South Africa’s power generation capacity improves. Officials say they will gradually get rid of the power shortage.

  China news agency, Johannesburg, July 3 (Reporter Damon) As of July 3, local time, South Africa’s power rationing level has dropped to a lower level III, and the duration of power rationing has reached the shortest in the past two years. According to South Africa’s Minister of Electricity Ramohopa, South Africa’s power generation capacity has improved significantly at present, and South Africans are expected to be protected from the impact of continuous power cuts this winter.

  Since 2023, the problem of power rationing in South Africa has become more and more serious, and frequent power rationing measures have seriously affected the production and life of local people. At the beginning of the year, it once entered a state of national disaster due to large-scale power rationing. Especially with the coming of winter, the outside world has unanimously looked down on the power supply prospect of South Africa this winter.

  However, with the coming to power of La Mohopa and the continuous reform of the power system, the power supply situation in South Africa has been continuously improved. According to Ramohopa, the expert team of the South African National Power Company is working around the clock to ensure that the power generation capacity of the power company can meet the people’s higher demand for electricity in winter. At present, it can basically guarantee that there will be no power cuts for two-thirds of the day, and the supply and demand are gradually shrinking, which will gradually get rid of the power cuts in South Africa.

  According to Ramohopa, through strengthening internal supervision and the presence of the South African Defence Force, the current cases of sabotage and corruption against the South African power system have also been greatly reduced, which undoubtedly boosted the confidence of the outside world in the South African National Power Company.

  However, Ramohopa admits that there are still many generator sets in trouble, and the power supply system is still fragile and faces greater risks. Therefore, the South African people still need to be prepared to deal with the possibility of nationwide power cuts.

Promoting the Modernization of Natural Disaster Prevention and Control System and Ability —— Detailed explanation of the National Comprehensive Disaster Prevention and Mitigation Plan in the Tenth Fiv

  Xinhua News Agency, Beijing, July 21stTitle:Promoting the Modernization of Natural Disaster Prevention and Control System and Ability —— Detailed explanation of the National Comprehensive Disaster Prevention and Mitigation Plan in the Tenth Five-Year Plan

  Xinhua News Agency reporter Liu Xiacun

  Recently, the National Disaster Reduction Committee issued the National Comprehensive Disaster Prevention and Mitigation Plan for the 14th Five-Year Plan. This is the fourth comprehensive plan for disaster prevention and reduction at the national level in China. From what aspects will China’s disaster prevention and mitigation work be exerted? What kind of goals are achieved? At the press conference held by the Office of the National Disaster Reduction Committee and the Emergency Management Department on the 21st, the responsible persons of relevant departments made an interpretation.

  Strive to basically realize the modernization of natural disaster prevention and control system and prevention and control capacity by 2035.

  Regarding the planning objectives, Chen Sheng, director of the Monitoring and Disaster Reduction Department of the Emergency Management Department, introduced that from the first stage to 2025, a natural disaster prevention and control system with overall planning and efficiency, clear responsibilities, combination of prevention and control, social participation and coordination with high-quality economic and social development will be basically established; In the second stage, we will strive to basically modernize the natural disaster prevention and control system and prevention and control capacity by 2035, and the prevention and response to major disasters will be more powerful, orderly and effective.

  "Under the overall goal, the plan has defined 6 sub-goals and 12 major tasks in 2 major sectors." Chen Sheng said, on the one hand, we should strengthen the standardization construction, revise and improve the laws and regulations on disaster prevention and mitigation, establish and improve the investigation and evaluation system for major and extraordinary disasters, and improve all kinds of emergency plans and standards and norms in various fields; on the other hand, we should strengthen the mechanism construction, establish and improve the comprehensive coordination mechanism for natural disaster prevention and control, and improve the work pattern of joint management and coordination.

  Second, focus on disaster risk reduction, highlight source control, incorporate disaster risk assessment into the requirements of national spatial planning, build a national comprehensive risk database for natural disasters, and prepare a comprehensive risk map and a prevention and control zoning map to minimize disaster risks.

  Third, focus on efficient disaster relief, add a central disaster relief material reserve, improve the disaster emergency response mechanism and various rescue policies, and strengthen the linkage between early warning and emergency response.

  Fourth, focus on consolidating the foundation of disaster prevention and mitigation, deploy major projects to build scientific and technological support capacity for disaster prevention and mitigation, encourage the development of disaster prevention and mitigation industries, consolidate the grass-roots organization system for disaster prevention and mitigation, and extensively carry out popular science education on disaster prevention and mitigation. Every village (community) in urban and rural areas throughout the country has at least one disaster information officer.

  Release earthquake warning information within 10 seconds after catastrophic earthquakes in key areas.

  Zhou Weixin, deputy director of the Planning and Finance Department of the Seismological Bureau of China, said that the earthquake prevention and disaster reduction work during the 14th Five-Year Plan period will further consolidate the monitoring foundation, strengthen forecasting and early warning, find out the risk base, strengthen seismic fortification, ensure emergency response, enhance public services, innovate seismic technology and promote modernization.

