CCTV News:We continue to pay attention to the bridge collapse accident in Heyuan, Guangdong Province. The day before yesterday, at 2: 12 am on June 14th, the Dongjiang Bridge, also known as Zijin Bridge, located on the Dongjiang River in Heyuan, Guangdong Province collapsed, causing two vehicles crossing the bridge to fall into the water, and three people fell into the water. One of them was rescued and the other two were thrown into the search and rescue.

　　　　　　 Yesterday (15th), many rescue forces, such as Nanhai Rescue Bureau, locked the position of the drowning vehicle in the continuous search and rescue of two drowning people. After many efforts, at 13: 05 today, this white off-road vehicle was salvaged ashore, and there was no one inside.

　　　　　　 The reporter saw at the scene that the Dongjiang River was still muddy and the water level dropped by about 30 cm. Two sea patrol search and rescue vessels are preparing to search and rescue the downstream of the bridge again. Members of the Blue Sky Rescue Team took several small boats to search for the collapsed bridge.

　　　　　　 In addition, the salvage team also launched a side-scan sonar to search and rescue. It is understood that the main task at present is to conduct search and rescue. The cause of the bridge collapse is still being identified and analyzed.

　　　　　　 It is understood that the collapsed Dongjiang Bridge is located in the suburb of Heyuan City. It was completed and opened to traffic in 1972 and has a history of 47 years. The bridge spans Dongjiang River and runs from northwest to southeast. It is a six-hole arch bridge and is also called "Zijin Bridge" by local people. Two people fell into the water in this bridge collapse accident, and we will continue to pay attention to the relevant search and rescue progress.

　　　　　　 On June 14th, on the same day that the Dongjiang Bridge in Heyuan, Guangdong collapsed, the traffic police squadron in Longjiang, Shunde, Foshan, Guangdong Province also issued a notice that the local Longjiang Bridge was closed due to settlement. Traffic on roads and waterways at the scene was interrupted.

　　　　　　 Yesterday morning (15th), when the reporter arrived at the Longjiang Bridge in Shunde, Foshan, he saw that both ends of the Longjiang Bridge, which is about 1 km long, had been enclosed. In the middle of the bridge deck, an expansion joint had been dislocated, and the rubber and iron pipes in the joint were exposed, and the dislocation height of the bridge guardrail could put down an adult’s palm. Due to the closure of the bridge, everyone’s travel has been affected a lot.

　　　　　　 According to a staff member of Shunde Highway Administration at the scene, Longjiang Bridge was built earlier. Usually, the Highway Administration will repair and maintain the bridge pavement, but it is the first time for them to encounter such settlement.

　　　　　　 At present, the navigation channel where Longjiang Bridge is located has also been closed. Relevant departments are monitoring and evaluating the structure and safety of the bridge, and the specific situation has not been announced yet. Although it has a certain impact on travel, fortunately, security risks were discovered in time to avoid accidents.

Cctv newsAccording to the news of Gongxin Micro-newspaper, in order to strengthen the cascade utilization management of power batteries for new energy vehicles, improve the comprehensive utilization level of resources and ensure the quality of battery products for cascade utilization, the Ministry of Industry and Information Technology, the Ministry of Science and Technology, the Ministry of Ecology and Environment, the Ministry of Commerce and the General Administration of Market Supervision jointly formulated the Measures for the Administration of Cascade Utilization of Power Batteries for New Energy Vehicles (hereinafter referred to as the Measures).

The "Measures" propose to encourage echelon utilization enterprises to cooperate with enterprises such as new energy vehicle production, power battery production and recycling and dismantling of scrapped motor vehicles, strengthen information sharing, and use existing recycling channels to efficiently recycle used power batteries for echelon utilization. Encourage power battery manufacturers to participate in the recycling and cascade utilization of waste power batteries.

Article 6 of the "Measures" points out that the echelon utilization enterprises should meet the requirements of the "Industry Standard Conditions for Comprehensive Utilization of Waste Power Batteries of New Energy Vehicles" (Announcement No.59 of the Ministry of Industry and Information Technology, 2019). Encourage the use of advanced and applicable technology and equipment, and give priority to the step utilization of waste power batteries at the package (group) and module level. The disassembly of battery packs (groups) and modules conforms to the relevant requirements of the Disassembly Specification for Recycling and Disassembly of Vehicle Power Batteries (GB/T 33598).

