On April 17th, the reporter learned from the FAST Operation and Development Center of the National Astronomical Observatory that more than 900 new pulsars have been discovered by the 500-meter spherical radio telescope (FAST) known as the "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)".

　　Produce a series of world-class achievements in the fields of the origin of fast radio bursts and gravitational wave detection; Independent research and development of receiver core components is expected to go abroad; FAST core array construction is ready to go … …

　　Staring at the starry sky, I kept walking. "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" is constantly providing China wisdom to the world astronomy and China technology to the global engineering community.

　　Frequent achievements

　　"Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" is a well-known national weapon. In order to "produce early results, produce more results, produce good results and produce great results", China scientists constantly "challenge the limits of cognition and technology" and polish their profound "eyes" with "Creation by China".

On April 17th, the reporter got news from the FAST Operation and Development Center of the National Astronomical Observatory of the Chinese Academy of Sciences that the number of new pulsars discovered by the 500-meter spherical radio telescope (FAST), known as the "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)", exceeded 900. Xinhua News Agency issued Liu Xu Lu Yuhan’s establishment

　　Up to now, Five-hundred-meter Aperture Spherical Radio Telescope (FAST) has discovered more than 900 new pulsars, including at least 170 millisecond pulsars, 120 binary pulsars and 80 faint occasional pulsars.

　　"We are expanding the cognitive limits of human beings to the universe." Han Jinlin, head of the galactic plane Pulsar Survey Project of the National Astronomical Observatory, said. In the 50 years from the discovery of the first pulsar by humans to the discovery of the first pulsar by FAST, less than 3,000 pulsars have been discovered in the world.

　　On October 10th, 2017, Five-hundred-meter Aperture Spherical Radio Telescope (FAST) announced the discovery of six new pulsars, achieving a "zero breakthrough". This is the first time that China has discovered pulsars with its own independently developed radio telescope.

　　At present, more than 900 new pulsars have been discovered by Five-hundred-meter Aperture Spherical Radio Telescope (FAST), which is more than three times the total number of pulsars discovered by other telescopes at the same time in the world.

　　Among them, compared with the normal pulsars, the radiation flux density of 80 faint occasional pulsars is one order of magnitude lower, and the lowest one has reached the submicrocentric order.

　　In Han Jinlin’s view, the study of these accidental pulsars is of great significance for understanding how many dense neutron star wrecks are formed after the death of stars in the Milky Way and revealing the unknown physical process of pulse radiation.

　　Han Jinlin told reporters that if searching for pulsars is compared to picking fruits, all the pulsars discovered before are close to the ground and easy to "pick", while the more than 900 new pulsars discovered by Five-hundred-meter Aperture Spherical Radio Telescope (FAST) are farther away or more difficult to pick.

　　Because each pulsar has its own special pulse and stable rotation frequency, they are equivalent to the "lighthouse" with unique signal marks in the universe. If the Interstellar can be realized in the future, these pulsars will provide "navigation" for human beings to travel in the vast universe.

　　"We accurately measure the coordinates of pulsars in space, and monitor the phases and corresponding positional relationships of multiple pulsar signals during the journey, so that humans will not get lost in interstellar travel." Han Jinlin said.

　　It is the first time to observe the "pulse" of black hole in radio band, detect the key evidence of the existence of nanohertz gravitational wave, and detect and construct the world’s largest neutral hydrogen galaxy sample … … In recent years, "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" has made China contributions to exploring the mysteries of the universe.

　　In the face of the unknown and the future, human destiny is shared. From the moment it was born, "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" shouldered the mission.

　　Sun Chun, the measurement and control engineer of Five-hundred-meter Aperture Spherical Radio Telescope (FAST), introduced that since it was officially opened to the global scientific community on March 31st, 2021, Five-hundred-meter Aperture Spherical Radio Telescope (FAST) has helped research teams from 15 countries including the United States, the Netherlands and Australia to carry out observation for nearly 900 hours, covering many fields such as scientific target drift scanning survey, neutral hydrogen galaxy survey, galaxy polarization survey, pulsar time measurement, and rapid radio burst observation.

　　In the foreseeable future, "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" will bring more new perspectives for the international astronomical community to continue to explore the universe and try to find the unknown, and make greater contributions to leading mankind to break through the new field of cognition.

　　Innovation is not limited.

　　"I thought it would be revised seven or eight times, but I didn’t expect the performance of the first edition to reach the world advanced level." Chai Xiaoming, a senior engineer at the National Astronomical Observatory of the Chinese Academy of Sciences, introduced to the reporter a low-noise amplifier with a silver-plated shell and only the size of an organ. It was hard to hide his excitement in his speech.

　　Low noise amplifier is the core component of Five-hundred-meter Aperture Spherical Radio Telescope (FAST) receiver, which was imported before.

　　In order to solve the problem of "stuck neck" and master the key technology in their own hands, Chai Xiaoming’s team spent nearly two years independently developing this high-performance domestic low-noise amplifier.

　　Once the prototype was launched, it attracted the attention of the international astronomical community. The BINGO project in Brazil first proposed the willingness to cooperate in bulk purchase to the FAST Operation and Development Center.

