Drilling the floor, drilling sleeping bags, sleeping in military beds, a few stools, and even sleeping directly on the conference table ... There are a variety of accommodation methods, just because there are scientific tests that they can't rest assured, the delayed model tasks, you can't stop, you can't stop. Clinical trials below.

In mid -March this year, seeing the epidemic increasingly serious, a number of researchers from the Shanghai Branch of the Chinese Academy of Sciences lived in the office.

This residence is June 1st. The persistence of more than 80 days in exchange for a number of scientific research results. Life presses the pause key, but scientific research has been charging. No conditions? Then create conditions to charge!

Send a satellite to Jiuquan

How long does it take to transport a satellite from a highway to Jiuquan?

During the epidemic sealing and control, a small unit from the Institute of Micro Satellite Innovation of the Chinese Academy of Sciences answered this question:

74 hours!

Generally, satellites are transported through special planes. Affected by the epidemic, new technical test satellites have to be transported through the highway. Because a safety inspection must be performed every 5 hours, this way go and stop. From 7:00 on May 7 to 9:00 on May 10th, after 17 inspections, the satellite successfully spanned 3,000 kilometers and arrived at Jiuquan satellite satellite satellite. Launch center.

The new technical test satellite is a satellite with the characteristics of the Chinese Academy of Sciences. Its goal is to explore pure new technology. It is equipped with 15 new loads including 46.5 nanometer ultraviolet solar imagingers, lobster -eye X -ray telescope, high -energy explorer, parasitic infrared perception camera, etc., and will also perform spatial micro -vibration suppression, expansion radiator and other satellite platform universal technology. Verification lays the foundation for future space detection and remote sensing applications.

"Innovation and innovation to innovate is the responsibility given to us by the party and the country." Zhang Xiaofeng, the secretary of the Second Party Branch of the New Technology Test Satellite and Secretary of the Second Party Branch of the Institute of Science Satellite, told the Journal of Science.

In order to successfully leave the factory at the end of March, Zhang Xiaofeng has lived in the unit from March 14. On March 27, he returned home. Unexpectedly, he suddenly received a notice from the city's closed control that night. Pudong will take the lead in sealing the next morning.

"At that time, he was very anxious and rushed to the unit. Director Zhang Yonghe was there. We immediately called and shouted the backbone of scientific research. Everyone was calling." Zhang Xiaofeng recalled.

That night, the left -behind team of 15 people gathered. Later, the left -behind team was responsible for the debugging of the on -site instrument, and other home staff conducted remote data reading.

Because there are only 4 beds in the unit dormitory, most people can only sleep in the office. This also allowed them to form the habit of working in the laboratory during the day and the office in the office at night, and often discussed at 12 o'clock in the middle of the night.

However, in Zhang Xiaofeng's view, colleagues in the office of home office are harder, "working online, take care of children, and snap -up materials, often feathery." He also helped the home at 6 am, and tried only once a few days.

After the satellites leave the factory, how to send people and satellites to Jiuquan has become a big problem. In the end, the Institute decided to take a bus. Considering the impact of the epidemic, 17 test team members ate and live in the car all the way, and even prepared urine. After bumping for more than 40 hours, they finally arrived at Jiuquan.

At present, more than 30 players of the Teacher's Teacher's Timber Satellite Innovation Research Institute came to Jiuquan in three batches in three batches. Many of them had to work here to work successfully. For so long from home, Zhang Xiaofeng said: "The most than grateful is the family."

Zhang Xiaofeng was born in 1980. Most of the scientific research backbones of the team are "post -85s" and "post -90s". For example, the "post -85s" Huang Jiangjiang and He Junwang were able to return to the unit on the night of March 27; "post -90s" Liu Yan remotely guided the on -site personnel to confirm relevant assembly during the home, and also guaranteed other model tasks. Remote tests; "post -90s" female astronauts Bi Xingzi and Li Tiantong were unable to come to the scene because the load unit could not come to the scene, and she took a lot of extra work.

"To be honest, I admire them. After sitting for 46 hours, I feel shaking, but these two girls have no complaints." Zhang Xiaofeng said, "I now realize that young people can't eat hard, they can't eat hard, This is completely misunderstanding. The young people here are full of energy, responsibility, dare to assault, and have the spirit of manned space -manned spirit that is "particularly able to endure hardships, fights, specially capable, and dedicated."

Clinical trial

On June 1, Shanghai "restarted", but Zhang Manzhou, a researcher at the Shanghai High Research Institute of the Chinese Academy of Sciences, could not go home. It wasn't until June 3 that he was relieved. On this day, he and the team completed all the clinical trials of 47 subjects in the first registered unit of the first domestic proton therapy device in my country. At this time, Zhang Manzhou has adhered to the Tumor Proton Center of Ruijin Hospital for 84 days.

Proton therapy is one of the most advanced radiotherapy technologies in the world. Its advantage is that after the proton beam enters the body, it will form a dose peak, that is, the Prague peak, which can "accurate blasting" the tumor. However, this technology is currently only mastered in developed countries such as Europe, America, and Japan. The introduction of technology means that patients must withstand high treatment costs.