  First, strengthen the capacity building of earthquake monitoring, forecasting and early warning. Accelerate the construction of earthquake monitoring network, and release earthquake early warning information within 10 seconds after catastrophic earthquakes occur in key areas. Strive to make short-term and imminent earthquake prediction with effective disaster reduction.

  The second is to strengthen the capacity building of earthquake disaster risk prevention and control. Accelerate the evaluation of seismic exploration zoning, complete the investigation of key hidden dangers of earthquake disasters in earthquake-prone areas nationwide, and compile the sixth-generation seismic zoning map. Accelerate the strengthening and reconstruction of houses in earthquake-prone areas and improve the seismic fortification capacity of buildings.

  The third is to strengthen the capacity building of earthquake emergency rescue. Provide automatic and rapid evaluation opinions on earthquake disasters within 15 minutes after the earthquake, provide rapid evaluation results of earthquake disasters within 40 minutes, and provide opinions on earthquake trend judgment within 60 minutes, which provides support for efficient and orderly earthquake rescue tasks.

  China is one of the countries with the most serious meteorological disasters in the world. Deng Shizhong, deputy director of the Emergency Disaster Reduction and Public Service Department of China Meteorological Bureau, said that a meteorological disaster risk prediction and early warning service system should be established by disaster types, regions and industries, and meteorological disaster impact prediction and risk early warning services should be developed. Strengthen comprehensive disaster reduction, promote the meteorological service guarantee of the whole chain of natural disaster prevention, resistance and rescue, improve the linkage mechanism and progressive early warning service mechanism with meteorological disaster warning as the guide, and build the first line of defense for disaster prevention and mitigation.

  Within 10 hours of the disaster, the basic livelihood of the affected people was effectively rescued.

  Lai Hongzhou, deputy director of the Disaster Relief Department of the Emergency Management Department, introduced that the plan clearly stated that disaster relief should be more powerful and efficient during the 14 th Five-Year Plan period, and the basic livelihood of the affected people was effectively rescued within 10 hours of the disaster. He said that the National Disaster Reduction Committee and the Emergency Management Department will focus on the planning objectives, and further strengthen the capacity building of disaster relief from the aspects of detailed resettlement and assistance for the masses, ensuring the supply of disaster relief materials, and doing a good job in departmental emergency linkage.

  Lai Hongzhou also introduced that at present, China has built a five-level disaster information officer system at the provincial, city, county, township and village levels, with a total of more than 1 million people, most of whom are part-time cadres at the grassroots level, covering all urban and rural communities in the country, and disaster-prone areas are also equipped with A and B corners. Disaster information officers at all levels are mainly responsible for reporting disaster statistics, and at the same time take into account the tasks of early warning information transmission, disaster hidden danger investigation, dangerous information reporting, etc., and assist in the emergency relocation and life assistance of the affected people.

  Lai Hongzhou said that the main purpose of building this team is to build a nationwide disaster information statistical reporting network to ensure that people at the grassroots level report disasters, will report disasters, and report them accurately and quickly. Every disaster information officer plays the role of "nerve endings". In case of emergency, he can timely transmit disaster information to the "brain center", providing important information support for the decision-making of party committees and governments at all levels in emergency rescue and disaster relief, and minimizing the loss of people’s lives and property.

Ministry of Transport: The temporarily closed toll stations and service areas resumed operation.

  On May 11th, the State Council held a routine briefing on the State Council policy, and Li Guoping, the safety director of the Ministry of Transport, introduced the situation of doing a good job in ensuring the smooth flow of logistics. Li Guoping said that with the joint efforts of all localities and departments, the toll stations and service areas of the national highways have been quickly restored to operation, and the "arteries" of highways have been quickly opened and the achievements have been effectively consolidated. From April 21st, the number of closed toll stations will be kept within 20, and the number of closed service areas will be kept within single digits. On May 4th, the country achieved the goal of dynamic zero clearing for the first time. Subsequently, because some drivers and passengers were involved in the epidemic and vehicles stopped, some expressway service areas were shut down again. On May 10th, the temporarily closed service area resumed operation, and the country once again achieved dynamic zero clearing. With the full resumption of operation of closed toll stations and service areas and the continuous promotion of various measures, the situation of blocked goods logistics has improved rapidly, and the traffic volume of national highway networks, especially trucks, has continued to rise steadily. As of May 10th, the national expressway traffic totaled 21,877,300 vehicles, an increase of 26.39% over April 10th. Among them, the flow of trucks was 7.213 million, an increase of 25.65% over April 10.

Man’s "Complaint" 12315: Obviously, it is reported that the merchant sells fake goods. How can it be handled as a complaint?

Tiantian 315.png

"Your complaint meets the acceptance conditions. Please go to the Airport Branch of Jieyang Municipal Market Supervision Administration in Guangdong Province for on-site mediation on June 19th." Looking at this complaint mediation notice, Tan Ming (pseudonym) is very puzzled. He expressed his incomprehension to the reporter of the upstream news hotline 966966/ upstream news APP: "Obviously I am a’ report’, how can I become a’ complaint’?"