　　As the largest and most sensitive single-aperture spherical radio telescope in the world, "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" has stimulated many special technical requirements, which requires China scientists to give full play to their subjective initiative and creativity, and to optimize and upgrade by constantly "challenging the cognitive and technical limits" and constantly "discovering and solving problems".

　　There is no shortcut to innovation, only dare to climb.

　　"No one told you what to do, and no one was sure that his own method would work." Jiang Peng, executive deputy director and chief engineer of FAST Operation and Development Center, said that the difficult research of "trial and error, failure and courage" runs through almost every link of FAST construction stage.

　　In order to solve the problem of cable fatigue, Jiang Peng led a group of young people through nearly 100 failures and successfully supported the "retina" of "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)".

　　In order to develop a new control system, Sun Jinghai, director of the Measurement and Control Engineering Department of FAST Operation and Development Center, burned the midnight oil to the east for countless times and almost rewritten all the core algorithm codes.

　　In order to solve the problem of electromagnetic interference in substations, Gan Hengqian, director of the Electronic and Electrical Engineering Department of FAST Operation and Development Center, invented &hellip, a high-voltage filter matching with Five-hundred-meter Aperture Spherical Radio Telescope (FAST), after nearly two years of exploration and testing. …

　　Only in the construction stage, "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" won important scientific and technological awards in more than ten fields, such as steel structure, automation industry, machinery industry, surveying and mapping geographic information technology, and electromagnetic compatibility research and development.

　　"Eye of the Sky" asks the sky, and there is no end. Jiang Peng said frankly that if FAST is only regarded as a telescope and a monitoring device, it has reached the standard now. However, to maintain the leading position of FAST in the world, our innovation cannot stop, and we will do our best to make FAST more stable and efficient.

　　At present, the annual observation time of FAST is stable at about 5,300 hours, which plays an important supporting role in continuously outputting scientific research results.

　　Compete for the future

　　Explore the sky and decipher the stars. "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" has never stopped innovating.

　　"Astronomy is extremely romantic, because it studies the sea of stars of human beings. Astronomy is also extremely cruel, because international competition is extremely fierce, and once it is relaxed, it will lose its leading position. " Jiang Peng said.

　　Looking around the world, many radio telescope arrays, such as SKA, are under construction.

　　"Once these telescopes are put into operation, ‘ Five-hundred-meter Aperture Spherical Radio Telescope (FAST) ’ Will face enormous challenges. " Jiang Peng said, "If we relax a little, China astronomers may ‘ Lost ’ The forefront of the radio band field of vision. "

　　The reporter recently walked into the core area of "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" and saw on a hill less than 3 kilometers away from "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" that the excavator was working intensively, and the original jagged hill top with miscellaneous trees had been leveled and compacted.

　　"We plan to use the excellent electromagnetic wave environment within 5 kilometers around FAST in the next five years to build 20 to 30 fully movable radio telescopes with a diameter of 40 meters, and form a comprehensive aperture array with FAST, that is, the FAST core array." Jiang Peng told reporters that a 40-meter-class fully movable radio telescope will be built on the working hill within this year.

　　"By ‘ Five-hundred-meter Aperture Spherical Radio Telescope (FAST) ’ Observing the universe is like using ‘ Thick-headed pencil ’ If the core array is completed and put into use, it is equivalent to using high-resolution ‘ Digital camera ’ Shoot the distant stars. " Jiang Peng introduced that once the core array is completed, it will greatly improve the vision of "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" and let "‘ Five-hundred-meter Aperture Spherical Radio Telescope (FAST) ’ Not only can you see far, but you can also see clearly. "

　　【Pacific auto network tire channel】 This issue of Xiaobian will introduce you to sports tires. The biggest feature of sports tires is high performance and excellent handling performance. There are many sports tires on the market, and the more choices car owners face when changing tires, the more tangled they tend to be. The average car owner will buy according to several aspects: brand, price, original tires and friends’ introduction, etc. These are good methods, but the most important thing is that the car mainly knows the tires and knows what kind of tires to choose. Therefore, Xiaobian will introduce the mainstream representative sports tires on the market, so that everyone can understand them first and then make a choice.　　

　 　In order to facilitate your reading, please first understand the following parameters:

　　Hub diameterAlso called rim diameter, it refers to the size of the tire suitable for mounting on the hub.load index, refers to the maximum upper limit load of the tire.speed, refers to the maximum upper limit speed of the tire.figure, refers to the structure of tread grain, mainly including symmetry, asymmetry and single direction.abrasionindex, is the main measure of tire tread wear performance and service life of the logo, the higher the score, the more wear-resistant.Traction index, which is a measure of the adhesion between tires and the ground, is divided into four levels: AA, A, B and C, with AA being the highest.Heat generation index, is the ability of tire to resist heat generation, which is related to the high-speed performance of tire. It is divided into three levels: A, B and C, with A being the best. (Please click for more details.This > > >)

　　　 What is a sports tire? Sports Performance The tread groove of the tire is relatively wide and the tread blocks are relatively large, in order to have good drainage performance and strong grip on the ground, but this kind of tire has obvious shortcomings, such as loud noise and poor comfort. Sports tires and comfortable tires are two extremes. To pursue the sports performance of tires, we must give up the comfort performance, and vice versa. However, there are also some tires that can achieve comfortable and well-balanced movement, such as Pirelli’s P Zero Rosso and Goodyear Sanneng.