Article 13 of the "Measures" points out that the design of echelon products should comprehensively consider factors such as electrical insulation, flame retardant, thermal management and battery management to ensure the reliability of echelon products; Adopt a structure and connection mode that is easy to maintain, disassemble and disassemble, so as to facilitate the disassembly, disassembly and recovery after scrapping.

　　CCTV News:Not long ago, the Netan detachment of Zhoushan Public Security Bureau of Zhejiang Province and the Cultural Comprehensive Law Enforcement Detachment of Zhoushan Cultural Bureau cracked a case of spreading obscene articles for profit by using mobile APP, which was listed as a case supervised by the National Leading Group Office for Combating Pornography, and arrested Li, the producer of the mobile APP of Fast Fish Cloud Broadcasting, Yu, Shi and Ren, and found more than 7 million obscene video files in the mobile APP of Fast Fish Cloud Broadcasting.

　　In July this year, Liu Haibo, a grass-roots grid member of Zhoushan New Town Management Committee, found in his daily visit that many people were watching obscene videos using a mobile APP called "Fast Fish Cloud Broadcasting", which aroused his vigilance.

　　After mastering and fixing the relevant evidence, the Cultural Comprehensive Law Enforcement Detachment of Zhoushan Municipal Bureau of Culture immediately launched the joint disposal mechanism for eliminating pornography, provided relevant clues to the Netan Detachment of Zhoushan Public Security Bureau, and cooperated with the Netan Detachment to investigate related cases.

　　Access to overseas obscene websites is hidden.

　　After receiving the relevant clues, the Netan detachment of Zhoushan Public Security Bureau immediately filed an investigation. During the investigation, it was found that the "Fast Fish Cloud Broadcasting" APP was extremely confusing and concealed in the process of spreading obscene pornographic videos.

　　The police investigation found that the main page of the "Fast Fish Cloud Broadcasting" App is no different from the normal film and television App. Users can watch a large number of legal film and television works as long as they install it, but when they click on the sub-pages such as classification and search on the page, obscene pornographic video pages will pop up on the mobile phone. By purchasing the registration code and registering as a member, you can browse and watch these obscene video contents.

　　Gu Zhoutao, Deputy Team Leader of Netan Detachment of Zhoushan Public Security Bureau: "The criminal suspect made this mobile APP, and its communication route is mainly through his QQ group, WeChat circle of friends, or website. To watch obscene videos, you must first get an invitation code on your mobile phone and send a part of the invitation code to the card issuing website. "

　　After careful investigation, the police found that most of the registered users of this mobile APP purchased the "registration code" from a place in Huanggang, Hubei Province, and there are more than 1,500 registered members from all over the country, and the actual owner and maintainer of this mobile App is Li, a native of Xuzhou, Jiangsu Province. Li made the "Fast Fish Cloud Broadcasting" App, rented the Internet data cloud to set up a server, and finally accessed more than a dozen overseas obscene websites and more than 7 million obscene video resources.

　　Through further investigation, the police also found that 16 other people, such as Shimou from Yuyao, Ningbo and Renmou from Deqing, Huzhou, also bought apps from Li or purchased obscene video resources to access their own apps, and then spread them for profit. After mastering sufficient evidence, Zhoushan Public Security Bureau police rushed to Xuzhou, Jiangsu, Huanggang, Hubei, Yuyao, Zhejiang, Huzhou and other places, and successfully arrested suspects such as Li, Shi and Ren with the cooperation of local police.

　　Self-taught mobile phone application development is involved in pornography and is in jail.

　　Different from the previously uncovered cases of spreading obscene articles on the Internet, the case of "Fast Fish Cloud Broadcasting" spreading obscene articles for profit by using mobile App has the characteristics of fast spread, wide spread and large audience. The four people involved in "Fast Fish Cloud Broadcasting" arrested by the public security organs are all very young, and three of them are post-90 s. What is even more surprising is that Li, the developer of the mobile APP "Fast Fish Cloud Broadcasting", has only a first-year junior high school education.