Reporting fakes but receiving a complaint mediation.

On May 26th this year, Tan Ming bought a hair dryer on an e-commerce platform. After receiving the goods, Tan Ming suspected that he had bought a fake because of the poor packaging and the lack of relevant brand information. "Later, I applied for an invoice, but I was directly rejected." Tan Ming feels that he may not only encounter the behavior of selling fake and shoddy products, "this enterprise is more likely to evade taxes."

Report 2.png.

△ Tan Ming’s billing application was rejected.

On the morning of June 8, Tan Ming, who thought more and more wrong, decided to report the enterprise to the 12315 national Internet platform. "I remember very clearly that after logging in to the website, I chose the’ reporting’ channel, because what I wanted was not compensation, but after reporting the behavior similar to’ selling fake goods’, I asked the relevant departments to investigate and deal with it according to the investigation facts."

Report 3.png.

△ Tan Ming’s report content on the platform.

But what Tan Ming didn’t expect was that on the afternoon of the report, the seller got through his phone and added WeChat, requesting to cancel the relevant complaint. "After that, I received the complaint acceptance letter and mediation notice from the market supervision bureau there."

△ screenshot of the conversation that the merchant actively contacted.

Tan Ming said, "According to the relevant regulations on market supervision and management of complaints and reports, my identity information should be protected, but the accepting unit informed the’ reported person’ of my’ report’ as a’ complaint’. Can the two be switched?"

"Reporting" or "Complaining" needs to be reviewed and decided.

The reporter immediately logged on to the 12315 national internet platform and found that "complaints" and "reports" were displayed on the home page in two channels. Articles 5 and 6 of the "Notice for Reporting" pop up by clicking on the "Reporting" channel clearly indicate that due to the different handling procedures of reporting and complaints, the reporting cannot contain complaints, and the platform will keep the informer’s information strictly confidential.

Report 1.png.

Report 5.png.

How to make sure that your report does not contain complaints? The staff of the 12315 Consumer Complaint Reporting Hotline explained that reports and complaints do belong to two acceptance channels, and the biggest key point to distinguish them is whether consumers have "demands". "If there are, they will be accepted by the complaint channel, and if not, they will be accepted by the report channel."

So why is Tan Ming’s "reporting" content treated as a "complaint"? "Because there are often complainants who can’t distinguish these two concepts, we will actually judge the specific content of complaints and reports when we review them." The relevant staff of the Airport Branch of Jieyang Municipal Market Supervision Administration of Guangdong Province told the upstream journalist, "If the complainant has other needs, such as not wanting to be mediated or insisting on reporting, he can contact us at any time to communicate."

Lawyer’s statement > >

Differences and requirements between complaints and reports

Are complaints and reports the same thing? Liu Xian, a lawyer of Beijing Deheheng (Chongqing) Law Firm, believes that to answer Tan Ming’s doubts, it is necessary to follow the Interim Measures for Handling Complaints and Reports of Market Supervision and Management, which came into effect on January 1, 2020. This method is an effective law and regulation on the handling of consumer complaints and reports by market supervision and management departments.

According to the provisions of Article 3 of the Measures, complaints and reports are clearly defined by law: reporting refers to the behavior that natural persons, legal persons or other organizations report to the market supervision and management department that operators are suspected of violating the laws, regulations and rules of market supervision and management; Complaint refers to the behavior of consumers who purchase or use goods or accept services for their daily consumption, have a dispute with business operators about consumers’ rights and interests, and request the market supervision and management department to resolve the dispute.

"Therefore, if there is a consumer rights dispute with the merchant due to the purchase of goods, it is a complaint; If it simply reflects illegal business operations, it is a report. " Liu Xie said that from the content reflected by Tan Ming alone, it is more likely to be characterized as a "complaint" because there is controversy about the goods he personally purchased.

Liu Wei introduced that if consumers want to complain, they should provide relevant information such as name, telephone number, mailing address, name and address of the respondent, and explain that the complaint request is the fact of consumer rights dispute; If you want to report, you should provide clues suspected of violating the law and be responsible for the authenticity. The market supervision department shall keep confidential the relevant information and handling of the informant and shall not disclose it to irrelevant personnel.

How to save yourself from a car accident caused by a fire on Shaanxi Fuyin high-speed bus?

  Wei Minzhou, member of the Standing Committee of Shaanxi Provincial Party Committee and secretary of Xi ‘an Municipal Party Committee, and Du Hangwei, vice governor, went to the scene to direct the disposal and rescue of the wounded.

  Xi ‘an Net News: At about 12: 40 on April 28, a long-distance bus with the license plate number Shaanxi AG7597 caught fire 200 meters in front of the lawn tunnel in Lantian section of Fuyin Expressway, causing 8 deaths and 5 injuries. After preliminary investigation by the public security organs, it was a criminal case of hijacking and arson. After receiving the report, Wei Minzhou, member of the Standing Committee of the Provincial Party Committee and Secretary of the Municipal Party Committee, Du Hangwei, Vice Governor, and Shangguan Jiqing, Mayor, rushed to the scene immediately to direct the disposal and rescue of the wounded.