Compact, medium-sized and medium-sized cars suitable for 16-20-inch wheels: 800-2060 yuan.

　　　　Goodyear Eagle F1 Directional 5 is a tire with single tread pattern. The tread integrates three technologies: central annular rib, fully enclosed shoulder and polymer formula. This is Goodyear’s SportGrip technology. The central annular rib improves the steering response ability; Shoulders on both sides are fully enclosed to reduce the noise generated by the tire during driving; The optimized tire carcass section increases the ground contact area, and finally improves the grip. This design not only improves the grip, but also reduces the noise, killing two birds with one stone.

　　According to the test, D5′ s lateral grip is stronger than D3′ s, and its handling response is better when changing lines, and there will be no tire ringing or slipping for a long time when hitting the direction at a fast and large angle. This is mainly due to the design of the four main drainage grooves of the tread (to improve the drainage capacity) and the central annular rib (to improve the response ability of line change).

　　　　 D5′ s wear index is 300, which is not too high or too low. For an active high-performance sports tire, it’s ok. One thing we should pay attention to, D5 is a tire with a single guide pattern. What does this mean? When installing, it is necessary to clearly distinguish the direction from the inside and outside, and it is also very troublesome to choose the spare tire. It can only be installed on one side, and another time, we must find another way. Its wheels have five specifications of 16-20 inches, which are mainly suitable for compact, medium-sized and medium-sized cars.

　　Pilot Sport 3(PS3) is a Michelin tire with high performance and strong handling, which pays more attention to driving pleasure and handling performance. PS3 can make the vehicle achieve the effects of stable acceleration, high-speed cornering and shorter braking distance. Because the silicon-containing formula is added to the tire and the shoulder is chamfered, the rolling resistance is reduced, and PS3 is more fuel-efficient than PP2.

New york Halo spa

　　　 Since salt is used as a spa, why should I come here and go directly to the seaside? To tell you the truth, Ray thinks so, too. However, it is said that "this newly-opened Halo spa in new york can treat asthma and drive away the cold". I can’t help but make little Ray curious.

　　　 Located in Manhattan, Halo Spa is the first of its kind in the United States, and it acts like a salt cave in Eastern Europe (like Slovakia).

　　　 Ray told me, "Halo spa also has a children’s room. The children’s room looks like a fairyland, which is very suitable for bringing children." Salt is imported from Ukraine, and it is on the walls and floors, and there are fine salt particles in the air, just like salt spray.

　　　 "I can even smell a smell of salt when I bring my daughter," Ray has always been a man with strong action and keen to reveal secrets. "Maybe I’m afraid that children can’t stay, and there are many toys, rocking wooden horses and TVs in it."

　　　 It is said that this therapy is very popular in Israel. Moreover, it is said that salt therapy can also treat skin diseases, heart diseases, vascular diseases and relieve fatigue and depression, and it is also helpful to quit smoking. That said, I think it should be promoted vigorously in China, so that adults and children don’t have to worry about catching a cold in cold places.

London The Dorchester Spa

　　　 The renovated and reopened Dorchester spa is regarded as the best spa in Britain in 2010. The location is good. The environment in the Mayflower District is absolutely unparalleled in London. The Dorchester Hotel is also famous as the "best business hotel". It is said that each guest has three employees to serve it.

　　　 Gillian, a friend from London, described it as "I know this newly renovated spa is good, but I didn’t expect it to be so good". Unlike traditional spa rooms, which all have a front desk, Dorchester spa is led by a special person directly through a dark aisle to a rest area, with a platinum mirror screen behind it. The highlight of the design is the curtain made of 72,000 South African pearls designed by Linton. Luxury is naturally everywhere, such as sofas and beds inside. If you want to show off, the spa room can really be made into a brand museum. Care products are no exception. Body care products include Vaishaly,Carol Joy London (ask Londoners about the popularity of these two products) and Kerstin Florian (first appeared in the spa room in London).

　　　 Some details in the SPA are also very popular, such as the sound insulation effect of the nursing room is very good. This point was carefully considered when redecorating.

　　　 Dorchester Hotel is a favorite hotel of Hollywood stars, so maybe when you are resting in public space, you will be sitting next to a star who has been in the limelight recently. When Harry Potter and The Lord of the Rings premiered in London, hotels were the first choice for holding receptions and staying with superstars. Sometimes you have to think, isn’t this luxury a bit too much?　

　　Beijing, December 10, 2007 (Reporter Han Meng) According to the News and Newspapers Summary of Voice of China, China Central Radio and Television Station, the Ministry of Industry and Information Technology recently introduced that China’s new energy vehicles have developed rapidly, and at the same time, they have integrated various revolutionary technologies such as artificial intelligence, Internet and big data, and the ecology of the automobile industry is being completely reshaped.

　　Yongding, Fujian, May 30 (Huang Qiuping Tang Yuzhou Li Changliu) As the Dragon Boat Festival approaches, villagers in Hongkeng Village, Hukeng Town, yongding county, Longyan City, Fujian Province are busy hanging mugwort leaves, kudzu vines and making zongzi.