　　Gu Zhoutao, deputy detachment leader of the Netan detachment of Zhoushan Public Security Bureau, said that it is difficult to block obscene videos spread by the "Fast Fish Cloud Broadcasting" mobile APP.

　　Gu Zhoutao, Deputy Team Leader of Netan Detachment of Zhoushan Public Security Bureau: "This software is very concealed. The cases encountered in the past spread through the cloud disk and are easily blocked by the public security organs. Connected through the mobile APP, it is very concealed and difficult to block, so these obscene video data quickly spread to the whole country. "

　　The registration code used by registered members of this APP is also very cheap online. The registration code is divided into day card, month card, half-year card, year card, permanent card, etc. The online price of permanent card is 98 yuan, and the cheapest day card only needs 2 yuan. From March this year, the "Fast Fish Cloud Broadcasting" went online for only six months until the incident, tens of thousands of people across the country have registered as members, and the relevant personnel have illegally made more than 100,000 yuan.

　　Because of his poor family, Li began to work after dropping out of school in the first grade of junior high school, and later taught himself the mobile APP method online. In the face of police interrogation, Li realized that his mistakes were irreparable. At present, four suspects have been transferred for prosecution.

　　The second stand

　　Many people find that after a few days of use, the mobile phone battery charges faster and faster, but the standby time is getting shorter and shorter. In order to make their mobile phone batteries more durable, many people choose to turn to the internet and follow the tips on how to extend the battery life. But you know what? Many online charging methods are wrong, and you have been cheated for so many years.

　　Should the battery be completely exhausted before charging?

　　No way! "Deep discharge" will damage the battery.

　　There used to be a saying that the battery has a memory function, and you must wait until the battery of the mobile phone is completely exhausted before charging it to 100%, otherwise the battery will "remember" the proportion that needs to be charged, so that it needs to be charged before the battery is used up, and the charging will not be full.

　　"Now smartphones use lithium-ion batteries, and the technology and structure of lithium batteries have undergone tremendous changes. It is wrong to recharge the mobile phone battery after it is completely exhausted." Wang Yonggang, a leading enterprise of new energy power battery and R&D engineer of Tianneng lithium battery, told the Science and Technology Daily reporter that the so-called "deep discharge" when the battery is completely exhausted may have an irreversible impact on the internal material structure of the battery and shorten the battery life.

　　When charging, positive lithium ions "jump" into the electrolyte from the positive electrode, "climb" through the winding holes in the diaphragm, "swim" to the negative electrode, and combine with the electrons running from the positive electrode early; The opposite is true when discharging. Dr. Zhang Hua, who graduated from the Department of Materials Science and Engineering at the University of California, Los Angeles, made an analogy: whether it is discharging or charging, lithium ions have to get away from the original structure, which is a bit like carrying a bunch of things from one room to another. Therefore, the understanding of battery life should be based on the understanding of battery structure.

　　That is to say, in the process of charging and discharging, the less lithium ions participate in the movement every time, the less damage to the structure; The slower the lithium ion running every time, the less damage to the structure. If the lithium ion runs almost, it is necessary to "deeply discharge" and continue to extract lithium ion from it, which will damage the battery.

　　Do you want to end charging immediately when the battery is full?

　　No need! Batteries have "overcharge protection"

　　When charging a mobile phone, Netcom should immediately stop charging when the battery is charged to 100%, otherwise it will damage the battery life.

　　In this regard, Wang Yonggang said, don’t worry too much. Lithium batteries are generally equipped with "overcharge protection". When the battery is almost full, it will automatically switch to trickle charging, that is, the charging is very slow and the current is very small. When the battery is fully charged, it will automatically cut off the power and will not continue to overcharge, so it will not have much impact if it is rushed to 100% at one time.

　　Many people like to charge their mobile phones overnight before going to bed. In this regard, Wang Yonggang said that turning on their mobile phones at night will also cause power loss, and how much power is consumed, the charger will continue to charge the mobile phones with small current. "But such a long cycle will have a certain impact on battery life."

　　Will sporadic charging damage the battery?

　　Wrong! "Shallow charge and shallow discharge" is good for batteries.