  Wei Minzhou, Du Hangwei and Shangguan Jiqing made arrangements for the treatment and rehabilitation of the wounded after on-site inspection and listening to the relevant situation of the case. First, immediately organize health, public security, fire protection, transportation and other departments to carry out rescue, at all costs, do their best to rescue the wounded and do their best to minimize casualties. Second, the public security department immediately set up a task force to fully investigate the case. The third is to properly do a good job in appeasement and rehabilitation of the families of the casualties, and timely announce the medical treatment and case investigation to the public. The fourth is to strengthen social prevention and control and maintain social security and stability.

  At present, the case is under investigation, traffic has been restored, and various aftermath work is being carried out in an orderly manner.

  Liu Chunyan, Deputy Secretary of the Municipal Party Committee, Lv Jian, Ren Junhao and Huang Haiqing, leaders of the city, relevant municipal departments and the principal responsible comrades of Lantian County attended the on-site disposal.

  How to save yourself when a long-distance bus fires.

  Before introducing all the survival knowledge, we should focus on the cliche that you should fasten your seat belt at all times as long as you are in the car, because the seat belt is the most effective safety facility whether you are hit at rest or while driving. In addition, it is suggested that everyone should abide by traffic laws and regulations, not speeding or driving illegally, and minimize the chance of accidents. It is best to have no place to display survival skills.

  At present, there is little information about how to save yourself in a car accident in China, which can be said to be very imperfect, and there is no relevant department to publicize and educate everyone how to deal with it when a car accident occurs.

  First of all, let’s start with self-help. If a vehicle has an accident, there are usually the following situations: two vehicles collide when driving relatively, and a bicycle rear-ends other vehicles or hits a fixed object, or rolls over and rolls over after being hit by other vehicles. How to save yourself after the car rolled over after the accident, please look down.

  If you first determine whether you are seriously injured after a collision, and if you are in good health, you must try your best to get out of the car. First of all, you must try to escape by opening the door, but in most cases, the car body is damaged after the collision, and it is difficult to open the door and the car body. If you can’t open it several times, you must choose to break the window.

  How to escape when the people in the car are not injured, but after the accident, the members in the car will be hurt more or less, and they can’t do their best in the case of physical injury, so I suggest you try to escape by opening the car door first. If any glass is broken by impact, that’s your escape exit. And if all the glass in the car is intact and the door can’t be opened normally, then escape by using tools in the car or breaking the glass.

  A traffic accident claimed 36 lives. At about 2: 40 am on August 26th of a certain year, a serious traffic accident occurred near Huaziping service area in Ansai County section of Baomao Expressway in Yan ‘an City, Shaanxi Province. A double-decker sleeper bus collided with a large tanker (filled with methanol) and the two cars caught fire. A total of 36 people were killed in the accident, and only three people escaped from the accident.

  In recent years, long-distance bus accidents have increasingly entered the public’s field of vision, and every tragic accident has knocked on the fragile mind of reality. When we delve into the loopholes in the system and the lack of management, we should strengthen our own fire safety awareness. Strong desire for survival and skillful escape skills can make us more calm in the face of terrible accidents. When you escape, you can also save the lives of others.

  In the accident, the bus was embedded in the tanker for about 2 meters, and the door on the right front side of the car body could not be opened. In the design of the bus, there was only one front door. The car is closed except for the last two windows. In this accident, the fire developed rapidly, and the methanol leaked from the tanker in the accident will burn quickly when it meets an open flame in the air. It is understood that the fire surrounded the whole car two minutes after the impact, and the bus at this time has become a "human purgatory." The time left for passengers to escape in this accident is only two minutes, and we can’t know what the 36 dead people were thinking in the last two minutes of their lives.

  The dead are long gone, and the living are often sad. We should know and learn how to escape from a burning accident car.

Flying in the sky | Listening to astronauts telling hard-core stories behind "holding hands" in space

CCTV News:The rendezvous and docking of the Mengtian experimental module and the space station assembly can be said to be the space "handshake" of the two spacecraft with the largest mass in China’s manned spaceflight project, and the control difficulty is obviously increased. To this end, researchers have also come up with many ways to enable them to "shake hands" steadily in space.

This time, the Mengtian experimental module will rendezvous and dock with the space station assembly, which can be said to be the most "powerful" space handshake in China’s space history. The Mengtian experimental module weighs 23 tons, while the space station is a "four-module" combination consisting of Tianhe core module, candlestick experimental module, Shenzhou-14 manned spacecraft and Tianzhou-4 cargo spacecraft, with a total weight of more than 60 tons. In order for these two behemoths to complete rendezvous and docking, they must "shake hands steadily" and minimize the impact force between them.

