4. China is the first country to realize horizontal well drilling for deep-sea combustible ice
2020 year 3 month 26 Japan , According to the Ministry of natural resources , The second round of trial production of natural gas hydrate in China's sea area is successful , And overfulfilled the target .
Natural gas hydrate is usually called combustible ice , In the depth of water 1225 The trial mining of Shenhu sea area in the South China Sea has created “ Total gas production 86.14 Thousands of cubic meters 、 Average daily gas production 2.87 Thousands of cubic meters ” Two new world records .
China has also become the first country in the world to adopt horizontal well drilling and production technology to test the production of natural gas hydrate in sea area .
5. Scientists found wheat “ cancer ” buster
Wheat scab , It is one of the most destructive and difficult fungal diseases in the world , There's wheat “ cancer ” Known as the . Kong lingrang's team of Shandong Agricultural University cloned the main gene of scab resistance for the first time from Thinopyrum elongatum Fhb7, It was successfully transferred to wheat varieties , It is the first time to confirm and verify that it not only has stable resistance to scab in wheat disease resistance breeding , And it has a broad spectrum of detoxification .
at present , existing 30 A number of units conducted extensive trials , The results were good . This achievement has found a way to solve the global problem of scab “ Gold key ”.
6. Scientists have achieved “ The advantages of quantum computing ” Milepost
The team of Chinese scientists has constructed 76 Prototypes of quantum computing with photons “ The nine chapter ”, It has realized the practical prospect of “ Gaussian boson sampling ” Fast task solving , It makes our country reach the first milestone of quantum computing research —— The advantages of quantum computing , It lays a technical foundation for the realization of large-scale quantum simulator which can solve the problems of great practical value .
7. Scientists recreate the earth 3 More than 100 million years of history of biodiversity change
The origin and evolution of life is one of the top ten scientific mysteries in the world .
Professor Fan junxuan, Nanjing University 、 Academician Shen Shuzhong and others built their own large database , Independent research and development of artificial intelligence algorithm , utilize “ Tianhe no.2 ” Supercomputing has made a breakthrough , To obtain the The world's first high-precision Paleozoic 3 The curve of marine biodiversity over the past billion years , Its resolution is higher than that of similar international studies 400 times . The new curve accurately depicts many major biological extinctions and radiation events in geological history and their relationship with environmental changes .
8. China's highest parameter “ Artificial sun ” Built
New generation of controllable nuclear fusion research facility in China “ China circulator 2 M”（HL-2M）12 month 4 It was officially built in Chengdu on July , It marks that China has officially stepped into the forefront of global controllable nuclear fusion research ,HL-2M Will further accelerate the pace of human exploration of future energy .
This device is the largest one in China 、 Advanced Tokamak device with the highest parameters , It is a new generation of advanced experimental research device for magnetic confinement fusion in China , Can achieve high density 、 High specific pressure 、 High bootstrap current operation , It is an important supporting device for the great leap forward development of China's nuclear fusion energy development .
