CCTV News:Recently, the United States has continued to increase its military deployment in the surrounding areas of Iran. The British "Guardian" conducted a rough statistics a few days ago, showing that there are currently more than 50,000 US troops deployed around Iran.

According to the Guardian, the current US military deployment in the Middle East is: 2,500 in Turkey, 5,100 in Iraq, 1,500 in Jordan, 15,000 in Kuwait, 7,000 in Bahrain, 11,000 in Qatar, 2,500 in Saudi Arabia, 5,000 in United Arab Emirates, 4,000 in Djibouti and 200 in Oman, with a total of nearly 54,000. At the same time, the "Lincoln" aircraft carrier battle group and B-52 bombers were also dispatched to the Persian Gulf.

Some analysts believe that the main purpose of the United States at present is to attack the Iranian economy through military deterrence and severe sanctions, incite the dissatisfaction of the Iranian people, and put pressure on the Iranian government. Therefore, the possibility of a war is not great.

Rouhani made a tough voice: resistance is the only choice.

Recently, the situation in the United States and Iraq has suddenly become tense because the United States lifted the sanctions exemption for eight Iranian crude oil importers.

According to CNN, the Iranian side believes that the current position of the US government on bilateral relations is "crazy" and "chaotic". On the evening of 19th, US President Trump sent a message on social platforms threatening Iran, saying that if Iran wanted to fight, it would be the official end of Iran. But then the U.S. government changed its attitude, saying that any provocative act by Iran would encounter "powerful forces", but the United States was also willing to negotiate with Iran.

According to Sputnik news agency & radio, citing the Iranian National News Agency, in response to the US remarks, Rouhani stated on the evening of 20th that all Iranian officials had reached a consensus and would stubbornly resist the US sanctions policy.

Rouhani said: "If we quit the Iranian nuclear deal just because of the provocative behavior of the United States, the United Nations and the whole world will impose sanctions on us, except the United States. I support negotiation channels and diplomatic means, but I will not accept it under the current situation. The current situation is not suitable for negotiation. We only have one choice, and that is resistance. "

Ultimate poster

1905 movie network news The annual "5.20" Valentine’s Day is the advertising day of the network fire. Today, the super sweet youth love movie will be shown in advance in 38 cities across the country, offering a sweet date for the audience three days in advance. At the same time, the film released the ultimate poster of "sugar exceeding the standard". The actors were in the world of macaroon-colored candy, and the girl’s heart was bursting with sweetness. Continues the comic book’s Secondary 2 style, and the sweet love atmosphere comes to my face.

Aspect 1: Super youth lineup, there are faces and plays waiting for you to see.

The film Strange Classmate Next Door is directed by Sh Tsukikawa and co-starred by popular Japanese actors Suda Masaki, Tao Tsuchiya, Yuki Furukawa, Yamata Yuki, Ikeda Elaiza and Hamabe Minami. Suda Masaki just won the Japanese Film Academy Award for Best Actor at the beginning of the year, which can be described as the coexistence of strength and face value. As his second film to appear on the big screen in China, and the last time he wore a student uniform, it aroused the crazy expectations of fans. Actress Tao Tsuchiya, who is known as the "Goddess Harvester", is deeply rooted in people’s hearts with her sweet and lovely image. This time, she will "harvest" the goddess soda again, which will form the most "Too Sweet CP" with Suda Masaki in history.

In addition, the audience will also see Suda Masaki and two Japanese powerful actors, Yuki Furukawa and Yamata Yuki, fighting in the same box and enjoying the experience of "hormone bursting" on the big screen. Ikeda Elaiza, who is known as the new Japanese "Otaku Goddess", and Hamabe Minami, the "Flower of Innocence", will also bring wonderful performances in the film.

Aspect 2: adaptation of high-sugar comics, and no discount will be given to protect the sweetness and the Soviet Union.