　　Dragon Boat Festival is the annual "Zongzi Festival" and "May Festival" of the Hakkas, and it is one of the three major festivals of the Hakkas in a year. In the local Dragon Boat Festival, besides traditional customs such as making zongzi and dragon boat racing, there are also local folk customs.

　　Yongding county has a long history of Hakka culture. Hakka people generally call the Dragon Boat Festival "May Festival". Before sunrise on the day of the Dragon Boat Festival, almost every Hakka household sweeps the courtyard, and puts kudzu vine, calamus and mugwort leaves in the lintel and hangs them in the hall to avoid evil spirits.

　　"Our Hakka people’s custom of Dragon Boat Festival is to hang mugwort and kudzu vine, mainly to pray for peace and smoothness. mugwort and kudzu vine have the function of expelling poison and evil spirits, and more importantly, they have the function of expelling poison and avoiding plague, which is of medical and scientific value to our current traditional medicine." Lin Rigeng, a villager from Hongkeng Village, Hukeng Town, yongding county, said.

　　Hakkas also have the custom of wearing sachets during the Dragon Boat Festival, especially when children wear sachets to ward off evil spirits and plague. The sachets contain cinnabar, wormwood, etc., which are wrapped in red cloth and are fragrant. They are woven into ropes with colorful ropes and made into various shapes, forming a string, which is exquisite and eye-catching.

　　Lin Jia’s grandmother in Hongkeng Village, Hukeng Town insists on making sachets for her grandchildren and little grandchildren every year, so that they can wear them on the Dragon Boat Festival. According to Lin Apo, although there are many sachets on the market now, she feels that it is more thoughtful to make them by herself. She will sew the blessings into the sachets one by one, hoping to bring peace and happiness to the children. (End)

Cervical cancer is one of the most common gynecological malignant tumors in the world. In China, more than 100,000 people get sick and nearly 60,000 people die every year, which seriously affects women’s health and life safety. Considering the epidemic characteristics of HPV and the applicable population range of the vaccine, the World Health Organization (WHO) believes that the earlier the HPV vaccine is vaccinated, the greater the benefit, and recommends girls aged 9-14 as the main target population for HPV vaccination worldwide. In 2024, the Zhejiang provincial government will provide free domestic bivalent HPV vaccine for school-age girls in the province as a practical project for the people.

Vaccination principle: informed, voluntary and free vaccination.

Inoculation target: junior high school girls aged 13-14 in Wucheng district who have no contraindications to HPV vaccination and have not been vaccinated before.

Vaccination time: The vaccination clinic in Wucheng District is expected to carry out the first dose of free bivalent HPV vaccination service from May 25, 2024, and the second dose is expected to be carried out from November to December. Consult the vaccination clinics in detail.

Vaccination procedure: 2 doses were inoculated in the whole process (the interval between 2 doses was not less than 5 months).

Warm reminder: the number of places is limited, while stocks last. Girls aged 13-14 who have completed the preliminary survey and agreed to be vaccinated are invited to go to the vaccination clinic in the school territory accompanied by their parents.

Question 1: Why do you want to get HPV vaccine?

A: HPV is the abbreviation of human papillomavirus. At present, there are more than 200 types found. HPV can be divided into high-risk type and low-risk type. Studies have shown that about 99.8% of cervical cancer is caused by persistent infection of high-risk HPV. At present, there are 12 kinds of high-risk HPV, including HPV16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58 and 59. In addition to causing cervical cancer, high-risk HPV is also related to the occurrence of cancer in anus, head and neck, genitals and other parts.

The types that bivalent HPV vaccine can prevent are HPV16 and HPV 18. Vaccination with HPV vaccine can significantly reduce the incidence of persistent HPV infection, precancerous lesions and cervical cancer, which is the most economical and effective means to prevent cervical cancer. Relevant clinical trials and post-marketing effect evaluation data show that the HPV vaccines currently approved for marketing have good safety and effectiveness.

Question 2: Why is the age range of free vaccination defined as 13-14-year-old girls?

A: The World Health Organization (WHO) recommends girls aged 9-14 as the main target population for HPV vaccination. Vaccination of HPV vaccine for young girls can induce a higher level of immune response and have a better preventive effect. Studies have shown that there are two peaks of HPV infection among Chinese women according to their age, one is 17-24 years old and the other is 40-44 years old. Taking girls aged 13-14 as the key target group for HPV vaccination, giving priority to ensuring and greatly improving the HPV vaccination rate of adolescent women can make better use of effective social resources and achieve the best effect of the primary prevention strategy for cervical cancer.

Question 3: Can I get HPV vaccine during the physiological period?

A: If there are no special circumstances such as fever, anemia, infection or severe menstrual discomfort, HPV vaccine can be vaccinated during the physiological period.

Question 4: What should I pay attention to after vaccination?

A: After inoculation, you should stay in the inoculation unit for 30 minutes, and you can leave only after there is no abnormality. After inoculation, you should rest more and drink more water to avoid strenuous exercise. Due to individual differences, a few people may have transient adverse reactions such as local pain, redness, induration, fever and fatigue after vaccination, which generally do not need special treatment and can be relieved by themselves. When necessary, you can go to a regular hospital in time.

