　　[PConline information]In summer, the most comfortable thing is to play with your mobile phone while eating watermelon in an air-conditioned room. In the big summer, such a hot summer, my life is definitely given by air conditioning. But as we all know, if you want to enjoy it, you have to pay. The biggest power consumption in summer is also air conditioning. Usually, the electricity bill in July and August is just a few hundred dollars. Whenever I receive the electricity bill, I always feel that the cost of continuing my life in summer is really high. Does the power consumption of air conditioners have to be so large? As the saying goes, many a mickle makes a mickle. Is there any clever way to save electricity?

　　Working principle of air conditioner

　　Refrigeration is the most commonly used air conditioner. After the air conditioner is powered on, the low-pressure vapor in the refrigerant in the refrigeration system in the air conditioner will be sucked by the compressor and compressed into high-pressure vapor, which will be discharged to the condenser. The outdoor air sucked by the axial flow fan will flow through the condenser, so that the high-pressure refrigerant vapor will be condensed into high-pressure liquid, which will be sprayed into the evaporator after passing through the filter and throttling mechanism, and will evaporate at the corresponding low pressure to absorb the surrounding heat, so that the indoor air will continuously circulate and flow, thus achieving the purpose of reducing the temperature.　　　　

　　Frequent switching consumes electricity instead.

　　Some people may think that it costs electricity to keep the air conditioner on, so they turn it off when it is not hot, thinking that the purpose of saving electricity can be achieved by constantly turning it on and off, but in fact it may cost more electricity. Because the power required by the compressor inside the air conditioner is very large when it is started, it is generally about 4 or 5 times higher than the normal working current. As a result, it will naturally cost more electricity to switch the air conditioner on and off frequently. In addition, it is easy to burn out the compressor if the air conditioner is turned on and off frequently.

　　Small coup of saving electricity in life

　　1. Unplug the air conditioner when it is not in use, because as long as it is plugged in, the air conditioner will consume electricity. Although the power consumption is not much, its power consumption cannot be ignored over time.

　　2. Turn on the air conditioner in summer, and don’t pursue too low a temperature, which not only consumes more electricity, but also easily causes symptoms such as colds. According to scientific data, the most suitable temperature for human body in air-conditioned room is 26℃~28℃, which can not only make people feel cool, but also make them more comfortable and save electricity.

　　3. If you go out for a short time, usually within an hour, there is no need to turn off the air conditioner, because as mentioned above, it is more electricity-consuming to switch the air conditioner at high frequency.

　　4. When cooling, the air outlet of the air conditioner is upward, because the cold air flow is heavier than air and will sink, so the cooling efficiency will be more obvious when the air outlet is upward.

　　5. When sleeping at night, choose the sleep mode that comes with the air conditioner. Generally, the air conditioner sleep mode will make the machine run in a low power state, which will not only make the noise less, but also make the sleep more comfortable with proper air volume.

　　6. In an air-conditioned room, the air temperature is low. At this time, with an electric fan, the cooling effect will be better. Because the power of the fan is far less than that of the air conditioner, and the fan can stir the air, making people feel cool. The air conditioner makes the indoor air cool, and the coolness is more obvious after being matched with an electric fan, so that the temperature of the air conditioner can be raised, which is more comfortable and saves electricity.

　　7. When installing the outdoor air conditioner, we should also avoid it being exposed to direct sunlight, because the outdoor air conditioner will radiate heat into the ambient air in summer, and the direct sunlight will increase the difficulty of heat loss, and the cooling effect of the air conditioner will become worse. If conditions are limited, we can install a sunshade. Try to choose thicker curtains indoors, and then close them, which can also reduce the loss of chill.

　　8. The last point is to clean the air conditioner regularly. Because of the long-term use of the air conditioner, the internal filter screen of the air conditioner will be covered with pollutants such as dust, and in serious cases, bacteria, mites and Legionella will also breed. It will not only block the vent, which will reduce the refrigeration efficiency, but also affect our breathing health. It is best to clean it once every half a month or once a month when using it at ordinary times.

　　Learn these tips, I believe we can save a lot of electricity bills, and use air conditioners correctly, which is environmentally friendly and saves electricity. Why not? Of course, it is really pleasant to stay in an air-conditioned room in summer, and everyone should pay attention to controlling the time. When the temperature is not high every morning and evening, opening the window for a few hours will help everyone’s health.

　　Spring is full of flowers and vitality, but it also brings some troubles. From yesterday (12th), Beijing entered the first high-incidence period of willow catkins, which mainly affected the inner city of the Fifth Ring Road. Populus tomentosa was the main species of catkins. The Beijing Municipal Bureau of Landscaping and Greening and the Beijing Meteorological Bureau jointly issued a forecast for the beginning of willow catkins.

　　Beijing: willow catkins enter the first high-incidence period.

　　From April 7th, the catkins of willows began to float in Beijing, and the whole process is expected to last until the end of May, totaling about 50 days.

　　Jaco, Deputy Director of Science and Technology Department of Beijing Municipal Bureau of Landscaping and Greening.In the season of flying flocks, we strengthen joint defense and linkage with urban management departments, health and health departments and meteorological departments, and bring the prevention and control of flying flocks into the scope of fine management of the whole city to improve the monitoring of flying flocks. Let the public know when there are flying flocks and which key areas are flying flocks, increase cleaning and humidification, and suppress flying flocks in time.