　　"Generally, the life of a lithium-ion battery can reach hundreds of charge and discharge cycles. The charge and discharge cycle here refers to the process of using up the electricity and then recharging it, rather than plugging the battery into a charger and then unplugging it once." Wang Yonggang said that "shallow charging and shallow discharging" of lithium-ion batteries, that is, sporadic charging, has little influence on the structure of anode and cathode materials, but will not affect the service life. "So, we usually emphasize that the charging and discharging of lithium-ion batteries should be shallow, and don’t challenge the ‘ Limit ’ 。” Zhang Hua said.

　　These practices also affect battery life.

　　Charging different models of mobile phones with non-original charger has its own matching charger. Using non-original charger may have an irreversible impact on battery performance due to the large current of the charger used.

　　Making phone calls, playing games and watching videos while charging are all high current consumption. The current provided by the charger is less than the current consumed by the mobile phone, so it is necessary to output current from the battery while using the mobile phone while charging. That is to say, at this time, the battery is not charging, but discharging, and even the battery capacity will be "exhausted" quickly. The life of lithium battery is closely related to the number of charge and discharge cycles. When using the mobile phone while charging, the battery will switch between charge and discharge rapidly, which will affect the service life of the battery.

　　When the mobile phone is placed in a high and low temperature environment, due to the instability of the electrodes in the electrolyte, the two electrodes of the battery will react chemically every time they are charged and discharged, and then the active substances will be consumed, and the chemical energy converted into electric energy will be reduced, and the battery capacity will be reduced. If the ambient temperature is too high, it will accelerate the chemical reaction and "self-discharge" of the battery and reduce the battery capacity; The low temperature below zero will also have a negative impact on the battery structure, even permanent damage.

Changes in the new year and season,

It deeply affects our choice of clothing.

　 　 　 　Becoming a soldier is the dream of many students, but taking the military school entrance examination requires not only the results of the college entrance examination, but also the candidates’ health, especially their eyesight. Many parents know that their children’s myopia needs to be improved, but they are not clear about the time needed for myopia surgery and what preparations need to be made. Below, experts will answer your questions.

　　First of all, we need to know the requirements for applying for military school vision:

　　The farsighted vision of each eye in the military academy is less than 4.5(0.3), the corrected vision is less than 4.9(0.8), and the diopter is above ±6.00DS equivalent spherical lens, which is unqualified.

　　The naked-eye farsightedness of each eye is above 4.6(0.4), the corrected vision is above 4.9(0.8), and the diopter is below ±6.00DS equivalent spherical lens. The majors of command, surface warship, submarine, armor, surveying and mapping and radar are qualified. Among them, excimer laser surgery has no complications for more than half a year, except submarine and airborne specialty.

　 　 　 　 Enter the military academy in 2022, and do laser myopia surgery as early as possible.

　　Whether it is full femtosecond or semi-femtosecond, the postoperative vision recovery is very fast. Normally, you can get good vision the next day after surgery, which will hardly affect your normal work and life. However, you should try to operate as early as possible and reserve enough time for vision recovery.

　　1. Myopia surgery can be done without wanting to do it. Many nearsighted friends came to the hospital and told me that I wanted to do all-femtosecond surgery, or other surgical methods. However, after strict preoperative examination, because the eye conditions did not meet, myopia surgery could not be performed. Even if it was found that it was not suitable for myopia surgery, there was enough time to adjust the plan.

　　2. Myopia surgery has strict requirements for patients’ eye conditions. If the eye condition does not meet the requirements, even if the corneal thickness is appropriate, the operation can only be performed after the eye condition meets the requirements. For example, it is necessary to stop wearing contact lenses in advance, soft contact lenses for 1 week, hard contact lenses for 2 weeks, and OK lenses for more than 3 months.

　　3. There are strict and standardized surgical procedures for myopia surgery. Generally speaking, you should have a preoperative examination before you can make an appointment for the operation. You should also order eye drops for three days before the operation, and it will take about 1 to 3 months for your vision to return to stability after the operation.

　　Therefore, experts remind that in order to ensure foolproof, the sooner you apply for myopia surgery in military schools, the better. With sufficient recovery time, you can not only successfully pass the physical examination, but also restore your eye vision to a stable state as soon as possible.