Parents and friends, the healthy growth of children is related to the future of the motherland and the nation, and it is also the greatest wish and expectation of every family. Protecting children’s health is the common responsibility of schools, families and society. Let’s join hands to do a good job in HPV vaccination, escort the healthy growth of children and give them a healthy and bright future.

Originally, as early as 2023, nanqiao town promoted group-based renovation work in rural areas with demand and conditions within the town, and effectively improved the living quality of rural villagers. The 15 households on the west side of the Five-Star Eight Group in Jianghai Village were the first group repair projects in the town, which were first completed in June 2024. Now, 15 villagers have been renovated and moved in one after another, expecting to move into a brand-new home before the Spring Festival, and the whole family will have a reunion dinner and enjoy a comfortable and comfortable modern pastoral life.

On the afternoon of the New Year, the warm sunshine fell on the homestead of five-star eight groups in Jianghai Village. White exterior walls, black tiles, supplemented by blue bricks and log elements, a row of newly renovated residential foundations with unified design is quite eye-catching in the village, and it also forms a strong contrast with a row of old residential foundations on the east side of the road. If you look closer, you can also find that there is a large parking area in the north of each house base, and the relatively independent courtyard of each family is divided by low walls and hedges in the south. In front of the courtyard, a flat waterfront trail and a hydrophilic platform were newly added. At this time, the old people who have already stayed in the "new house" are basking in the sun, waiting for the night to fall, and their descendants will return to the homestead to have a reunion dinner.

When it comes to the new look of the homestead, the villagers are all smiles. Because of this renovation, their living environment has been significantly improved, and even the younger generation is willing to go back to the old homestead for dinner every day. After 1995, Hong Jiaxuan simply regarded the old homestead as her new wedding house. She told reporters, "In the past, there was no air conditioning and natural gas in the countryside. It was cold in winter and hot in summer, and then cooking could only burn the stove. Now I have it all. My parents and I live directly in the countryside. The family lives quite comfortably and feels happier than living in a commercial house. "

As early as last September, He Shuizhang showed his new house to reporters. In the spacious living room of the new house, the furniture and TV cabinets were fully arranged, and the small yard in the south was also well-made by Lao He, which was quite warm. "It’s different from the previous days, and it feels better than the commercial housing in the town!" Csi said with a smile.

Living next door to He Shuizhang is his younger brother He Shuilong, who also moved in early in the second half of last year. According to Lao He’s recollection, most of the houses in the Red Star Group 8 were built in the 1970s, among which the two brothers are the oldest, with 45 years of mud walls and dilapidated houses. "Our houses are more than 40 years old. The house I built at the age of 21 is now 68 years old. Now it is much cleaner than before and we live more comfortably."

Hong Yuehua, who hasn’t moved into a new house, will come here for a walk every day to talk with his neighbors about his family, and his feelings of looking forward to staying are beyond words. "We used to be mud walls and mud boards. When we touched our hands, the mud would fall off. Everyone wanted to rebuild it. It happened that there was this project in the village, so we were all very satisfied!" Hong Yuehua said with emotion: "Now the sanitation has improved, the living conditions have improved, and the younger generation is willing to go back to the countryside. My grandchildren want to live in the countryside, saying that the air in the countryside is good, the sun is abundant, and the houses are well built. They all want to have a reunion year in the new house."

According to Gu Chunfeng, secretary of the Party branch of Jianghai Village, Wuxing Eight Groups, located on the south side of Nanting Highway and the east side of Shagang, are old houses built in the village for a long time. Over the years, many villagers have reported problems such as dilapidated houses, settlement and cracking, and they have a high voice for house repair. However, considering that Wuxing Eight Groups are the residential bases built in a row, there is no corresponding repair policy and opportunity. Just the year before last, Fengxian District issued a policy of repairing related groups, and the opportunity came. After several design demonstrations and summarizing villagers’ opinions, nanqiao town started the group repair work of 15 villagers.

"Our main purpose is to completely solve the problem of improving the living quality of houses that the people most expect through this group repair, and at the same time, it will also help the style of rural houses. Moreover, the biggest environmental sanitation difficulty in the village is the dilapidated foundation of houses. Renovation is also a cure." Gu Chunfeng said that after the renovation, nine families have moved in, three families are being renovated, and the rest plan to move in this year. The living quality of ordinary people has improved, and the style of rural houses has become better. It has also played a leading and exemplary role in the village. Next, the renovation project of more than a dozen households on the east side of the road is already in progress.

In fact, at present, there are two mature groups in the town of nanqiao town, namely, five-star eight groups in Jianghai Village and three groups in Guangming Village, and a total of 49 villagers are promoting the renovation work. According to Tao Longwang, deputy director of nanqiao town Urban Construction Center, the houses in nanqiao town are basically houses built in the 1970s and 1980s, and the houses have reached a certain age. However, due to the restrictions of previous planning and control and the current housing policy, it is more difficult for villagers to rebuild the houses sporadically. "If we concentrate on renovation, on the one hand, we can fight for the rights and interests of the people, and the price can be relatively cheaper. On the other hand, because it is a group renovation, we can also organize the houses as a whole. He said that next, when all the conditions are ripe, nanqiao town will continue to promote the group renovation work, effectively improve the living quality of rural villagers, enhance the level of rural revitalization, and create a new style of water town in the south of the Yangtze River that is "homesick and visible to development".