　　It is estimated that there will be three rounds of high incidence of floc in spring and summer.

　　According to the forecast of Beijing Garden Department, this kind of flying catkins will occur three times in spring and summer. From late April to early May, flying catkins mainly affect the main city and plain areas, and in mid-May, it mainly affects the mountainous areas. Each round of high-incidence period is generally about one week, and the high-incidence period is from 10 am to 4 pm every day.

　　So, where did these flying flocs come from? Poke the video ↓ Look at the self-report of a poplar.

　　I am a poplar, and my friend Liu Shu and I are native trees in Beijing, and have settled in Beijing since the 1960s and 1970s. Every spring, after pollination, our female plants will produce small capsules, which are wrapped in white flocculent hairs, and some seeds the size of sesame seeds are hidden in the hairs. When the mature capsule splits, the fuzz will fly with our seeds in the wind, which is what you can see.

　　Therefore, the flying floc itself has obvious seasonality and periodicity, and it is a harmless natural phenomenon. However, when it comes to weather with rising temperature, sufficient sunshine and low air humidity, "children" will have fun and fly all over the sky, which will have an impact on everyone’s life.

　　Physical prevention and control, scientific and technological means, multi-measures to control flying flocs

　　Willow spreads seeds by wind, and breeds offspring, which makes people hard to prevent. At present, Beijing is taking comprehensive prevention and control measures for flying flocks in many parks and streets in the main city to minimize the interference of flying flocks on people’s lives.

　　General Desk reporter Gao XueToday, the weather in Beijing is sunny and dry, and the wind force reaches level 4. We can see some flying flocs flying in the air. At present, the main source of flying flocs at this stage is poplar.

　　There are some willow tidbits falling down on the ground, which are wet. There are many tidbits like this on the nearby lawn, and the damp white flying tidbits are directly attached to the lawn, so they can’t dance with the wind.

　　In the period of high incidence of flying flocks, like the Beijing Olympic Forest Park where we are located, the key areas will be humidified and cleaned twice a day, and the tidbits will be knocked down with high-pressure water guns, which will increase the surface humidity and greatly reduce the flying flocks.

　　In addition to the wetting operation, it is also a means to control the total amount of flying flocs by pruning some branches in advance before the willow capsules crack and produce flying flocs.

　　In addition to physical prevention and control, according to the principle of combining the length with the length and treating both the symptoms and the root causes, the landscaping department of Beijing has also adopted scientific and technological means such as grafting male plants, raising seedlings through science and technology and improving tree species.

　　The seedling in this small flowerpot, which is in the hardening stage, is the artificially selected male non-flocculent Populus tomentosa-"Jingxiong No.1". In about two years, this seedling can grow to a height of about 5 meters, and it will be used as an urban landscape tree.

　　Some viewers may also ask, since female willow trees will produce flying flocs, why not just cut them down? In an interview, the staff of Beijing Bureau of Landscaping and Greening told us that willow trees have settled in Beijing for decades, such as this piece of Yang Shulin, with an average age of nearly 20 years.

　　The highest in the center of this picture is poplar, with an average height of about 25 meters. In front of the red building is Liriodendron, with an average height of 12 to 15 meters. In addition, there are Magnolia grandiflora and Pinus tabulaeformis commonly seen in Beijing, which are much shorter than poplar trees in height. Therefore, poplars have always been called the green skyline of Beijing. Without poplars, it means that the green skyline of Beijing will drop by about 10 meters, which will do great harm to the landscape and ecology of the whole city.

　　At present, the volume of willow trees in Beijing accounts for about 40% of all trees, and about 5.7 million trees can be accurately located and monitored in the main city. Last year, Beijing has gradually replaced about 20,000 "old, weak, sick and disabled" poplars with cultivated male non-flocculent Populus tomentosa, and the number of seedlings has reached 50,000.

　　It is a long-term process to control flying flocks. Through continuous scientific prevention and control, I believe that the impact of flying flocks on our lives will gradually decrease in the future.

　　Shandong: The combination of physical and chemical means to control the "disturbing people" caused by flying flocs

　　As the temperature rises, not only in Beijing, but also in many places in the north every April and May, there will be fluttering willow catkins. How to reduce the trouble of "disturbing the people" by flying catkins? Let’s see what measures Shandong has taken.

　　There are many Populus tomentosa in this residential area in Zhangdian District, Zibo City, and the local area has adopted the method of combining physical control with chemical control to control flying flocs.

　　Li Tiandong, Deputy Section Chief, Maintenance Department, Zhangdian District Comprehensive Administrative Law Enforcement Bureau, Zibo City, Shandong ProvincePhysical prevention is to use high-pressure waterwheel spraying and fog gun truck to accelerate settlement, and then to combine mechanical sweeping with manual cleaning in time. In chemical control, female plant flower bud inhibitor is mainly used to reduce flower bud differentiation.

　　In Dezhou City, the urban management department is comprehensively counting the male and female willow trees within its jurisdiction and carrying out targeted treatment such as drug control. Up to now, 112,400 poplar trees have been identified and marked in urban areas, including 59,600 female trees and 52,800 male trees.

　　Gao Na, Senior Engineer, Landscaping Service Center, Dezhou City Administration Bureau, Shandong ProvinceAccording to the previous general survey, we managed the willows in the jurisdiction by setting points, routes and personnel. The introduced "Beilin No.1" poplar male plant variety has been successfully cultivated, and the next step can be to replace and update the female willow plant in the green space.