In 2012, the Shanghai Academy of Sciences, Shanghai Academy of Sciences, and major projects of high -tech industry development, the first domestic proton treatment demonstration device jointly undertaken by the Shanghai Academy of Applied Physics, the Shanghai High Research Institute, Ruijin Hospital and other units, and other units. Construction of officially establishing projects. According to Zhang Manzhou, the rotor frame weighs 180 tons of proton treatment devices, but the accuracy must be controlled at less than 1 mm during treatment. It is a veritable large -scale precision medical device. The technology is very complicated.

Ten years of research, the dawn is imminent, however, the sudden epidemic disrupted the rhythm of work.

After Jiading's control on March 12, there were only four staff members at the least at the time. They had to perform clinical treatment and rotating machine acceptance at the same time. Each person worked for more than 18 hours per day. According to clinical trial requirements, the normal treatment of patients cannot be interrupted for more than two days, otherwise the clinical trials that have been abandoned before the clinical trials starting in November 2021.

"We thought of it at that time to support it anyway." Zhang Manzhou told the Journal of China.

After the city's closed control in April, the team gathered in the 10 -person team stationed in Ruijin Hospital to share various tasks.

Unexpectedly, the accident occurred -a clinical trial bed was faulty and could not be used. What is even more crashing is that when the team contacted South Korean suppliers overnight, it was learned that the opponent's team had been dissolved. Clinical trials are facing the risk of failure again, and everyone has no sleep overnight.

The supplier can't repair it, you can only rely on yourself. The team member judged that the failure was a software problem, so he started to study the relevant code. Until the afternoon, they realized that the problem might come from the hardware and immediately asked for help from other teams in Shanghai Light Source. Fortunately, a PLC controller experts were connected to the video and found damage components in just two hours.

The team members were not happy, and the trouble came again -there was no spare parts in the spare parts. When Zhang Manzhou was about to ask colleagues who lived in Jiangsu to buy and then delivered it, the colleagues responsible for purchasing had inquired about the spare parts had been bought and just delivered it two days before the seal control. Several people at the scene looked around, and finally found a courier that had not had time to disassemble on a desk. Open it, it was this "life -saving" spare part.

At this time, it has passed 30 hours before the failure, and everyone's mood like a roller coaster finally landed smoothly.

Zhang Manzhou said that in addition to the faulty treatment bed was produced by foreign companies, other treatment beds have been localized.

Nowadays, the clinical trials of the two treatment rooms in the first registered unit have ended, and it is closer to the patient to get the registration certificate and open to the patient. "According to the international statement, a proton treatment device is required for every 10 million people, and there are nearly 20 units in Japan. We must continue to accelerate so that Chinese people use high -quality domestic devices early." Zhang Manzhou said.

Uttle the pressure with action

On March 23, Liu Yin, a researcher at the Shanghai Institute of Technology and Physics of the Chinese Academy of Sciences and the head of the Star Highlighting team, cleaned up a simple dress and put his family into the office. Several wooden chairs were his couch. At this time, it is more than a week before the city's city closed control.

Such a strong sense of anxiety originated from Liu Yin's long -term research on the research of aerospace loading. He led the team to undertake and host the research and development of dozens of national major projects infrared/high -spectrum camera. At the end of March, the team needed to complete the development of high -scoring 01A star high spectrum cameras, and delivered the overall satellite. Liu Yinnian knew that at this festival, he had to do a little bit.

High score 5 01A star is the "Sisters Star" launched in 2018. Due to the urgent demand of the country, the development cycle of the high score 5 01A star has been compressed from the conventional two or three years to 18 months, and the development cycle of the high spectrum camera has also been compressed by nearly half. For more than a year, the development team has strived to cine, and even the Spring Festival has not been rest.

"In the face of this unprecedented epidemic control, although everyone is waiting for it, it is inevitable that the pressure is under great pressure." Liu Yinnian told the China Science News that the team's development task has been saturated this year. In the test of the rail load, there are 5 major countries in major national projects that are about to be issued or in the process of argument ...

Fighting pressure, only rely on action. Sun Dexin, another technical leader of the team, also entered the office 1 week in advance; after the end of March, after Shanghai entered the static management of the whole region, 31 people in the team took the initiative to apply for a staying unit. Later, under the orderly arrangement of the institute, More than ten people return to post ...

Dozens of people live together, work together, check together ... In the evening, they lay down to discuss the problem, without the "sitting crisis" at the meeting, many thoughts and inspirations naturally emerged in the "lying talks".

Getting along the day and night also allowed everyone to have a new understanding of the "post -80s", "post -90s" and "post -00s" in the team: Liu Guoqing, who is newly upgraded to his father, will get a haircut, which has become a special barber in everyone; "Take the initiative to undertake the tasks of cleaning and delivery of meals, and even carefully clean up the dead corners of hygiene; in order to ensure that the work is uninterrupted, more than a dozen young people responsible for electronic testing are sleeping directly at the work site, not enough to go out of the building ...

Liu Yinnian said: "For more than two months, everyone has lived a collective life again, has more exchanges, and the relationship is deeper. Although the number of people in the early stage of sealing and control is not enough, everyone’s cohesion and combat effectiveness have been in a step, and they have rushed back and rushed back. Time. "According to reports, the high score 5 is the satellite with the highest spectral resolution in land observations in my country, and the spectral resolution of the high score 5 01A star high spectrum camera will be further improved. The frequency and more "clearly" observe water pollution, soil nutrients, vegetation diseases and insect pests, greenhouse gas dot sources and underground mineral resources ...