The film "Strange Classmate Next Door" is adapted from the Japanese super-popular girl cartoon with the same name. After its release, it was voted as one of the most successful full-action movies of the year. In the original, the feelings between Chun and Yong, which are both exciting and cautious, are very touching. As soon as the news of the real change came out, casting became the focus of IP powder. Suda Masaki’s version of Yoshida Haru has been recognized by everyone in terms of appearance and acting skills. Touching the head, knocking on the ground and dating on the roof … … All kinds of shots restored by gods make fans shout "the second dimension wall is broken, this is the spring and Yong in our hearts". Every role is set with distinctive features. Even a chicken named Nagoya is a "showman".

Aspect 3: Refreshing but not greasy, every love line is easy to knock.

Compared with the movies about campus youth, the movie "Strange Classmate Next Door" continues the comic book’s Secondary 2 style, and the plot is funny without losing the throb of love. A number of love lines are in parallel, and the confession is painful and the refusal is crisp and neat. Represented by the protagonists Yoshida Haru and Mizutani Shizuku, kissing is a way to express love, and confession is also a choice between thoughts. Without those so-called entanglements and helplessness, the expression of feelings in Strange Students Next to Me is direct and pure, refreshing and not greasy. The netizens who have seen it say that this film has cured the long-standing "confession phobia". Every emotional line in the film represents a kind of "love values". No matter whether you are in a state of "unrequited love", "lovelorn love" or "lovelorn love", I believe you can get inspiration from the film.

Aspect 4: geek friends guide, the gospel of social fear syndrome

There are also deep thoughts under the sweetness, and the film also discusses the realistic campus interpersonal relationship, which is comparable to a practical "geek" friend-making guide. In the film, Chun and Yong are both "geeks" in the eyes of students. They represent "unsociable" individuals in campus life, but with each other’s help, they learn to accept the goodwill of others and finally integrate into the collective harvest friendship.

School is like a microcosm of society, and everyone needs to establish good interpersonal relationships during their student days. In this process, people who are not sociable may suffer from difficulties in getting along with others. However, after watching the film, you will know that it may be easier to get happiness by facing your own heart and trying to open your heart and accept others.

The movie "The Strange Classmate Next Door" will be shown nationwide on May 23rd.

　　"This time, the liberalization of competition, the decline in new energy electricity prices is an inevitable trend, and it is very likely to promote a new round of industry reshuffle." On June 2nd, when talking about the newly announced wind power and photovoltaic power generation projects will adopt competitive allocation, giving priority to the construction of projects with low subsidy intensity and large slope retreat, Ningxia industry insiders from China’s first new energy comprehensive demonstration zone and the first pilot area of power auxiliary service market in northwest China said so.

　　The New Deal is bound to affect the investment enthusiasm of enterprises.

　　On May 30th, the National Energy Administration issued the Notice on Matters Related to the Construction of Wind Power and Photovoltaic Power Generation Projects in 2019, clarifying that wind power and photovoltaic power generation projects are divided into two categories: those that do not need state subsidies and those that need state subsidies. On the basis of organizing power grid enterprises to demonstrate and implement the conditions for power transmission and consumption of affordable power grid projects, priority will be given to promoting the construction of affordable power grid projects, and then competitive allocation of projects that need state subsidies will be carried out.

　　The relevant person in charge of the new energy department of the bureau said that the purpose of this move is to improve the competitive allocation mechanism of projects requiring state subsidies and reduce the dependence of industry development on state subsidies. The general orientation of wind power and photovoltaic power generation this year is to "adhere to the general tone of striving for stability, accelerate technological progress and reduce subsidy intensity, coordinate project construction and absorptive capacity, and achieve high-quality development".

　　This policy, known as "the most market-oriented policy in history", marks that the national wind power photovoltaic has entered the bidding era.

　　Since the "Thirteenth Five-Year Plan", the application scale of wind power and photovoltaic power generation in China has been continuously expanded, the technical level has been significantly improved, and the cost has gradually decreased. At the same time, however, the subsidy gap continues to widen, and some areas abandon wind, light and electricity.

　　According to the latest figures, the installed capacity of new energy in Ningxia Power Grid is about 15 million kilowatts, accounting for 49% of the generated electricity and 102% of the electricity load, making it the first provincial power grid in China where the output of wind power and photovoltaic power generation exceeds that of the whole regional network. From 2013 to 2018, the average annual growth rate of wind power installed capacity in Ningxia reached 27%, the average annual growth rate of photovoltaic installed capacity reached 40%, the average annual growth rate of new energy installed capacity reached 32%, and the proportion of new energy installed capacity ranked second in the country.