　　Small coup of life: flying floc protection and cleaning have doorways

　　Flocculation is flying all over the sky, and sometimes it is easy to fly into people’s eyes and nostrils, causing discomfort. So in the period of high incidence of flying floc, what aspects should we pay attention to when traveling and exercising, and look at the small coup ↓

　　Jaco, Deputy Director of Science and Technology Department of Beijing Municipal Bureau of Landscaping and Greening.The high incidence period of flying flocs in each area is very short, only 3 to 5 days. In these three to five days, I suggest that one of the citizens who travel is able to wear a mask in time; Second, exercise can be carried out in the morning or evening, when flying catkins are not high every day. At home, for example, flying floc can be suppressed by watering can or vacuum cleaner, because flying floc has good hydrophilicity, and it will not fly as long as it touches water.

　　Experts remind that people with allergic skin should try to avoid skin contact with flying flocs. If allergic symptoms appear, they should go to the hospital in time and use antiallergic drugs to relieve symptoms under the guidance of doctors. Do not take medicine by yourself or ignore symptoms, so as not to aggravate the condition.

　　Fire warning: flying flocs are flammable and must be guarded against.

　　During the flying season, in addition to preventing allergies, we should also raise awareness of fire prevention. The main component of flying floc is fiber, and it contains a lot of vegetable oil, which is easy to burn when it meets a fire source, causing a fire. Look at the tips given by the fire department.

　　Catkin is extremely flammable, burning fast and dangerous. Don’t light catkins at will. After landing, catkins can be cleaned in time by splashing water, sweeping and burying, so as not to leave a fire hazard. Don’t put combustible materials such as cartons, branches and woodpiles around buildings, and pay more attention to cleaning combustible materials in time to eliminate hidden dangers; Poplar catkins attached to combustible materials should be cleaned up in time to prevent them from igniting combustible materials.

　　Wang Peng, a fireman of Daxing District Fire Brigade.Whether indoors or outdoors, you must take good care of the fire and don’t throw cigarette butts around to avoid fire. Schools and parents should strengthen the education of children, and it is forbidden for children to play with fire, let alone light catkins for fun and curiosity.

　　Yangcheng Evening News reporter Ma Hanqing

　　The data shows that in the first half of 2018, Guangdong’s economic operation continued the development trend of "overall stability, stability and improvement", achieving a regional GDP of 4,634.193 billion yuan, a year-on-year increase of 7.1%. According to the data analysis, the "one core, one belt and one district" in various cities in Guangdong has obvious advantages in their respective industries, and the old and new kinetic energy are continuously transformed, and the producer service industry is developing well … … On the 9th, Guangdong Provincial Bureau of Statistics released a brief report on the GDP of various cities and regions in Guangdong in the first half of this year, and many development highlights were eye-catching.

　　"One Core, One Belt, One Area" has its own advantageous industries.

　　In the first half of this year, the GDP of the Pearl River Delta region increased by 7.2%, maintaining the leading position in the province; The east and west wings are basically stable, with the east wing increasing by 6.1% and the west wing increasing by 5.6%; The mountainous area slowed down, with an increase of 3.9%.

　　From the perspective of economic aggregate, the GDP of Shenzhen and Guangzhou in the first half of the year was above 1 trillion yuan, reaching 1,100.938 billion yuan and 1,065.298 billion yuan respectively; The total regional GDP of Foshan and Dongguan is 447.598 billion yuan and 386.860 billion yuan respectively. The total amount of seven cities such as Huizhou and Zhongshan is between 100 billion and 200 billion yuan; The total amount of 10 cities such as Jieyang and Zhaoqing is below 100 billion yuan. In terms of growth rate, among the regional GDP of 21 cities, Zhuhai has the highest growth rate, with an increase of 8.7%; Followed by Shanwei and Shenzhen, with an increase of 8.2% and 8.0% respectively.

　　The report pointed out that Guangdong’s "one core, one belt and one district" has different advantageous industries. The so-called "one core, one belt and one area" refers to the coastal economy formed by the core area of the Pearl River Delta, eastern Guangdong, western Guangdong and the cities of the Pearl River Delta, and the ecological development area dominated by the mountainous areas of northern Guangdong. In the first half of the year, the industrial growth in the Pearl River Delta region was 7.5%, which was 1.6, 4.6 and 3.6 percentage points higher than that in the east wing, west wing and mountainous area respectively, which strongly supported the steady and progressive development trend of the Pearl River Delta. The dominant industries in the East Wing are transportation, warehousing and postal services (up 14.2%) and for-profit services (up 25%). The financial industry (up 8.0%) and real estate industry (up 6.3%) in the West Wing are better than those in other regions. The for-profit service industry in mountainous areas (up by 20.1%) has also developed rapidly.

　　In the first half of the year, the proportion of service industry in regional GDP generally increased. In 15 of the 21 cities, the proportion of service industry in regional GDP increased year-on-year, and Jieyang increased the fastest, with a year-on-year increase of 7.7 percentage points. Yangjiang and Heyuan also increased by 4.9 and 4.1 percentage points respectively.

　　New and old kinetic energy are continuously transformed, and the industrial structure is continuously optimized.