Liang Xiaofeng, overall chief designer of space station system electricity of the Fifth Academy of Aerospace Science and Technology Group:In order to overcome the impact of large impact on equipment during docking, in fact, some special designs and damping designs have been made in rendezvous and docking to adapt to large-tonnage and large-mass rendezvous and docking. In the whole docking process, the relay is slowed down or reduced to protect the whole docking mechanism and reduce the impact on the whole assembly and equipment.

Another big test of this rendezvous and docking is that the Mengtian experimental module carries two huge solar panels, which are not only large in area, but also made of flexible materials, just like carrying a pair of huge "soft wings" for rendezvous and docking, and the control difficulty can be said to be unprecedented. To this end, researchers also designed a set of solar array deployment scheme for Mengtian experimental module, which improved the controllability and ensured the safety and success of the mission.

Chao Luo, the overall designer of the space station system of the Fifth Academy of Aerospace Science and Technology Group:When we docked, the solar wing kept shrinking and flying. After docking, we completed the second deployment of the solar wing.

Space "holding hands" is difficult, and multiple measures are taken to ensure success.

The Mengtian experimental module is similar to the candlestick experimental module launched three months ago, but the rendezvous and docking process is "difficult" and "difficult". In order to solve these problems, researchers have designed a large number of plans and measures to ensure the final success of the rendezvous and docking.

According to reports, the first difficulty of this rendezvous and docking is that after the Mengtian experimental module is in orbit, there is a big deviation from the angle of the sun, which leads to weak power generation capacity of solar panels and energy shortage. If the rendezvous and docking cannot be completed within the specified time, it is necessary to urgently adjust the posture of "Mengtian" towards the sun to replenish energy, which will lead to the delay of rendezvous and docking time. To this end, researchers have specially formulated a failure plan for the rendezvous and docking mission for "Mengtian".

The second difficulty lies in the goal of this rendezvous and docking — — On the space station assembly. In the last rendezvous and docking, the combination was in a symmetrical configuration, but in this rendezvous and docking, the combination was in an L-shaped asymmetrical configuration, which significantly increased the difficulty of the on-orbit attitude control of the space station.

Chao Luo, the overall designer of the space station system of the Fifth Academy of Aerospace Science and Technology Group:Pitch offset is adopted at a certain angle, which can save a lot of propellant and effectively use space torque. Then, when the Mengtian module enters the final translation and convergence section, the pitch angle will be adjusted to a completely horizontal state to wait for the rendezvous and docking of the Mengtian experimental module.

In addition, when Mengtian approaches the assembly, it is necessary to start the reverse thrust engine to slow down, and the plume of the engine will interfere with the attitude of the assembly, which makes it more difficult to dock the Mengtian experimental module with the space station at the last minute. However, under the "careful design" of scientific researchers, Mengtian experimental module accurately identified the relative distance and posture with the space station assembly, and finally achieved high-precision rendezvous and docking through a little approach.

Three-type solar wing provides abundant energy for China Space Station.

After the docking and transposition of Mengtian experimental module and China Space Station, China Space Station will form a T-shaped configuration, and China Space Station will also use three different solar wings at the same time.

During the planning and design of China Space Station, researchers developed three generations of solar wings according to the characteristics and needs of different cabins, each with its own characteristics. Shenzhou manned spacecraft uses the first generation of rigid solar wings, and Tianzhou cargo spacecraft uses the second generation of semi-rigid solar wings.

Liu Bihai, deputy director of the power supply of the Mengtian experimental cabin of the Space Station of the Eighth Academy of China Aerospace Science and Technology Corporation:In the first generation, we used a rigid substrate, which was made of carbon fiber and aluminum honeycomb, and its volume was relatively large. On the basis of the further improvement of the original power demand, our cargo ship uses the second generation semi-rigid solar wing, which uses a carbon fiber frame and a glass fiber net, just like a tennis racket, greatly reducing the weight of the whole solar wing.

Compared with shenzhou spaceship and cargo spacecraft, the two experimental cabins of the space station are very large. At the same time, the experimental cabin also needs to carry a large number of cabinets to complete a number of on-orbit experiments, which consumes a lot of electricity. To this end, researchers have specially developed the third generation of flexible solar wings to ensure the electricity demand of the experimental cabin.

Liu Bihai, deputy director of the power supply of the Mengtian experimental cabin of the Space Station of the Eighth Academy of China Aerospace Science and Technology Corporation:At present, the solar wing used in Mengtian experimental module is our third generation solar wing, which is called flexible solar wing. It has the characteristics of light weight, long life and high power. The power generation capacity of two solar wings in a single cabin is about 18 kilowatts. Generally speaking, the power generation capacity of my single experimental cabin in a dream day can be used by a family of three for three months.

After the combination of Tianhe, Zhentian and Mengtian, the daily power generation of the space station can reach nearly 1000 degrees, making the Chinese space station truly "worry-free".

A new generation of solar wings empowers "dream days"

A new generation of flexible solar panels adds new impetus to China Space Station. What is this flexible solar panel like? What are the characteristics? Follow the reporter from the reception desk to have a look.