　　This year is a highlight year in the history of marathon. On October 12, Kenyan male athlete Kipkog broke the human limit in Vienna and successfully ran into the two-hour marathon. On October 13th, Kenyan woman Bridget Koschi broke the world best result in the women’s marathon, which has been maintained for 16 years, in Chicago. In the 39th Beijing Marathon, which ended on November 3rd, the men’s race record was also refreshed again.

　　In recent years, the number of marathon events and various road running events has been blowout. With the participation of more and more people, road running has gradually become an urban culture that leads the national fitness trend.

　　According to the Business Value Report of Sports Industry in China, among the sports that people often participate in, running ranks among the best with 43% participation. Road running, represented by marathon, has become one of China people’s favorite fitness exercises and an important platform for national fitness. In 2018, the total number of participants in the national marathon and related events was 5.83 million, an increase of 4.33 million over 2015.

　　A group of statistics on amateur runners and runners around the world released by IAAF in June this year show that in the past 10 years, only about 12% of all runners participated in the marathon (the marathon duration is 42.195 kilometers), while the number of people who participated in the half marathon (hereinafter referred to as "half horse") kept increasing, accounting for about 30%. The "5 km" has the largest number of participants, accounting for about 35% of all runners. In China, the scale of road runners is also growing.

　　So "5 km", "10 km", "half horse" and "whole horse", which event is suitable for you and how to run healthier? On November 2nd, more than 50 people, including leaders of more than 20 national road running/marathon trade associations and runners from Beijing, Inner Mongolia, Anhui, Jilin, Hebei, Jiangsu, Shandong, Shanxi, Shaanxi and Jiangxi, gathered in Beijing to participate in the symposium on "Marathon and Great Health" jointly held by "Healthy China" edition of China Youth Daily and Beijing Marathon Association. Participants discussed the relationship between road running and personal health, marathon and industry health, and marathon and social health atmosphere from the perspectives of education, medicine, media communication and the development of road running industry, so as to convey the concept of scientific fitness to fitness enthusiasts.

　　Marathon is an extreme sport, and every participant should treat it with caution.

　　There are probably the following motivations for people to participate in road running: at the physiological level, in order to keep healthy or lose weight; On the psychological level, in order to increase self-confidence, pursue the meaning of life and cope with negative emotions, gain a sense of accomplishment in competing with others and achieving personal goals; At the social level, I hope to associate with others and get recognition.

　　From illness to running 59 marathons (including 22 "all horses"), Wen Caifeng, a runner over 50 years old, started running for health. Because of encephalitis, she was once "immune" in college. After graduation, she went from sub-health to minor illness, and then she was hospitalized almost every year. Wen Caifeng realized that hospitals can only treat diseases and only exercise can make herself healthy, so she started running and ran into the marathon. Wen Caifeng’s running goal for himself is "no injury, longer, faster and healthier".

　　How to know the marathon, and what are the misunderstandings of the public about the marathon? Zhao Fuming, president of Beijing Marathon Association, said that people who never run talk about "horses", while some enthusiasts will excessively pursue personal best (PB). "First of all, we should realize that as amateur runners, we are far away from competitive sports. Even those who have the best performance among runners should also realize the gap and not aim too high; Secondly, it should be Do not forget your initiative mind. When running, ensuring health is the top priority, without affecting normal work and life, scientific fitness, and enjoying a healthier life through exercise. " Zhao Fuming believes that the marathon itself is an extreme sport, and every participant should be treated with caution.

　　Sports medicine experts teach you how to run safer.

　　Zhu Jingxian, a medical supervisor and sports physician in Peking University Institute of Sports Medicine, started with the case of sudden death in a marathon and analyzed who was not suitable for running a marathon. She warned everyone to run scientifically and safely, and to keep running for health.

　　"Marathon is a typical extreme challenge project, and its first finisher died suddenly at the finish line, which is enough to show us the risks of this sport. However, it is also a sport full of challenges and enjoyment. Regular running will make the brain secrete more dopamine and endorphins, which will make people happy and even ‘ Addiction ’ 。” Zhu Jingxian said.