　　From the perspective of pulling factors, the financial industry and real estate industry are affected by policy regulation, and the pulling rate of each region has declined, reflecting the obvious role of financial "risk prevention" and real estate "deleveraging" policies. At the same time, the pulling rate of for-profit service industry to various regions has generally increased, and its pulling rate to the Pearl River Delta, East Wing, West Wing and Mountain Area has increased by 0.4, 0.5, 0.4 and 0.4 percentage points respectively, which has become an important driving force for economic growth in various regions, and the quality and efficiency of various regions have steadily improved.

　　From the perspective of industrial structure, Guangdong’s performance in the first half of this year is equally bright. In the first half of the year, the added value of Guangdong’s modern service industry was 1,585.792 billion yuan, an increase of 9.2%, 1.0 percentage points higher than that of the tertiary industry. The growth rate of modern service industry in 14 cities is higher than that of regional GDP. Shanwei, Shenzhen and Yangjiang are the fastest growing cities, with growth rates of 13.1%, 11.5% and 9.6% respectively, which are 4.9, 3.5 and 6.0 percentage points higher than that of regional GDP in this city.

　　In the first half of the year, the added value of producer services in Guangdong was 1,294.113 billion yuan, an increase of 7.1%. The growth rate of producer services in various cities is 1.5%— Between 12.0%, Shanwei, Yangjiang and Shantou grew rapidly, increasing by 12.0%, 11.8% and 11.3% respectively. As a producer service industry-rich area, the Pearl River Delta achieved an added value of 1,180.402 billion yuan in the first half of the year, up 8.0% year-on-year, accounting for 86.8% of the province. Producer services in the east wing, west wing and mountainous areas increased by 10.9%, 9.1% and 6.4% respectively, which were higher than the growth rate of the tertiary industry, accounting for 20.0%, 18.6% and 20.2% of the regional GDP.

　　In the first half of the year, the added value of Guangdong’s private economy was 2,439.569 billion yuan, an increase of 7.2%, which was 0.1 percentage point higher than the regional GDP in the same period, accounting for 52.6% of the regional GDP. The growth rate of private economy in 21 cities is between 0.9% and 10.9% respectively, and the growth rate of private economy in 12 cities is higher than that of their regional GDP.

　　Professional suggestions to accelerate industrial upgrading and regional coordinated development.

　　In the report, the Guangdong Provincial Bureau of Statistics combined with the analysis of the GDP of various cities and regions in the first half of the year, and put forward three suggestions for accelerating the development of various cities:

　　— — Accelerate the transformation and upgrading of industrial structure. Increase the support for emerging industries and the cultivation of technological core competitiveness, focus on improving the quality and efficiency of the supply system, and enhance the momentum of sustained economic growth; At the same time, continuously optimize the business environment, reduce the cost of industrial enterprises, and solve the problem of financing difficulties for small and medium-sized enterprises.

　　— — Promote the high-quality development of the service industry. Improve the leading role of the service industry in economic development, vigorously develop all kinds of producer services that serve the transformation and upgrading of export processing enterprises, and develop high-end life services, especially accelerate the development of socialized pension, medical care, housekeeping, community and other services. Seriously implement the real estate policy, maintain the stability of the financial system, and promote the stable and healthy development of the real estate market and financial market.

　　— — Focus on building a regional development pattern of "one core, one belt and one district" and accelerate the coordinated development of regions. We will fully implement the new regional development strategy led by functional areas, form a new development pattern consisting of the core area of the Pearl River Delta, the coastal economic belt and the northern ecological development area, base on the functional orientation of each region, differentiate the layout of transportation infrastructure, industrial parks and industrial projects, develop cities with their own characteristics according to local conditions, and vigorously promote regional coordinated development.

　　Xinhua News Agency, Guangzhou, May 24th Question: 14 days before the college entrance examination, this guide is given to candidates.

　　Xinhua News Agency reporter Zheng Tianhong

　　There are still 14 days before the 2022 college entrance examination. During these two weeks, how to prevent and control the epidemic situation before the exam? How to adjust the mentality, diet and health before the exam? What should I pay attention to in the final preparation? The reporter interviewed relevant experts and sorted out a preparation guide for candidates.

　　[14-day monitoring] The national college entrance examination will be held on June 7 -8. According to the previous requirements of the Ministry of Education, candidates should do a good job in local health monitoring for 14 consecutive days before the exam to reduce unnecessary gathering and cross-regional mobility, not going to places with large population mobility, and not going to areas with medium and high risk levels.

　　"Under the epidemic situation, we should prepare for the college entrance examination in accordance with the guidelines, take sufficient measures, and conduct scientific epidemic prevention. During the preparation period, candidates should maintain the living conditions of school and home at two o’clock and one line, wear masks, keep social distance and wash their hands frequently; Cooperate with the school to do a good job in nucleic acid testing, and timely declare personal health and action track for 14 days; Reduce social interaction with your family and manage your health code and itinerary code. Foreign candidates must rush back to the city where the college entrance examination is registered in time. " Yao Xunqi, president of affiliated high school of south china normal university, said.

　　[Scientific work and rest] In addition to paying attention to personal protection, a scientific and reasonable work and rest is the guarantee of health. Cheng Yuya, a senior in grade three of Guangzhou No.5 Middle School, suggested that candidates should keep enough sleep and not drive the "overnight train". The content arrangement of candidates’ daily review can be consistent with the subject time of the college entrance examination, and try to adjust the best biological clock to the time period from 9: 00 am to 11: 30 am and from 3: 00 pm to 5: 00 pm.