　　An expert from Ningxia New Energy Research Institute, who did not want to be named, analyzed that the fierce competition of energy investment enterprises is mainly reflected in the competition of on-grid electricity price. As soon as the electricity price drops, the return on investment will also decrease, which will inevitably affect the enthusiasm of enterprises to build photovoltaic power plants. On the other hand, it is reflected in some photovoltaic power generation enterprises, which must invest by selling power stations to digest their production capacity, which also has a great impact on their enthusiasm for building power stations.

　　The main reason is that the price of photovoltaic construction has dropped sharply in recent years, and the investment cost has dropped due to the decline in equipment prices.

　　According to the expert, the initial formation price of 20 yuan was the highest per watt, and last year it was reduced to the lowest value, 1.6 yuan per watt. "This also means that the electricity price has reached a low level. The lowest electricity price in Ningxia in the past two years was 0.55 yuan. Now, if competition is liberalized, it is estimated to reach about 0.35 yuan, which is basically close to parity Internet access." He said frankly.

　　Follow the plan and make active adjustments at the same time.

　　Ningxia is rich in wind energy and solar energy resources. Since it was approved by the National Energy Administration in 2012 as the first comprehensive demonstration zone of new energy in China, the solar material and equipment manufacturing industry has entered a stage of rapid development, and a complete industrial chain including silica, industrial silicon, polysilicon, solar cells and components, solar power stations and so on has been built.

　　According to Ningxia 2015 — Planning of Photovoltaic Park in 2020, Ningxia will invest more than 100 billion yuan in photovoltaic industry in five years, and will take the lead in creating a development model of "park-oriented, intensive and large-scale" new energy projects in the country, and build 10 large-scale photovoltaic parks and related supporting industries through centralized planning.

　　"The biggest dilemma faced by photovoltaic power generation enterprises is that the state subsidized electricity fee is not in place, resulting in a shortage of cash flow. The income from electricity sales by enterprises can only be recovered from the benchmark electricity price, and most subsidies cannot be recovered. " The expert revealed.

　　According to reports, up to now, the state-subsidized electricity fee in Ningxia has only been replenished until March 2017, and the two-year state-subsidized electricity fee has not been put in place, resulting in a very tight cash flow of photovoltaic power generation enterprises, and many enterprises have been forced to transfer.

　　In the face of the introduction of the New Deal, Zhang Yongding, a professor at the School of Business of Yinchuan University of Energy, bluntly said that "it is a catfish effect, which will better play the role of the market in allocating resources". Based on his working experience in enterprises and years of teaching research, he said that the state used financial subsidies and other incentives to increase the proportion of renewable energy in the whole energy structure, but the effect was not very good, and some enterprises did not play their due role with subsidies. The introduction of competition mechanism now is to promote the rapid development of the industry.

　　Wang Linling, an associate researcher at the Institute of Comprehensive Economics of Ningxia Academy of Social Sciences, also believes that enterprises should follow the national strategic planning and make corresponding adjustments in time. But at the same time, he hopes to have a step-by-step adjustment process, so that enterprises can gradually adapt. After all, this policy has a certain impact on the investment enthusiasm of enterprises.

　　"Leading photovoltaic power generation to reduce costs, subsidize and achieve parity has risen to the national strategic level. We will take active measures to deal with and cooperate, and hope that the state can help enterprises get out of the predicament and develop healthily, by going up one flight of stairs." The person in charge of a photovoltaic power generation company in Ningxia said that from its own point of view, it is to strive to reduce the cost per kilowatt; To put it further, it is to strive for Ningxia power grid not to limit electricity, otherwise it will cause great trouble to the "breakthrough" road of photovoltaic power generation.

　　Original title: Century Erqi Factory witnessed the early workers’ movement in China.