General Station reporter Chen Qingbin:The electric energy converted from solar energy is the energy source of spacecraft in orbit. What is different from ordinary spacecraft is that on the Mengtian test module launched this time, it is such a pair of "soft wings" behind me — — Flexible solar panels. As you can see, the veneer of this solar panel is less than 1 mm thick, which can be described as "as thin as paper", and there are many small mirrors with dark blue glass on it. Each small mirror is like a small space power station, which is connected in series and in parallel to form a solar cell array to provide a continuous energy guarantee for the spacecraft.

The solar panels of Mengtian experimental module adopt the latest generation of solar array technology in China — — The flexible triple junction gallium arsenide solar cell array is composed of hundreds of thousands of flexible solar cells. The weight per unit area of these flexible solar cells is only 50% of that of traditional solar cells, but the photoelectric conversion efficiency has been greatly increased.

Su Bin, Head of Solar Array Project of Space Station of CLP Energy Co., Ltd.:The conversion efficiency of triple junction gallium arsenide solar cells is more than twice as high as that of traditional ground silicon cells.

In order to ensure the on-orbit life of the space station, the research team continued to develop high-voltage flexible solar array technology, and completed more than 80,000 high-and low-temperature cycle tests to ensure the structural stability and flexibility of the solar array. It is expected that the design life of the low-orbit solar array will be improved from 5 years to 15 years.

Bird flu, what you should know.

Since the winter of last year, affected by many factors, such as abnormal climate, the global animal avian influenza epidemic has been on the rise, affecting nearly 40 countries and regions in Asia, Europe and the Middle East. Our reporter learned from the National Health and Family Planning Commission that the number of cases of H7N9 epidemic (human avian influenza) in China has increased, and most of them are distributed in the Yangtze River Delta and Pearl River Delta regions. Contact with infected poultry or exposure to the live poultry market is an important risk factor for human infection. There is evidence that the virus can’t spread widely among people. From February 6 to 12, 2017, 69 cases of H7N9 were reported nationwide, with 8 deaths. At present, the number of new cases is on the decline. Experts predict that there will still be sporadic case reports in mainland China in the near future. Regarding H7N9, the National Health and Family Planning Commission summarized the following knowledge points:

1. What is the H7N9 epidemic?

The H7N9 epidemic is caused by H7N9 virus. Since the first case of human infection with H7N9 was discovered in East China in 2013, seasonal epidemics have occurred in winter and spring every year.

2. What are the main clinical manifestations of 2.H7N9 cases?

The incubation period is usually less than 7 days, or as long as 10 days. Pneumonia is the main clinical manifestation. Patients often have fever, cough and expectoration, which may be accompanied by symptoms such as headache, muscle aches, diarrhea or vomiting. Severe patients’ condition develops rapidly, and severe pneumonia occurs in 3~7 days after onset. Most of them have a temperature above 39℃, and they have difficulty breathing, which may be accompanied by hemoptysis and phlegm. It often progresses rapidly to acute respiratory distress syndrome, septic shock and multiple organ dysfunction syndrome. A small number of patients can be mild, only showing symptoms of fever with upper respiratory tract infection. The early onset of H7N9 cases has no specific manifestations, and it is difficult to diagnose and treat early. The treatment effect of severe cases in the later stage is poor and the mortality rate is high. At present, the overall mortality rate of reported cases is about 40%.

3. How does the 3.H7N9 virus spread?

The most important risk factor for human infection with H7N9 virus is direct or indirect exposure to the environment polluted by infected live birds or infected birds. There is no evidence that H7N9 virus can be transmitted to humans through properly handled poultry or eggs. In addition, eating cooked food will not infect H7N9 virus. There is no evidence that H7N9 virus can continue to be "human-to-human".

4. Who are the high-risk people infected with H7N9 virus?

Mainly retirees, housework and unemployed people, rural people; Mostly middle-aged and elderly people; Most cases have basic diseases; The vast majority of cases had contact with live poultry before onset or had been to markets where live poultry were sold. People engaged in non-scale and non-standardized poultry breeding, selling and slaughtering have more opportunities to be exposed to infected poultry, and the risk of infection is higher.

5. Is there a vaccine to prevent the disease? Can seasonal influenza vaccine prevent H7N9?

There is currently no vaccine available to prevent H7N9 virus infection. Seasonal influenza vaccine does not prevent H7N9 influenza.

6. How can we reduce the occurrence of severe cases and deaths of H7N9?

The use of antiviral drugs, such as oseltamivir phosphate (Tamiflu), has the best effect as soon as possible after onset. The clinic of comprehensive patients by medical staff

Bed manifestations and suspicious exposure history, suspected of being infected with H7N9 virus, antiviral drugs should be used as soon as possible, without waiting for the results of pathogen detection, so as to reduce the possibility of patients progressing to severe disease.