　　[Balanced diet] Normalization of diet, giving consideration to nutrition, and avoiding tonic. A number of preparation experts suggested that the diet before the exam does not need to eat extra supplements or health products, so as to maintain daily balanced nutrition; You can eat lightly, try to eat less fried foods or spicy foods with high fat content to avoid getting angry or diarrhea; Drink more water and less drinks to avoid the physical burden caused by gastrointestinal discomfort.

　　Specific to three meals a day, candidates can choose cereal, pasta, egg milk, fruit, etc. for breakfast, and the food for lunch and dinner can be diversified, including fish and shrimp rich in high-quality protein, lean meat, eggs, milk, tofu, etc., properly matched with vegetables and fruits, and a small amount of meals can be added at night, so as not to increase the burden on the stomach and affect sleep.

　　[Preparing for the exam and returning to the basics] What should candidates review in the final preparation stage? Yao Xunqi suggested that the number of questions should be reduced, and return to the basics and textbooks.

　　"In the final two weeks, candidates should adjust the preparation status to ‘ Peak ’ State. Looking up from the sea of questions, we should independently and pertinently scan a blind spot of knowledge, and avoid grabbing at the eyebrows and beards, and the examination papers of various subjects will fly all over the sky. At this stage, we must start from the foundation, sort out the core knowledge system, and then return to the foundation. " Cheng Yuya said.

　　[Normal mind test] The last two weeks are when students are prone to psychological fluctuations, and psychological adjustment is very important. We should deal with the college entrance examination with a "normal heart". Try to jump out of the college entrance examination to see the college entrance examination. The college entrance examination is only an experience on the road of life, not the end, and there must be reasonable expectations.

　　After studying, you can adjust your mood through exercise, music and reading. Li Ming, a teacher at Yuexiu School of Guangdong Experimental Middle School, said that exercise can stabilize the heart rate, release stress, help people sleep more, and make people clearer. It is recommended that candidates run and sweat in the evening, not too intense; A light music that resonates with you can help you relax and have more confidence. After brainstorming and exploring the sea every day, a collection of essays or poems is a paradise in your mind, which will help improve your brain and improve your writing inspiration.

　　When the college entrance examination meets the physiological period, some parents will let their children take drugs to avoid it artificially. Relevant experts said that the fluctuation of a body’s state is not enough to affect the ability to play in the examination room, because candidates’ level and ability to take the exam have already had a very stable output after years of training and knowledge reserve. On the contrary, psychological adjustment transcends physiological response. If extra drugs are used to intervene forcibly, it will be counterproductive and even increase the psychological pressure of candidates.

　　"The value of the college entrance examination lies in the process that we really invest in youth, focusing on the process, not the result. Go all out, have a clear conscience, leave your efforts to yourself, and strive for the best results. " Cheng Yuya said.

　　[Responding to extreme weather] The meteorological department predicts that there is a greater possibility of high temperature in the north and rainfall in the south during the college entrance examination. Candidates should pay attention to heatstroke prevention and cooling, make adequate preparations for extreme weather, choose appropriate travel routes and means of transportation, bring rain gear, reserve enough time on the road, and ask the relevant departments for help in time if there are any problems.

　　Cctv newsThis afternoon, the press center of the 19th National Congress held the sixth press conference, inviting Li Ganjie, Party Secretary and Minister of the Ministry of Environmental Protection, and Yang Weimin, Deputy Director of the Central Financial and Economic Leading Group Office, to introduce the situation of practicing the concept of green development and building a beautiful China, and to answer questions from reporters.

　　Li Ganjie, Party Secretary and Minister of the Ministry of Environmental Protection, summed up the achievements of ecological civilization construction since the 18th National Congress with five "unprecedented":

　　First, the level of ideological understanding is unprecedented.The consciousness and initiative of the whole party and the whole country to implement the concept of green development have been significantly enhanced, and the situation of neglecting ecological environment protection has changed significantly.

　　Second, the intensity of pollution control is unprecedented.Three "Ten Articles" were issued and implemented, namely, three major action plans for air, water and soil pollution prevention and control, and we resolutely declared war on pollution. The construction of environmental infrastructure such as sewage and garbage disposal has been accelerated.

　　Third, the frequency of system introduction is unprecedented.The central leading group for comprehensive deepening reform deliberated and adopted more than 40 specific reform plans for ecological civilization and ecological environment protection.

　　Fourth, the scale of supervision and law enforcement is unprecedented.Many laws, such as the Environmental Protection Law, the Air Pollution Prevention Law, the Water Pollution Prevention Law, the Environmental Impact Assessment Law, the Environmental Protection Tax Law, and the Nuclear Safety Law, have been revised, and the soil pollution prevention law has entered the legislative review process in the National People’s Congress Standing Committee (NPCSC).

　　Fifth, the speed of environmental quality improvement is unprecedented.In 2016, the three major regions — — The average concentration of fine particulate matter in Beijing-Tianjin-Hebei, Yangtze River Delta and Pearl River Delta regions, that is, the average concentration of PM2.5, has dropped by more than 30% compared with that in 2013, when Atmosphere Ten was formulated. The proportion of acid rain area in China’s land area has dropped from about 30% at the historical high point to 7.2% last year.

　　The report of the 19th National Congress of the Communist Party of China has set new goals for the construction of ecological civilization and the protection of ecological environment. Li Ganjie, Party Secretary and Minister of the Ministry of Environmental Protection, also introduced this at the press conference:

At the same time, it will also carry out targeted "point-and-click" inspections.

