023 Conqueror version, which is more popular in the used car market, as an example. The guide price of a new car is 215,800 yuan, and a quasi-new car that has been licensed for about one year can basically sell for about 200,000-210,000 yuan. For the old conquerors around 2021, the second-hand price of standard car condition is around 190,000 yuan.

　　The standard car condition mentioned here is the normal kilometers of the car. In fact, as a hard-core off-road vehicle, the second-hand tank 300 can be said to be a car in one condition, not only to distinguish whether there is a history of off-road, but also to distinguish whether there is a modification.

　　In addition to post-modification, Tank 300 has introduced some original modified versions, such as Cyber Tank Edition, Border Limited Edition, Wind Forest Fighter, Tank Ranger and so on. Due to the official modification and limited sales, the prices of second-hand quasi-new cars of these models are basically 20,000-30,000 yuan higher than when the new cars land. However, with the continuous introduction of limited edition models and the decline in the popularity of new cars, the second-hand market of such models has gradually dropped.

　　Comparing the market, we can see that the tank 300 has indeed gradually reduced the heat and market from the previous "used cars are more expensive than new cars". However, in the same class and at the same price, Tank 300 is still the car with the highest rate of preservation and heat.

　　When considering used cars, it is recommended to consider quasi-new cars with short age and few kilometers. Although the price/performance ratio is not as high as that of old used cars, the problems reflected by the owners have been solved in the late batch, with better quality and more worry-free later. In terms of color, except for "Bai Fumei" and "I want red", they are basically popular colors with high preservation rate.

　　After talking about tank 300, let’s take a look at its "big brother" tank 500. In the eyes of many friends, tank 500 and tank 300 are also the light of domestic products. What about the second-hand market of tank 500?

　　The new tank 500 cars are mainly divided into Dengfeng/Terrace, Sport/Business, 5-seat /7-seat models, as well as the original factory’s special customized version with double colors. The price range of the new car is 335,000-395,000 yuan. However, in contrast, the new car sales of Tank 500 are not as high as those of Tank 300, and the second-hand market is relatively stable.

　　Take the sports version of the 7-seat environmental model as an example. The guide price of the new car is 363,000 yuan, and the new car is about 400,000 yuan. One-year-old second-hand quasi-new car, basically the purchase price is only 300,000 yuan, the individual transaction price is about 310,000-320,000 yuan, and the one-year preservation rate is about 80%.

　　Also affecting the current market of tank 500 is the launch of new models, namely the Hi4-T plug-in hybrid model. Before Tank 500, there was a lot of controversy about fuel consumption, and the Hi4-T plug-in hybrid model can solve everyone’s concerns about fuel consumption to a certain extent. Naturally, fewer people choose the 3.0T version, and the second-hand market will only fall but not rise.

　　Summary:

　　No matter the tank 300, the tank 500 or the future tank 800, they are all the benchmark products of China brand SUV. After the production capacity of tank 300 and tank 500 increased and the popularity of new cars gradually decreased, the market conditions gradually returned to normal. As consumers, we need to keep a clear head and rationally choose the right model according to our own needs.

　　Yiling District Public Security Bureau set up a special investigation class to carry out the investigation. The police in the special class found out that the information came from a company called "Wuhan Veterans Survey" through online investigation and collection, offline waiting, follow-up investigation and evidence collection.

　　The police followed the line and found a 10-member criminal gang headed by Pan. Based in Wuhan, the gang collects citizens’ information and needs through the internet, and conducts illegal and criminal activities such as finding a car, finding someone, collecting debts, inquiring about household registration, and inquiring about house opening records nationwide.

　　The police found that Pan, the leader of the gang, was the boss of the company, responsible for personnel deployment, business negotiation, information coordination, remuneration collection, etc. The gang members Xu, Tao, Zhang and others were responsible for promoting the company’s business through the network and contacting the GPS salesman to maintain the background, install GPS, find people, find cars, track and shoot.

　　On September 2, the police of Yiling District Public Security Bureau wiped out 10 suspects, including Pan, in Wuhan and Xiantao.

　　At present, the case is still under investigation.

The people’s governments of all districts and cities shall, according to the instructions of the Office of the Emergency Command Center for Heavy Pollution Weather or the changing trend of air quality in this Municipality, designate relevant departments to issue or remove early warning information for heavy pollution weather.