　　According to incomplete statistics, since 2014, more than 20 runners in China have died suddenly in the "Half Horse" or "All Horse" race or after the race. Foreign literature statistics show that the incidence of sudden death in marathon is 0.6/100,000-1.9/100,000, while in China, the incidence of sudden cardiac death in the whole population is 41.84/100,000, which is much higher than that in horse racing. Zhu Jingxian believes that "we can do more work to further avoid tragedies, and nip in the bud is the key."

　　Zhu Jingxian said that people with cardiopulmonary diseases and potential heart diseases are not recommended to participate in the competition. How to find potential heart diseases, such as congenital heart disease and hypertrophic cardiomyopathy, is the key to reduce sudden cardiac death during or after the game. "We suggest that the contestants go to a regular hospital for the following examinations before the competition: electrocardiogram, echocardiography and cardiopulmonary exercise experiment. Physical examination before the game is very important. " Zhu Jingxian said.

　　Secondly, the contestants need to run step by step before the race, and regular running habits are the basis to ensure the completion of the marathon. "Generally speaking, people who have never run for a long distance, even if their physical fitness is good, are not recommended to participate in the marathon. For the first time, a strange sports event is prone to sports rhabdomyolysis, and in severe cases, renal failure may occur. " Zhu Jingxian said that for the first-time marathon runners, only after completing the running training equivalent to the whole marathon distance before the competition can they better play their level in the official competition, and at the same time reduce the risks of sports injuries and sudden death. Amateur masters who have participated in many marathons should also pay attention not to blindly pursue achievements. "You should pay attention to your feelings in the race. If you are unwell, stop the race in time and seek medical support. If you stay up late, catch a cold and are in poor health before the game, it is recommended to give up the game. "

　　"The most prone to cardiac arrest is the runner whose pace (a concept often used in marathon training, which refers to the time required for a runner to run 1 kilometer) is between 5 minutes and 6 minutes and 30 seconds, that is, ‘ Quanma ’ The competition takes 3.5 -4.5 hours ‘ Amateur master ’ . 52% of cardiac arrest occurred in the last 10 kilometers of the marathon. " Zhu Jingxian said.

　　The common sports injuries in running are mostly concentrated in hips, knees and ankles. Dr. Zhu reminded runners to do what they can. "For short-term injuries, they can be cured through rest and physical compensation; Reversible long-term damage can be cured by drug therapy+physical factor therapy+rehabilitation training; However, for irreversible long-term damage, surgery is needed, and it may also cause permanent functional loss. "

　　Dr. Zhu Jingxian reminded runners: nutritional supplements at ordinary times, before, during and after the game should be paid enough attention; Running equipment should be based on ensuring safety, and it is not expensive to be right. Finally, she particularly emphasized that muscle strength training is very important for runners. "Muscle strength is the armor that protects joints and the cornerstone of PB."

　　The road running industry is in its infancy and full of opportunities.

　　Zhu Donghui, secretary of the Party Committee of Beijing No.3 Middle School, is also a marathon runner. Together with the headmaster of No.3 Middle School who is also a runner, he has formed a 70-person teachers’ running group and has participated in several events organized by Beijing Marathon Association. At the same time, the school also designed a 3 km -10 km running training plan for students of different ages. "The sense of accomplishment of students holding special medals after the game is more effective than any kind of verbal mobilization. It is our ultimate goal to cultivate students’ healthy habits through the guidance of teachers. Running is a lifelong benefit, and I believe that running students can also influence parents and friends around them. " Zhu Donghui said.

　　Road running industry associations and various running groups all over the country are grass-roots organizations that undertake and lead the vast number of road running people. Zhao Fuming believes that at present, the road running industry is in its infancy and has good development opportunities.

　　In this year’s National Day mass parade, Beijing Marathon Association organized more than 200 members to participate in the first set-up running group phalanx. Up to now, Beijing Marathon Association has hosted, undertaken and co-organized 13 events, conducted 1,140 public welfare trainings and 20 certification trainings, with about 58,000 participants, covering the Beijing-Tianjin-Hebei region.

　　How should local trade associations achieve healthy development? Zhao Fuming believes that the nature and positioning of industry associations should be clarified; Form a work team with common goals; Implement valuable work items; In line with the national strategy of healthy China, it is the key to actively cooperate with government policies and requirements.

　　Create a social atmosphere of scientific movement and healthy life