　　Do a good job in forecasting and early warning from "fighting the blue sky defense war" to "winning the blue sky defense war"

　　At the press conference, Li Ganjie, Party Secretary and Minister of the Ministry of Environmental Protection, also introduced the achievements made in air pollution control since the release of "Atmosphere Ten":

　　When answering a question about air pollution control, Li Ganjie said that it is necessary to make predictions and early warnings to win the blue sky defense war.

　　Li Ganjie, Party Secretary and Minister of the Ministry of Environmental Protection:

　　First of all, we should do a good job in forecasting and early warning. First, we must understand the situation of pollution discharge; The second is to clarify the meteorological conditions. Every day, especially after autumn and winter, experts from our meteorological department and environmental protection department have a mechanism to sit together and analyze and give full play to their respective specialties.

　　In the report of the 19th National Congress of the Communist Party of China, the General Secretary proposed to continue to implement air pollution prevention and control actions and win the blue sky defense war.

Beijing, China, November 30 (Reporter Lei Yan) Recently, it has been said that drinking pure water for a long time will lead to calcium deficiency, acid constitution and decreased immunity. Is that really the case? The scientific gossip list guided by Beijing Science and Technology Association, Beijing Municipal Committee Network Information Office and Capital Internet Association gives the truth.

Purified water is treated by many complicated processes, and there are almost no impurities such as minerals and microorganisms in it. But because it is too pure, many people worry that it is not good for their health.

This paper introduces that drinking pure water for a long time will not lack minerals, and will not get rickets. The minerals of human body are mainly supplied by food, and the elements such as calcium and magnesium in fruits, vegetables, meat and grains are very rich. Nutrition can be guaranteed as long as the daily diet is balanced.

In addition, drinking pure water will not make the body fluid sour, because the human body has a powerful acid-base balance adjustment system, and respiratory, urinary and body fluid buffer substances will take care of everything. Pure water is neutral, so don’t worry about it unless there are special circumstances such as severe kidney disease.

Drinking pure water will not lead to nutrient loss and reduce immunity. Immunity depends on heredity, lifestyle, exercise and vaccine. Purified water removes harmful substances, but it also reduces the risk of disease caused by drinking water. Whether it is pure water or mineral water, you can safely drink it as long as it meets the national standards.

The Consumer Council of Fujian Province conducted a comparative test on 59 types of coffee made and sold in 20 coffee sales units in Fuzhou, and all of them detected low levels of Class 2A carcinogens. The samples involved Ruixing and Starbucks …

Seeing this "deadly" news

How many people are like Xiaobian?

Immediately put down his hand.

Coffee used to "prolong life" …

However, there is a famous saying in the "scientific community"

"Leaving the dose to say that toxicity is hooliganism"

Why don’t you have a cup of coffee to refresh yourself

Take a closer look at the news

What the hell is going on?

Partial sampling sample

In this comparative experiment, 59 types of ready-made coffee sold in 20 coffee sales units in Fuzhou were sampled (including 30 offline and 29 online). The samples involved 20 mainstream brands in the market, including American coffee, latte and flavor latte, which basically covered the ready-made coffee products sold in the market.

In this comparative experiment, eight items, such as energy, carbohydrate, protein, fat, trans fatty acid, total sugar, caffeine and acrylamide, were tested. Judging from the results of this test:

No trans fatty acids were detected in the 1.59 samples (below the detection limit of 0.0013g/100g).

2. In the detection of protein, fat and other items, the detection amount of most products is stable, which basically meets the requirements of national healthy diet recommendation, and the quality of milk and dairy products added in coffee is good.

3. In the testing items of energy, sugar, caffeine, acrylamide, etc., the testing results of each product are quite different, which is worth studying and discussing and paying attention to by consumers.

Among the 59 samples, the energy test results are high and low, and the energy of a cup of coffee is higher than 1/6 of the energy needed by an adult woman in a day; There are two kinds of American coffee and two kinds of lattes labeled as "sugar-free" in the samples, but after testing, the sugar content of two kinds of lattes exceeds the maximum limit stipulated by the standard for "sugar-free"; Caffeine detection showed that the caffeine content of four samples was less than 200mg/kg, which was slightly inferior in refreshing effect.

It is worth noting that

In this 59 samples,

Low levels of class 2A carcinogens were detected.

"acrylamide"

At present, China has not been interested in coffee

Acrylamide has restrictive or prohibitive provisions.

Then acrylamide

What exactly is it?

Can acrylamide cause cancer?

Acrylamide is mainly produced in the process of high temperature treatment of some foods. In 2002, it was first reported by Swedish researchers that a large amount of acrylamide would be produced in fried or baked food. Acrylamide content in food is influenced by many factors.

Food (especially plant food rich in carbohydrates and low in protein) will be naturally produced in large quantities under the cooking condition of > 120℃, which is less produced when boiled with water, and the content in uncooked food is very low.

Among the four kinds of carcinogens published by the World Health Organization, acrylamide belongs to Class 2A carcinogen, which means that there is limited evidence of carcinogenicity to human beings. Many epidemiological studies have shown that acrylamide is related to kidney cancer, endometrial cancer and head and neck tumors, but these carcinogenicity are only "suspected".