VI. Job Requirements

(1) Strengthen leadership and make careful arrangements.Construction, urban management, ecological environment and other departments at all levels should fully understand the importance of prevention and control of dust pollution in construction sites, do a good job in classified management and control, and implement the policy of exemption from management and control, not only to ensure the control of atmospheric environment, but also to support the smooth progress of engineering construction projects. It is necessary to do a good job in the classification and grading control of concrete enterprises, and ensure that the process requiring continuous concrete pouring can be carried out normally from the source. Local construction administrative departments should urge the construction site to take effective measures to realize "six hundred percent" of enclosure around the construction site, stacking and covering of dust-prone materials, wet earthwork excavation, road hardening, cleaning of vehicles entering and leaving, and closed transportation of muck vehicles, and install online monitoring and video monitoring equipment.

(two) rotating consultation, strengthen cooperation.The Provincial Department of Housing and Urban-Rural Development and the Provincial Department of Ecology and Environment have established a monthly rotating consultation mechanism to regularly communicate, exchange work information and study intersection issues. Departments of city construction, urban management and ecological environment can refer to this model, regularly strengthen research on issues of common concern and concern, and formulate scientific, reasonable and effective emergency control measures for heavy polluted weather while doing a good job in dust control at the construction site, so as to prevent frequent shutdown of the construction process and bring greater risks to safety production. Local construction administrative departments should master the management of construction sites during emergency control, assess the impact of heavily polluted weather on engineering construction, and report to the Provincial Department of Housing and Urban-Rural Development in a timely manner.

(3) Strengthen joint law enforcement and implement precise punishment.Local construction, ecological environment and urban management departments should make full use of the provincial comprehensive monitoring platform for pollution prevention and control, weave and compile the "tight encirclement" for monitoring environmental pollution, integrate online monitoring facilities of construction, urban management, ecological environment and other departments, further strengthen information sharing, and implement online dynamic management of pollutant discharge. To carry out joint law enforcement actions on a regular basis, the construction administration of each district and city.The competent department shall put forward the "six hundred percent" implementation requirements (see the annex for the "six hundred percent" implementation reference suggestions)three) to provide a basis for the subsequent implementation of joint precision law enforcement.The outstanding and difficult problems found in the inspection are entered into the comprehensive supervision platform, and the whole process is tracked and supervised to ensure timely rectification. Local construction administrative departments should increase the frequency of inspections during the emergency control of heavy polluted weather, and immediately order rectification if they find that illegal construction and dust control measures are not in place; It is necessary to urge construction units to strengthen dust prevention and control education; For construction sites that have not stopped or resumed work without authorization, severe punishment methods such as fines, notification, credit scoring, and restrictions on market access should be adopted to force the construction unit to implement the responsibility of dust prevention and control.

(4) Improve the positive incentive mechanism and implement differentiated management.Exemption policy is an important mechanism to encourage the development of environmental protection. Local construction administrative departments should urge construction enterprises and construction sites to strengthen pollution control, improve the pollution control level against industry benchmarks, and meet the conditions stipulated in the Administrative Measures for Exemption of Production Stop and Production Limit in Autumn and Winter in Jiangsu Province and Supplementary Notice on Strengthening Exemption Management of Production Stop and Production Limit in Autumn and Winter in Jiangsu Province, and encourage enterprises and project departments to actively submit exemption applications to local housing and construction departments. The construction department should take the lead in dynamic management of the exemption list of emergency management and control, include the qualified ones in the exemption list of emergency management and control, ensure that the incentive policies are put in place, and strengthen the clear orientation of "doing well is different from doing badly" in environmental protection. During the emergency exemption period, if any behavior contrary to the exemption conditions is found, the exemption qualification will be cancelled, and no application can be made again within six months. If the circumstances are serious, the relevant acts shall be carried out in accordance with the provisions of the housing construction credit score.

Coverage requirements, methods and scope

　

I. Coverage requirements

Construction sites should strengthen management measures such as sealed storage or covering of cement and other fine-grained building materials that are easy to fly.Strengthen the coverage of exposed ground, material storage yard and shutdown site. Dust prevention measures such as dust prevention net covering and vegetation planting can be adopted for all kinds of exposed ground, mound and foundation pit excavation. Dust prevention net covering or vegetation planting should be adopted for vacant areas according to the service period and function. When building materials such as sand and stone and construction waste are piled in the open air, dust prevention net should be used for covering. For temporary construction, the exposed area and time of earthwork should be reduced as much as possible.

Second, the way of coverage

Dust-proof coverage in the construction area can adopt single coverage or composite coverage. Single coverage refers to the coverage method of using only dust-proof net, and the density of dust-proof net should be as dense as possible, and the dust-proof net with flat wire of more than four needles should be used for coverage to achieve the effect of dust prevention and dust fixation. By planting vegetation, before the greening effect is achieved, the dust-proof net should be used to cover it separately to form a composite cover, so as to achieve the effect of dust prevention and dust suppression. The dust-proof covering net in the construction area must be compacted firmly, which can play a good wind-proof and dust-proof effect in a certain period of time.