Original yang yang yang yang yang doctor from the album.

Author | Yang Yang (doctor of reproductive andrology, doctor of medicine, doctor of philosophy)

Hello, everyone. Some time ago, there was a heated discussion on Weibo.

There is a young woman in Shenzhen who goes out for dinner with a male friend. As a result, when she went to the toilet halfway, the man added some white powder with unknown composition to her cup.

Fortunately, the clerk of the restaurant stepped forward in time and told the woman to save her from disaster.

Then it got into Weibo, and even exploded three hot searches, and public opinion was in an uproar. The Futian District People’s Procuratorate also intervened in the investigation and issued relevant official notices:

At first, Dr. Yang thought it was an old scene of drug rape by acquaintances (because 80% of rape cases occurred between acquaintances).

But I don’t know if I don’t see it, but I die when I smile. Because this man is trying to rape women with this kind of thing.

Of course, in fact, the notice of Futian District Procuratorate is also flawed, because they got the name of this medicine wrong.

It’s not called tadalafil, but tadalafil.

(But not this kind of Lafite …)

In fact, it is a kind of viagra drug.

Of course, it is undeniable that this man is really bad, but fortunately, he is still stupid.

Therefore, although he has a thief’s heart and courage, but also put it into action, but even if he really succeeded, let the woman drink the water containing tadalafil, it will not cause any adverse effects on this woman.

Then let’s analyze, why do you say this man is an idiot?

There is a great probability because he has a big misunderstanding about this drug.

01

In fact, there have been a lot of misunderstandings about viagra drugs.

So that every time Dr. Yang prescribes this kind of medicine for patients, it is inevitable to explain its mechanism of action in detail, and then patients will agree to try it with a grain of salt.

Brother, it’s just a medicine, as for it.

Others simply refuse and insist on taking Chinese medicine to recuperate. ……

In fact, only this kind of drug is the first choice for treating ED, which has been officially certified by international guidelines for diagnosis and treatment.

Its scientific name is actually called "type 5 phosphodiesterase inhibitor" (a string of Chinese characters that everyone knows but don’t know what it means when combined).

English abbreviation is "PDE5-i"

The original intention of this drug was to lower blood pressure. As a result, in the clinical trial stage, it was found that the effect of lowering blood pressure was not good, but the patients who took the drug were unwilling to return the leftover medicine.

After careful questioning, I found that this medicine actually had the unexpected joy of improving erectile function.

And its mechanism of action is actually very simple. You can think of it as a muscle relaxant, that is, a valve switch.

However, the muscle it relaxes at a fixed point is the cavernous smooth muscle wrapped outside the cavernous artery of the penis.

This circle of muscles is tense, the artery is flat, the blood does not flow in, and Tintin is weak.

This muscle is flabby, the artery is full, blood flows in, and Tintin stands up.

It’s that simple.

02

But it is such a simple medicine that has caused all kinds of rumors that have been overwhelming for a long time.

The following are some common misconceptions about PDE5-i drugs:

one

"PDE5-i" equals an aphrodisiac.

This rumor has been around for years, but it is widely circulated.

I guess the boy who drugged Shenzhen is also out of a similar idea. It seems that a woman who eats this will have sex with someone.

This is understandable, because the "aphrodisiac" that can improve sexual function in our traditional little Huang Wenli can not only improve hardness, but also improve sexual desire.

But unfortunately, even if you give a man this kind of medicine, he won’t have any idea of rising desire, because this medicine has nothing to do with desire at all.

A valve switch, which doesn’t involve your brain at all, can improve your sexual desire?

2

After eating, it will always be hard.

In fact, taking Viagra can only help you restore normal erectile function, and there is a premise.

That is: you must have effective sexual stimulation and arousal to work.

It doesn’t mean that after you eat it, like a salted fish, Tintin will stand up by himself.

If there is no stimulation, people are fine, why should they get up and work?

Have you considered Tintin’s feelings?

And tadalafil is effective for 36 hours. If you eat one, you have to be hard for two days. Isn’t Tintin already ischemic and necrotic?

Is it necessary to cut off a tintin every time you eat a viagra?

three

"PDE5-i" will "hurt the body"

It is undeniable that some people may have some side effects after taking such drugs.

Common ones include blushing and rapid heartbeat.

Some people will have some back or muscle aches, and a few people will have a temporary blue eye.

But other than that, no adverse reactions have been found at present, and it will not "hurt the body."

It’s just a muscle relaxant. What kind of body did it hurt, dear?

03

Then again, what will happen if that stupid bad man in Shenzhen really succeeds in drugging?

That is to say: what will happen if a woman eats tadalafil?

At present, some studies have found that giving tadalafil to middle-aged and elderly women may help to improve their various female sexual dysfunction due to menopause.

Including sexual arousal difficulties, low sexual satisfaction and so on.

　　Core reading

　　The people of China, under the leadership of the Communist Party of China (CPC), have spent decades completing the industrialization process that developed countries have gone through for hundreds of years, creating a development miracle that attracts worldwide attention. The successful practice of Chinese-style modernization shows that the western modernization road is not the only way for mankind to modernize. The Chinese-style modernization road expands the way for developing countries to modernize and provides new choices for countries and nations in the world who want to accelerate their development and maintain their independence.