According to a research result of International Journal of Food and Chemical Toxicology (No.48) in 2010, the dose of acrylamide causing cancer is 2.6~16μg/kg.day(1 microgram is one millionth of 1 gram), that is, if an adult weighing 60 kilograms ingests 156 micrograms of acrylamide every day (156 micrograms = 2.

Make coffee according to the rules.

The average content of acrylamide is

13μg/kg for conversion.

That is to say, you need to drink 12kg of coffee every day.

To drink a carcinogenic dose

We can really do it every day

Have you finished drinking 12kg of coffee?

The answer is not scary.

But properly control the intake of harmful substances.

It is always right!

In view of the results of this comparative test, the Consumer Council of Fujian Province and the Consumer Council of Fuzhou City issued a consumption reminder to remind consumers that the freshly made and sold coffee tastes mellow and rich, but it is not suitable to drink more, so it should be drunk scientifically and reasonably. Pay attention to the following points when buying ready-made coffee:

First, consumers should learn some basic coffee knowledge before consuming coffee, such as the classification and differences of common coffee (such as American coffee, cappuccino, latte, mocha, etc.), understand the differences between Arabica and Robusta coffee beans, and pay attention to the relatively high energy and sugar content of coffee with milk, flavor syrup and other raw materials.

Second, when purchasing coffee, consumers should pay attention to check whether there are any warnings such as sugar and caffeine on the merchant menu or take-away platform options, and choose the appropriate coffee products according to personal tastes and physical conditions. Pregnant women, lactating women, children, adolescents and other sensitive groups should try not to drink or reduce their coffee consumption.

Third, don’t drink too much coffee for a long time. According to the safe intake of caffeine per day, it is not more than 400mg, generally 1 to 2 cups per day, which is safer. At the same time, coffee contains caffeine, oxalic acid and other substances. Excessive drinking will affect the absorption of calcium, increase the risk of osteoporosis, make people excited for a long time, insomnia, anxiety, and even cause depression, memory loss and other problems.

Fourth, develop a correct way to drink coffee. Usually, the water temperature of drinking coffee should be well controlled, and it is best not to exceed 65 degrees, otherwise it will affect the oral mucosa, gastrointestinal mucosa and even cause mucosal damage. Pay attention to the time of drinking coffee, try to choose after meals, and avoid drinking coffee before going to bed at night or on an empty stomach in the morning. It is not advisable to drink coffee after drinking. People will enter a state of high spirits after drinking. If they drink coffee again, it will only aggravate the excited state of the human body and do great harm to human organs.

    Original title: Jiangsu colleges and universities welcome new students one after another, and the class of 2024 "Meng Xin" opens a new journey-

    University, here we come!

    On August 24th, more than 4,000 freshmen from all over the world became "Dongda people". Photo by Li Liu

    Since August 23, many universities in Jiangsu have ushered in the "Meng Xin" in 2024. The old campus with rich background and the new campus with new appearance are full of vitality. When the freshmen step into the campus with their bags and longings, at this moment, it is both a dream come true and a new beginning.

    Go to your alma mater together, and strive for youth to meet here.

    What’s it like to be alumni with mom and dad? At the scene, some new students visited the campus with their parents who had studied and lived in the same school.

    "My father is more familiar with the Gulou Campus than I am. I live in Room 2 of Taoyuan, and he lived in Room 12 of Nanyuan." On the morning of 24th, in the Gulou Campus of Nanjing University, Ruiqi Luo from Korla, Xinjiang, took a walk with his father on campus as soon as he cleaned up his dormitory. "My father is a Nantah native. He has been telling me about Nantah since he was in primary school. Since then, I have had the desire to apply for NTU. " When volunteering, Ruiqi Luo chose NTU Intelligent System Integration Experimental Class without hesitation. In 1990, after graduating from the School of Earth Science and Engineering of Nanjing University, Luo Dad chose to return to Xinjiang to join the construction of the western region. After returning to his alma mater many years later, Mr. Luo and his son "searched for roots" in the Gulou campus. "I am in the northwest and my heart is in Nantah. I hope that children can study hard in Nantah and become pillars of society! "

    "This is Dongda Auditorium, which is the former Institute of Technology. We used to study in the evening here …" On the 24th, Hu Yonghua, who returned to her alma mater, introduced her daughter Hu Xiaoyu incessantly. He and his wife Zhu Ping are both alumni of Southeast University, and their daughter was admitted to the "English+Information Engineering" double-degree major this year. Coincidentally, Xu Jingheng, who studied in Nanjing No.29 Middle School with Hu Xiaoyu, was also admitted to this major, while Jamlom’s parents were alumni of Southeast University majoring in management science and engineering and regional economics in 2002.

    Returning to the campus with the children again, Xu Jingheng’s parents also recalled the lush years of that year. "At that time, I lived in Room 9, Wenchang, Sipailou Campus, and my wife’s dormitory was behind Liuyuan Hotel. At that time, I rode my bike from east to west with egg cakes to bring her breakfast every day …" Xu Dad said, smiling hard on his face. Xu Jingheng, who grew up listening to the "omelet story", designated Dongda as an ideal university in his freshman year of high school and kept fighting for it. "What touches me most is the unique cultural atmosphere of Dongda University. I hope to make more friends here and become a better self." Xu Jingheng said.

    Go back to the old campus to "seek roots" and go to the new campus to dream.