The century-old factory area of Erqi Factory has now become the 1897 Science and Technology City of Erqi Factory, providing a brand-new urban living space for the surrounding residents. The picture shows the surrounding residents visiting the exhibition. Photo by Ping Liu

　　In 1897 Kechuang City, Erqi Factory, the former site of the "Erqi" strike in Changxindian, Fengtai District, a special exhibition called "Centennial Follow-up" is going on. Precious exhibits and historical materials, such as the "foreign" railway tracks more than 120 years ago and the payroll of railway workers in Changxindian a hundred years ago, show the vigorous workers’ movement in Changxindian area in the 1920s and the century-long development course of railway construction in China.

　　Eight modern buildings remain in the former site of the "February 27" strike.

　　Walking into the 1897 Kechuang City of Erqi Factory, there are several European-style buildings scattered around the central lawn. The unique triangular mountain flowers and round ventilation window on the gable are unique. These old buildings with a hundred years of history are the modern architectural remains of Erqi Locomotive Factory.

　　The history of Erqi Locomotive Works can be traced back to 1897. As a part of Lubao Railway, the Qing government set up a simple small factory on the north side of the west bank of Lugou Bridge that year-Lugou Bridge Machinery Factory of Lubao Railway. In 1900, under the coercion of western forces, the northern end of Lubao Railway was extended to Qianmen and renamed Jinghan Railway. The original Lugouqiao Machine Factory of Lubao Railway was moved to Changxindian and renamed as "Changxindian Machine Factory of Jinghan Railway". The earliest batch of industrial workers in Beijing was born here, which is one of the birthplaces of modern industry in Beijing, and it has become the starting point and model of combining Marxism with the workers’ movement in China in the changing historical process. Mao Zedong once commented, "The China Workers’ Movement started from Changxindian Railway Factory."

　　In 1966, the factory was renamed as "Beijing Erqi Locomotive and Rolling Stock Factory", which was named after "Erqi" for the first time. Since then, Erqi Factory has continued to operate until it stopped production and transformed in 2018.

　　Today, there are still 8 modern architectural remains in Erqi Factory, including 7 office buildings and 1 production workshop. Among the office buildings, 6 are French style buildings and 1 is Belgian style buildings. As a whole, the building is built with fair-faced brick walls, with two slopes covered with iron tile roofs, modern doors and windows decorated, triangular mountain flowers on the upper part of gables, decorative lines around the feet, and a circular ventilation window in the center. The production workshop is a typical modern workshop building form.

　　These eight modern architectural remains of Erqi Locomotive Works were selected as the seventh batch of "National Key Cultural Relics Protection Units" in 2013, which is one of the former sites of the "Erqi" strike in Changxindian, Fengtai District. After the dismantling of the manufacturing industry of Erqi Locomotive Company in 2018, these modern architectural remains are in an idle state. At present, Fengtai District Cultural and Tourism Bureau has organized and started the structural inspection of cultural relics buildings, and the repair work will be carried out later.

　　Precious historical materials reproduce the railway workers’ movement a hundred years ago

　　In the auditorium of the factory, which was built in 1933, the special exhibition "One Hundred Years of Follow-up" is under way. Entering the special exhibition hall, a train "drives" head-on. This is a set based on the first generation locomotive of "Mao Zedong". The hammer and caliper on the front of the locomotive are the symbols of workers. The ground under the locomotive is covered with glass plates, and there are two rails under the glass plates. These two railway tracks have a lot of origins: one was made in 1896 and the other was made in 1897, when they crossed the ocean to Beijing and were used to build the Lubao Railway.

　　There is a historical photo of Zhang Zhengui in the exhibition, which is the image of Changxindian Railway Station when it was completed in 1899. Mao Zedong, Deng Zhongxia and other revolutionary movements in Changxindian all got off here.

　　In the exhibition, there is also the wage table of Changxindian Locomotive Works at that time, that is, the "salary" list. At that time, the factory was very strict with the management of workers, and implemented a "big week" working system, that is, one day off every two weeks, going to work at 6 am and leaving work at 6 pm every day, excluding lunch breaks. Ordinary workers had to work 11 hours a day, but their wages were only a few cents, and it was difficult for these ordinary workers to get all their wages. However, foreign factory directors and employees work 8 hours a day and take a day off every week, but their wages are several times, dozens of times or even higher than those of workers.