III. Coverage

In view of the shallow groundwater level in some areas of our province, the soil is sticky, the water retention is good, and the excavation is mostly wet soil, which is not easy to produce dust. In addition, the muck is generally covered with dense mesh, and the material is easy to age, the recovery rate is low, it is non-degradable, and it is easy to produce secondary pollution. Therefore, the covering requirements for the following procedures in the construction site are defined.

1. Requirements for muck covering in pile foundation engineering

Radius and periphery of working face of pile driver10-15mScope of the site, can not cover; The site should be paved with temporary roads, and the roads should be kept clean.

2. Requirements for muck coverage of foundation pit (trench) engineering

In the process of foundation pit (trench) excavation, the bottom of foundation pit may not be covered; If the foundation pit (groove) is sloping, the slope may not be covered; Parts involved in safety observation may not be covered; Hardened channels should be laid on the upper and lower ramps of the foundation pit, and the channels should be kept clean without covering the ramps; The wet muck can be stored in the shield tunnel section and the soil pit of the mining method tunnel without covering.

3. Requirements for muck coverage of municipal road engineering

Filler soil, waste soil and lime soil piled on site shall be covered; Earthwork or lime-soil subgrade shop48After hours, it has not been compacted, or the surface layer is dry and loose with dust after compaction, which should be covered; Water-stable inorganic binder base, after compaction, the surface layer is dry, loose and dusty, which should be covered; Effective dust prevention measures should be taken when dust-prone operations such as lime-soil mixing, pavement unification, cutting and chiseling are carried out.

4. Requirements for muck coverage of earthwork backfilling and greening in the later period.

Radius and periphery of mechanical working surface10-15mScope of the site, can not cover; After stopping the operation or after the completion of the operation, it should be in48Covering in time within hours.

5. Coverage requirements along the ground of high-speed rail or subway

In the construction site near the high-voltage catenary of high-speed rail or subway, the dust-proof net may be moved by typhoon, tornado and other forces, which may affect the safety of the high-voltage catenary. It is not appropriate to cover it with dust prevention net (refer to the relevant regulations of railway and subway protection zones for the safety distance), and it is appropriate to plant vegetation to achieve the effect of greening and solid settlement.

"Six hundred percent" implementation reference suggestions

　

First, the enclosure around the construction site is closed

oneConstruction sites in urban areas and built-up areas should choose enclosure types according to engineering characteristics to ensure enclosure tightness. Time limit exceededsixA month and don’t need to change frequently, should adopt a fixed enclosure with a closed bottom; Time limit for a project issixTemporary enclosures such as water yards can be used for those less than a month or those that need to be changed frequently on site.

2. Before the demolition, the demolition part shall be closed and fenced at the expropriation site where the household relocation is completed.

Second, the material stacking cover

one．Set up a special stacking area for easy-to-dust materials, so as to take them as you use them and cover them as you use them.

2Set up temporary garbage storage yard reasonably, and pile up construction garbage in a centralized and classified way.24If it cannot be removed in time within hours, dust prevention measures such as 100% coverage and sprinkling water shall be taken.

threeWet soil may not be covered, and the dried soil shall be cleaned, transported, turned over or covered in time. About wet soil (moisture content>5%) can be confirmed by observing that there is no obvious dust on the surface, squeezing free water or being able to twist and shape.

Three, earthwork excavation wet operation

oneDuring earthwork excavation, sufficient fog gun dust suppression equipment should be equipped, and the road should be cleaned, but water and ice should be prevented from causing potential safety hazards.

2For wet soil that does not produce dust, water spraying or spraying is not required. The specific judgment method is the same as above.

Fourth, pavement hardening

oneTemporary hardened pavement on the construction site shall be cast-in-place concrete or prefabricated panels that can be recycled.

2In the foundation construction stage, it is suggested to use temporary steel plates with satisfactory rigidity to harden the pavement, but it should be ensured that the temporary roads do not slip, dislocate or be damaged in use, and should be replaced in time after being damaged.

Five, in and out of the vehicle cleaning

one. All the body and wheels of engineering vehicles leaving the construction site should be cleaned, and equipped with automatic washing facilities. Only after washing can they enter the social road.

2Use information technology to strengthen supervision. For the construction site where the site conditions permit, it should be required to be equipped with vehicle unwashed capture equipment or video surveillance, and the relevant data should be pushed to the regulatory authorities with law enforcement power.

Six, muck vehicles closed transportation

Accelerate the upgrading of muck transport vehicles, and gradually force the use of closed muck transport vehicles (recommendedPvcFlat-push sealing mode) to solve the problems of vehicle overload, spilling and dripping.