    Since Nanjing University started its "root-seeking school" in 2022, all the freshmen in the school have stayed in Gulou Campus. In Southeast University, 2,340 freshmen moved into the Sipailou campus this year, which is the first time in recent years that more than half of the freshmen reported to the campus.

    "Walking into the campus of Dongda University, walking into Wutong Avenue, what comes to my face is the profound cultural heritage!" "Have long heard of Neusoft Meian, finally saw it today. I hope that in the future, I can also’ chew the roots and do great things’. " During the welcome period, Southeast University opened the school history museum, Mei ‘an and Wu Jianxiong Memorial Hall, and carried out campus visits to let freshmen feel the cultural atmosphere of the 120 universities in the process of searching for the source. In front of Yongquanchi, the landmark building auditorium of Dongda University, the school also organized the activity of "Freshmen Parents Say". At the scene, freshmen and parents took the stage to express their wishes and hopes and cheer for a better future together. During the activity, freshmen also wrote a wish card "to themselves after four years" and sealed it for graduation.

    "Root-seeking" and "dream" are the key words on the day of registration. "We have noticed that many freshmen have special feelings for the Gulou Campus of Nantah. For example, Yang Zehao of Kaijia College, the first thing he did after reporting for the freshman training camp on August 19, was to punch in again with his photo taken with Peking University Building when he was 9 years old, thanking him for his fate with Nantah." Shi Jiahuan, deputy secretary of the Party Committee of NTU Freshmen College, told the reporter that the first year of college is a crucial period for freshmen to know the university, enter the discipline and start the future. Nanjing University has launched micro-resources for freshmen’s adaptive education, so that students can better integrate into the university, the city and the times. "Freshmen will set up their growth goals, understand the charm of the subject and find the right direction of their interests through the study of topics such as’ University and Mr. Da’,’ Adaptive Education for Freshmen’ and’ Yuhua Hong-the Power of Faith’." Shi Jiahuan said.

    In the brand-new Jiangnan University Jiangyin Xiakewan Campus, the first batch of 455 "Meng Xin" settled in. Simple architectural style and water landscape with Jiangnan flavor are in the same strain as those of Jiangnan University Headquarters and Yixing Graduate School, and various banners and signs welcoming new students can be seen everywhere. Freshmen of the School of Digital Technology and Creative Design also got many "small surprises"-from brand-new visual image design and visual expression based on college English abbreviations, to specially customized canvas bags and card sets, hand-drawn maps of Xiakewan Campus in Jiangyin, and to white paper fans that can be stamped, all of which reflect the sincerity and ingenuity of the college. "This university’ meeting ceremony’ is so interesting. I will study hard and hope to have my own design works in the future." Ding Wei, a freshman majoring in digital media art, said.

    Start new courses for new majors and cultivate new talents.

    The reporter learned that most of the freshmen in 2024 were born in 2006, and Southeast University welcomed the post-10 students.

    At the welcome scene of Dongda University, a 13-member "Xueba Group" attracted much attention. Tan Ruiqi from Fushun No.2 Middle School in Liaoning Province was the youngest of them. After three years in elementary school, two years in junior high school and two years in senior high school, Tan Ruiqi, who is only 14 years old, is the first post-10 s student in the history of Dongda University. "Learning itself is a very interesting thing. I enjoy every process of exploring the unknown, so I chose to take the college entrance examination in my second year of high school and want to invest the saved time in more creative university study." Tan Ruiqi said that when I was in primary school, portraits of scientists Qian Sanqiang and Li Siguang hung in the classroom, and I was moved after learning about their deeds. "I hope I can serve my country like them and be a useful person."

    When I first entered the campus, the dream of serving the country through science and technology was already in my heart. Just entering the Intelligent Manufacturing College of Jiangnan University (Junyuan College), freshman Song Zihan saw the robot that greeted them. "I liked robots very much when I was a child, and now I am very interested in new terms such as drones and autonomous driving. The Yangtze River Delta has a strong science and technology atmosphere, and I hope that I can also participate in the production of advanced robots in the future. "

    In order to cultivate future-oriented talents with new quality, many colleges and universities have implemented new training plans in the new semester. This autumn semester, the core course of artificial intelligence general education in Nanjing University, which has received much attention, officially set sail. The course is oriented to all freshmen, and through the knowledge system and training mode of deep integration of AI and various disciplines, AI literacy education is integrated into the training of top-notch innovative talents to help cultivate and develop new quality productivity. Southeast University has also created an action plan of "Artificial Intelligence+Education" for freshmen. Led by the Institute of Artificial Intelligence, the course of "Introduction to General Studies of Artificial Intelligence" has been built according to the categories of science, engineering, medicine and humanities, and an interdisciplinary virtual teaching and research section has been set up to serve the whole school’s "Artificial Intelligence +X" education, with 105 pilot projects.

    In Jiangnan University, the first four colleges that settled in Jiangyin Xiakewan Campus were officially unveiled on June 7 this year, further connecting industrial transformation and local economic development. Cao Ming, dean of the School of Digital Technology and Creative Design of the school, said that in order to meet the new needs of the industry, the design discipline of the school is being adjusted around intelligent technology and intelligent interaction. "For example, the curriculum design of digital media art majors is more inclined to interactive media and virtual interaction. Fashion design majors integrate smart wearable devices into teaching. In the overall curriculum system, the college will also join artificial intelligence courses for freshmen. " (Yang Pinping, Xie Shihan, Ye Zhen)