　　At that time, apart from the double oppression and exploitation of imperialism and warlords, the foremen also set up many unreasonable regulations privately, such as fines for drinking water and speaking during working hours, and the foremen used the money exploited by the workers to build houses for the workers to live in collectively, and forced the workers to join in for dinner, which was called "Guo Gang". There are twenty or thirty people to fifty or sixty people in each "pot gang", and at most 70 people live in three rooms. After layers of exploitation, workers get very little salary.

　　Before and after the May 4th Movement, in order to find the knowledge and truth of saving the country and strengthening the country, a large number of aspiring young people went to France to work and study. Why did the preparatory class for studying in France choose to be established in Changxindian? It turns out that Changxindian Railway Factory was built and managed in the French, which has the foundation of learning French and can also provide opportunities for work-study.

　　After the May 4th Movement, railway workers in Changxindian began to accept the influence of new ideas. In March, 1920, Li Dazhao, Deng Zhongxia and others secretly established the Marxist Theory Research Association in Peking University. Shi Wenbin and Ge Shugui, railway workers in Changxindian, were members of the Marxist Theory Research Association. In order to publicize Marxism to workers and awaken their class consciousness, the communist party early organization in Beijing put forward the slogan of "Go among the workers". After the establishment of the Beijing communist party Group at the end of 1920, Li Dazhao sent Deng Zhongxia and others to Changxindian to consult with Shi Wenbin and other workers to organize a labor cram school. Changxindian labor tutorial school is known as the rising place of "Red Star in the North" and has trained a group of backbones for the workers’ movement. In the second half of 1921, Shi Wenbin, Wang Jun and Kang Jingxing joined the Party and became the first batch of workers in Changxindian, party member.

　　The old factory area, which has witnessed the vigorous workers’ movement for a hundred years, has been transformed into a science and technology city with a new format. Under the leadership of the Communist Party of China, China’s railway industry has also developed vigorously, and its independent innovation ability has been continuously enhanced, and it has made one remarkable achievement after another.

　　Transformation of Erqi Old Factory Building Embracing New Business Form

　　The history of Erqi Factory has continued from modern times to this day. The present 1897 Kechuang City of Erqi Factory was transformed from a century-old factory. Walking in the factory, I saw the boring machine turned into a waterfall fountain, the waste industrial iron drum turned into a black-and-white cow, the small crane became a road flag, and the shovel head and valve were painted with different colors to become tropical fish and bouquets.

　　In addition to these amazing landscapes under the arrangement of waste instruments and tools, the whole factory has bid farewell to the old appearance of industrial production and become a brand-new urban living space.

　　Here, we can see a new space with industrial style and fashionable style inside, and Building N16 is one of the representative works. It used to be a factory building with an area of more than 600 square meters and a height of 10 meters. After careful design, it was transformed into a three-story space with a usable area of more than 1,200 square meters. It has a large-scale ladder "classroom" that can accommodate more than 120 people at the same time, a shared reading area, and a multi-functional conference room, office and living room that can accommodate 30 to 100 people.

　　Factory buildings have been transformed into incubators, cultural and creative spaces, restaurants and bars, children’s entertainment spaces and shopping spaces, enriching people’s lives in Changxindian and even the west bank of Fengtai section of Yongding River. The 1897 Science and Technology Innovation City of Erqi Factory has injected a strong vitality into Changxindian and led a new way of regional development. (Sun Ying)

　　Efficacy and function of green teaDrinking green tea often has many benefits. According to the latest report of British "Reuters News Network", a large-scale new Japanese study published in American Journal of Clinical Nutrition found that the elderly who often drink green tea are more flexible and independent than other elderly people. The effects and functions of green tea are as follows:

　　1. Sun protection

　　Recently, a study in the United States pointed out that catechins in green tea have a strong antioxidant function. After skin care products containing green tea are applied to the skin, even if they are exposed to the hot sun, the peroxides that cause sunburn, relaxation and roughness of the skin can be reduced by about 1/3. This proves that the ingredients in green tea have sunscreen function.

　　2. Radiation protection

　　For the busy people, the easiest way to resist computer radiation is to drink 2 ~ 3 cups of green tea and eat an orange every morning. Because tea is rich in provitamin A, it can be quickly converted into vitamin A after being absorbed by the human body. Vitamin a can synthesize rhodopsin, which can makeeyeYou can see things better in dim light. Therefore, green tea can not only eliminate computer radiation, but also protect and improve eyesight.