7. Will the epidemic get worse?

According to the epidemic law in the past, the number of cases will decrease obviously after the Spring Festival every year, and it will be at a low level until the end of April. At present, the upward trend of the epidemic has been contained.

8. Can poultry be eaten at present?

Birds such as chickens and ducks can be bought and eaten, but they must be eaten safely. First, we should pay attention to avoid direct purchase of live birds, direct contact with live birds and self-slaughter of live birds; Second, don’t buy live birds from mobile vendors; The third is to remind the elderly, especially those with basic diseases and poor physical fitness, to avoid or reduce contact with live birds as much as possible.

Jiujiang city cried …

September 15th. The soldiers are gone. Jiujiang city cried.

Hundreds of thousands of Jiujiang citizens, who stayed up all night, went out before dawn, waiting on both sides of the street, tearfully bidding farewell to their life and death, and their soldiers who fought against the flood for more than 50 days triumphed.

Jiujiang people said: In the days when the dike burst, it was the soldiers who blocked the surging flood with their chests, and it was the soldiers who exchanged their lives for our lives!

It is these soldiers who cleaned the streets of Jiujiang before leaving. I quietly transported the saved 314,500 kilograms of rice and 90,000 pieces of clothes to the levee for the victims, and squeezed out 1,629,600 yuan from my only tens of yuan allowance and low salary to the disaster area …

For fear that the troops would leave at night, the citizens spontaneously organized themselves and took turns to "be on duty" at the gate of the army camp from September 10: we can’t let the soldiers leave quietly!

At 5 o’clock this morning, the military vehicle came out. But when the car just left the door, it couldn’t move any more. Thousands of Jiujiang people rushed to throw gifts such as apples and eggs into military vehicles.

At this moment, the soldiers all raised their hands to the brim-salute!

At this moment, the soldiers and citizens’ chests are ups and downs, with tears in their eyes.

The saluting soldiers are like statues.  

The citizens are still rushing to throw gifts at the car.

In the crowd, a teenager was holding a slogan in his hand. It was written in crooked Chinese characters: "I want to be a soldier when I grow up." His name is Zhao Boxi, and he is one of the children who were rescued by the soldiers when Jiang Xinzhou burst its banks late at night on August 5.

A group of female students from Jiujiang Teachers College have already discussed it these days. When the military vehicles passed by, they rushed out of the school gate and raised their slogan: "Brother Bing, I really can’t bear to let you go!" " A young woman in a sundress got up the courage to rush nearby and threw a cigarette into the car.

When he arrived at Jiujiang Traffic Building, Hu Minli, a 30-year-old employee, ran back to the factory in a hurry, climbed high with the national flag and danced wildly.

At the Arc de Triomphe erected by the citizens, there was a sea of people. Flowers, colorful flags, slogans, the sound of cars, songs and firecrackers all converge into one piece: "Goodbye, soldier brother!" "Long live the People’s Liberation Army!"  

Wave. Shake hands. The tearful soldiers sang "Our Soldiers" and "Say the Truth" over and over again.

A 20-year-old young woman surnamed Yao shouted to the two soldiers in the car: "Da Li, Dajiang. Do you still know me when you come to Jiujiang in the future? "

Through the telephoto lens, the reporter saw that the tears of the two soldiers had hung on their cheeks.

At 8: 30, the first military vehicle arrived at Jiujiang West Station. Less than 5 kilometers, I walked for three and a half hours!

At 8: 45, there are five minutes before the train leaves. Liu Heping, a 54-year-old worker of Jiujiang Cement Factory, and more than 50 women suddenly squeezed out of the boiling crowd and blew the flute. People sang "Farewell" and "Beijing has a golden sun" loudly.

Lieutenant General Dong Wanrui, a group army soldier who stood by and said goodbye to the soldiers, choked: "I am proud to have soldiers who are so loved by the people." Tears ran down the general’s face.

At 8: 50, the train started. There was a cry on the platform.

The more you drive, the happier you are! The AI smart driving maze of Zhiji LS6 is "fire" out of the circle

Since its launch last month, Zhiji LS6 has gained extensive attention in the industry due to its leading edge in high-end intelligence. On October 20th, we were fortunate to test drive this peak masterpiece in Nanjing Ginkgo Lake Park. This Zhiji LS6 "smart driving" experience can be described as textbook level. With the blessing of Zhiji’s "Future Smart Cabin" series of leading intelligent technologies, Zhiji LS6 focuses on the pain points of urban commuting scenes to create "Super Smart Driving 6th Space". With unprecedented immersive scene-based intelligent test driving space and tailor-made challenges, we set up "smarter ‘6’ AI smart driving maze experience area", "high-performance ‘6’ performance driving control experience area", and in-depth experience of Zhiji LS6 "Future Smart Cabin", "Quasi-900V Super Performance Platform" and "International Fan Design".

The most intelligent test drive in history

At a time when traditional SUV performance tests are cookie-cutter, how can the test drive activities be innovative? As the "strongest 6 series in history", for the Zhiji LS6, the performance test is only the basic operation, and the intelligent peak experience is the core competitiveness of the Zhiji LS6.