　　The establishment of the Communist Party of China (CPC) in 1921 was an epoch-making event. In the 100 years since the founding of the Communist Party of China (CPC), the people of China have been united and led to make remarkable achievements in promoting China’s socialist modernization through arduous exploration and continuous struggle. Today, our Party has led the people of China to embark on a new journey of building a socialist modern country in an all-round way.

　　The Communist Party of China (CPC) started China’s modernization journey at the time of national crisis.

　　China is an ancient civilization with a long history and splendid culture. It has been at the forefront of the world for a long time in history, and the hardworking, brave and intelligent people of China have made outstanding contributions to the progress of human civilization. After modern times, due to various reasons, China was trapped in poverty and weakness, and the Chinese nation was facing the crisis of national subjugation and extinction, which also made the people of China clearly aware of the backward situation in China, and thus began to seek reform, self-improvement and modernization.

　　In that era of aggression by western powers, incessant wars, social unrest and people’s displacement, in order to save the nation from peril and realize national rejuvenation, the people of China and countless people with lofty ideals made arduous explorations and epic struggles. Before the Revolution of 1911, the Taiping Heavenly Kingdom Movement, the Westernization Movement, the Reform Movement of 1898, the Boxer Rebellion and the New Deal in the late Qing Dynasty failed. Although the Revolution of 1911 ended the autocratic monarchy that ruled China for thousands of years, it failed to change the semi-colonial and semi-feudal social nature of China and the tragic fate of the people of China. After the Revolution of 1911, China tried various forms such as constitutional monarchy, parliamentary system, multi-party system and presidential system, and various political forces and their representatives appeared in succession, but failed to find the correct answer. The people of China still lived in misery and humiliation. Facts have proved that the self-improvement movement that does not touch the old social foundation, reformism in various names, the old peasant war, the democratic revolution led by the bourgeois revolutionaries, and various schemes that copy the western political system model can not complete the historical tasks of the Chinese nation to save the nation from extinction and resist imperialism and feudalism, nor can they stabilize the political situation and society in China, nor can they provide institutional guarantee for China to achieve national prosperity and people’s happiness.

　　During the period of poverty and weakness in China, various ideologies and thoughts were tried, but the capitalist road failed, and other "ideologies" failed to solve the future and destiny of China, let alone provide scientific theoretical guidance for China’s modernization. The October Revolution brought Marxism–Leninism to China and pointed out the direction for the rejuvenation of the Chinese nation and the modernization of China.

　　The Communist Party of China (CPC) stepped onto the historical stage at a critical moment when the Chinese nation was facing life and death. Since its establishment, the Communist Party of China (CPC) has been guided by Marxist scientific theory, taking communism as the highest ideal and ultimate goal, taking the happiness of the people of China and the rejuvenation of the Chinese nation as the initial heart and mission, and unswervingly striving for "China that pursues my ideal", leading the people of China to advance wave after wave and shed blood and sacrifice for national independence, people’s liberation, national prosperity and people’s happiness. Finally, the three mountains of imperialism, feudalism and bureaucratic capitalism were overthrown, and a new China was established, where the people were the masters of the country, which fundamentally changed the future and destiny of the people of China and the Chinese nation, irreversibly ended the tragic fate of China’s domestic troubles and foreign invasion after modern times, and started the great journey of China’s modernization.

　　Chinese modernization was formed in the process of continuous exploration by the Communist Party of China (CPC) people.

　　Different countries will choose different modernization paths because of their different historical culture, basic national conditions and historical missions. After the founding of New China, the Communist Party of China (CPC) led the people of China to continuously explore the road of Chinese modernization, made great achievements that attracted worldwide attention, created the miracle of rapid economic development and long-term social stability, and expanded the ways for developing countries to modernize.

　　Before the founding of New China, at the Second Plenary Session of the Seventh Central Committee of the Communist Party of China, Comrade Mao Zedong proposed to the whole party the historical task of "steadily transforming China from an agricultural country into an industrial country and building China into a great socialist country". Since the founding of New China, our Party has made arduous explorations in socialist modernization. Comrade Mao Zedong pointed out that our task "is to settle down so that we can build our country’s modern industry, modern agriculture, modern science and culture and modern national defense".

　　After the Third Plenary Session of the 11th CPC Central Committee, China’s socialist modernization entered a new historical period. Comrade Deng Xiaoping emphasized that whether modernization can be realized "determines the destiny of our country and nation" and "the modernization we are engaged in is Chinese-style modernization. The socialism we are building is socialism with China characteristics ". Under the leadership of the Communist Party of China (CPC), we have successfully embarked on the road of Chinese modernization. Based on China and facing the world, this modernization road insists on taking Marxism as the guidance, the Communist Party of China (CPC) as the highest political leading force, Socialism with Chinese characteristics road and people-centered, striving to build a prosperous, strong, democratic, civilized, harmonious and beautiful socialist modernization power, realize the great rejuvenation of the Chinese nation, strive to achieve common prosperity for all people, promote all-round development of people, and strive to promote world peace and development, which has distinctive characteristics of the times and China. This road to modernization not only conforms to the reality of China and embodies the laws of Socialism with Chinese characteristics’s construction, but also follows the trend of the times and embodies the laws of world modernization and the development of human society.