　　3. Reduce blood fat

　　Drinking tea can reduce blood lipids and cholesterol, and make the body lighter. This is because of the comprehensive coordination of phenolic derivatives, aromatic substances, amino acids and vitamins in tea, especially the comprehensive effect of tea polyphenols, theanine and vitamin C, which can promote fat oxidation, help digestion, reduce fat and lose weight.

　　4. Anti-halitosis

　　Green tea contains fluorine, in which catechin can inhibit the action of cariogenic bacteria and reduce the occurrence of dental plaque and periodontitis. Tannic acid contained in tea has bactericidal effect, which can prevent food scraps from breeding bacteria, so it can effectively prevent bad breath.

　　5. Anti-aging

　　Antioxidants contained in green tea help to resist aging. Because of the process of human metabolism, if it is over-oxidized, it will produce a lot of free radicals, which will easily age and cause cell injury. SOD (Superoxide Dismutation) is a free radical scavenger, which can effectively remove excess free radicals and prevent the damage of free radicals to human body. Catechins in green tea can significantly improve SOD activity and scavenge free radicals.

　　6, antibacterial

　　Studies have shown that catechins in green tea can inhibit some bacteria that cause human diseases, and at the same time, it will not harm the proliferation of beneficial bacteria in the intestine, so green tea has the function of whole intestine. Studies have shown that tea polyphenols can eliminate excessive harmful free radicals in the body, and can regenerate efficient antioxidant substances such as α-VE, VC, GSH and SOD in the human body, thus protecting and repairing the antioxidant system, which has significant effects on enhancing the body’s immunity, preventing cancer and preventing aging.

　　7, prevent stomach trouble

　　A study shows that drinking more green tea can prevent chronic gastritis and gastric cancer. The study found that the longer people drink green tea, the lower the rate of chronic gastritis and gastric cancer, and the rate of gastric cancer of people who love green tea is 48% lower than that of people who don’t like tea.

　　8. Cancer prevention

　　Green tea can inhibit some cancers, but its principle is limited to the inference stage. Drinking more tea is bound to have a positive encouraging effect on preventing the occurrence of cancer.

　　9. Promote digestion

　　Recent research reports show that green tea can help improve indigestion, such as acute diarrhea caused by bacteria, and drinking a little green tea can alleviate the condition.

　　Experts specially remind: the fresher the tea, the better. Nutritionally speaking, the nutrients of the freshest tea are not necessarily the best, because the so-called new tea refers to the tea that has been picked for less than a month. Because these tea leaves have not been placed for a period of time, some substances that have adverse effects on the body, such as polyphenols, alcohols and aldehydes, have not been completely oxidized. If you drink new tea for a long time, you may have uncomfortable reactions such as diarrhea and abdominal distension.

There are four electrochemical directions, namely, seawater electrolysis catalyst, electrocatalytic nitrate reduction to synthesize ammonia, anion exchange membrane fuel cell and electrocatalytic synthesis of hydrogen peroxide. There are three directions of nano-materials, namely high entropy alloy catalyst, quantum dot light emitting diode and two-dimensional transistor. There are two directions in organic chemistry, namely artificial molecular machines and supramolecular adhesives. There is one emerging cross direction, which is mechanochemistry. Among them, artificial molecular machines and mechanochemistry were selected as the Top10 hot spots for the second time.

In the field of chemistry and materials science, there are two research projects, both of which are related to energy conversion and storage. "Development of high-performance HER and ORR photocatalyst and its application in solar fuel synthesis" mainly involves the conversion of solar energy into green fuels such as hydrogen and hydrogen peroxide by hydrogen reduction reaction (HER) and oxygen reduction reaction (ORR) using photocatalysts, such as covalent organic framework compounds and metal oxide semiconductors (mainly BiVO4). The preparation of polymer dielectric capacitor mainly involves using polymer as the dielectric of capacitor, adjusting its composition and structure, and improving the energy density and discharge efficiency of capacitor at the same time.