In order to deeply experience the high-level intelligence of Zhiji LS6, Zhiji LS6 has created a super smart driving sixth space, pioneered the new gameplay of "AI smart driving maze", simulated the typical road conditions, traffic and people flow in big cities, and deeply experienced the future smart cabin in the commuter meta-universe. It has the ultimate performance experience and comprehensive driving control experience. It comprehensively tests the strength of the "strongest 6 series in history" and sets the industry benchmark with the "most intelligent and fun test drive in history". People have to be amazed by the all-round caring ability of this future smart cabin.

The big screen can understand

Can you imagine that a car can still drive normally when the front and rear glass, windows and rearview mirrors are all black? The Zhiji LS6 easily passes the test in the "Ultimate Blindfold Challenge" in the dynamic test drive. With the blessing of the "Global Digital Vision Blindfold" function, the Zhiji LS6 can easily pass in narrow and complex road conditions in the state of full blindness, with the powerful assistance of Zhiji’s original global digital vision blinding and traditional 360 panoramic images.

When you are driving in the city streets and encounter sudden heavy rain, don’t worry, the rainy night mode of Zhiji LS6 is ready to escort you in the scene of extremely poor visibility. Whether it is the safety blind spot or the fog blocking of the rearview mirror, you can use Zhiji’s global digital vision to make up for the blindness, as if one eye is lit in the dark, so that you can drive with confidence and boldness.

Super practical one-click AI driving

In the dynamic test drive, complex parking spaces, narrow alleys and other areas were set up on the test drive site to comprehensively test the practicality of Zhiji LS6’s one-button parking, one-button escape, one-button welt, and one-button tracking functions.

When you drive into a congested street, the only parking space is narrow, and the distance between the front and rear cars is limited, it can’t help but make people feel anxious. At this time, Zhiji LS6 is the best intimate little assistant. The functions of "one-click parking" and "one-click escape" can let you relax your hands, feet and mood, and leave all the problems to it to complete. When you accidentally get into a dead end and can’t turn around, "one-click tracking" will let you no longer worry. Zhiji LS6 has the strongest brain and can automatically remember the path of 50m distance, take you out of trouble smoothly, and return to the spacious and safe road surface to continue flying.

How about it, this is the absolute advantage of Zhiji LS6! When many new energy manufacturers are still thinking about "what a really easy-to-use smart car should look like in the state of human-machine co-driving", Zhiji LS6 has taken the lead in proofing – with "serving the driver" as the core, through intelligent technologies such as global digital vision blinding and one-click AI driving, it not only easily solves the road’s right-turn blind spot to rush out of electric vehicles, blurred rearview mirrors on rainy nights, stickers that are too difficult to worry about scratching, and narrow parking spaces that cannot be driven out. "Open the eyes of the left hand, and get the last meter of the road with the right hand", but also bring fresh and interesting AI interactive experiences such as SHUA and Zhiji generative large models. No matter the present or the future, the LS6 will be a smart car that is easy to use, easy to drive, fun, and worth closing your eyes to.

The first exposure of Xiaomi YU7 real car without camouflage: it’s so beautiful, and it will definitely sell well next year.

[TechWeb] On December 20 th, today, a group of undisguised photos of Xiaomi SUV model YU7 were circulated on the Internet, which were more realistic than the previous official maps and declaration maps. According to the current information, this model will be officially launched from June to July 2025.

In terms of appearance, Xiaomi YU7 continues the family-style design of SU7, and the overall shape is the style of cross-border SUV. The front face adopts the iconic "water drop headlights", but the details are slightly different from those on SU7.

From the side, the shape of Xiaomi YU7 is indeed the same as that of Ferrari Purosangue as previously rumored, but it can be confirmed that it will not adopt the design of opposite doors. In detail, the new car uses a hidden door handle instead of a semi-hidden design which is highly praised on the SU7. The high probability is to further reduce the wind resistance.

In addition, the new car also offers brand-new five-position wheels, and yellow brake calipers are available in tyre size in 19-inch, 20-inch and 21-inch.

In the rear part, Xiaomi YU7 also continues many designs on SU7, such as the classic "halo taillight" and small tail, as well as the rear diffuser.

In terms of power, Xiaomi YU7 will adopt pure electric drive and be equipped with dual-motor four-wheel drive system, with power of 220/288kW (about 299/391 horsepower), total power of 508kW (about 690 horsepower) and maximum speed of 253 km/h.

In terms of batteries, Xiaomi YU7 will be equipped with ternary lithium batteries. The manufacturers of batteries and assemblies are from Jiangsu Times and Zhongzhou Times respectively, both of which belong to Contemporary Amperex Technology Co., Limited. Although the battery capacity has not been announced this time, it is expected that the minimum will be 100kWh.
Regarding the selling price, it is definitely higher than that of SU7. At present, it is generally speculated in the industry that the selling price range will be around 300,000-400,000 yuan. (Xiao Jian)