　　China’s modernization process is not smooth sailing, but under the strong leadership of the Communist Party of China (CPC) and the joint efforts of several generations of China people, China has gone from "lagging behind the times" to "catching up with the times" and then "leading the times", and the road of Chinese modernization has become wider and wider. China has moved from poverty to prosperity, becoming the second largest economy in the world, and its economic strength, scientific and technological strength and comprehensive national strength have greatly jumped; The people’s life in China has moved from insufficient food and clothing to a well-off society in an all-round way, and the happiness index has been continuously improved; China has developed from a traditional agricultural country to an industrial country, and its degree of industrialization is getting higher and higher, making it the largest manufacturing country; China has moved from closed and semi-closed to all-round opening, deeply participated in economic globalization and made more and more contributions to human civilization; China is getting closer to the center of the world stage, and its international influence has increased significantly.

　　The people of China, under the leadership of the Communist Party of China (CPC), have spent decades completing the industrialization process that developed countries have gone through for hundreds of years, creating a development miracle that attracts worldwide attention. The successful practice of Chinese-style modernization shows that the western modernization road is not the only way for mankind to modernize. The Chinese-style modernization road expands the way for developing countries to modernize and provides new choices for countries and nations in the world who want to accelerate their development and maintain their independence.

　　To build a socialist modern country in an all-round way, we must uphold and strengthen the overall leadership of the party.

　　The 19th National Congress of the Communist Party of China made a strategic arrangement to advance the goal of the second century in two stages, that is, to basically realize socialist modernization by 2035 and to build China into a strong, prosperous, democratic, civilized, harmonious and beautiful socialist modernization country by the middle of this century. Based on the reality of the new development stage, the Fifth Plenary Session of the 19th CPC Central Committee put forward the long-term goal of basically realizing socialist modernization by 2035. To build a socialist modern country in an all-round way, we must uphold and strengthen the overall leadership of the party.

　　The modernization to be realized in China is the modernization with a huge population, the common prosperity of all the people, the coordination of material civilization and spiritual civilization, the harmonious coexistence of man and nature and the modernization of peaceful development. Realizing such modernization is the common aspiration of all Chinese people, and it is also the ideal and pursuit, responsibility and responsibility of the Communist Party of China (CPC) people. To realize such modernization, we must have a "backbone" and a strong leadership core. In contemporary China, this core can only be the Communist Party of China (CPC) as the highest political leading force. General Secretary of the Supreme Leader stressed: "History has proved and will continue to prove that without the Communist Party of China (CPC)’s leadership, national rejuvenation must be a pipe dream." Therefore, to build a socialist modern country in an all-round way, we must uphold and strengthen the overall leadership of the Party, strengthen the "four consciousnesses", strengthen the "four self-confidences" and achieve the "two maintenance".

　　To uphold and strengthen the overall leadership of the party, we must comprehensively promote the new great project of party building. At present and in the future, China’s development is still in an important period of strategic opportunities, but there are new developments and changes in both opportunities and challenges, and the domestic and international environment facing China is undergoing extensive and profound changes. Although China has unique political advantages, institutional advantages, development advantages and opportunity advantages, and there are many favorable conditions for building a socialist modern country in an all-round way, the problem of insufficient development imbalance is still outstanding, the historical task to be completed in promoting modernization is still very arduous, and the contradictions, difficulties and risks faced in reform, development and stability are still very complicated, which puts new demands on the party’s ruling ability and leadership level. At present, party building is still facing a series of new situations, new problems and new challenges. It is more arduous and urgent than ever to implement the task of managing the party in an all-round way. To ensure that the Party is always in the forefront of the times in the historical process of profound changes in the world situation, always the backbone of the people of the whole country in the historical process of coping with various risks and tests at home and abroad, and always the core of strong leadership in the historical process of upholding and developing Socialism with Chinese characteristics, we must strengthen Party building with the spirit of self-revolution, and constantly enhance the Party’s ability of self-purification, self-improvement, self-innovation and self-improvement.

　　On the occasion of celebrating the centenary of the founding of the Communist Party of China (CPC), we need to take into account the overall situation of the great rejuvenation strategy of the Chinese nation and the unprecedented changes in the world in the past century, conscientiously sum up the Communist Party of China (CPC)’s valuable experience in leading Chinese modernization, raise it to a theoretical height, and constantly enrich the treasure house of Marxist modernization theory; Unswervingly promote modernization, promote the great rejuvenation of the Chinese nation with Chinese modernization, constantly make new and greater contributions to mankind, and fully demonstrate the characteristics and advantages of Chinese modernization. Standing at the key node of the historical intersection of the goals of "two hundred years", we should constantly improve our political judgment, political understanding and political execution, and constantly improve our political ability, strategic vision and professional level to grasp the new development stage, implement the new development concept and build a new development pattern, so as to ensure that socialist modernization will be basically realized by 2035 and China will be built into a strong, prosperous, democratic, civilized, harmonious and beautiful socialist modernization country by the middle of this century.
