Tsinghua High School students won the 2020 Haidian District Youth Science and Technology Innovation Competition
The project "Zangqi Jiuqi Machine Game Teaching and Playing Platform based on Deep reinforcement Learning and Self-play" integrated Monte Carlo tree search algorithm and deep reinforcement learning, designed the machine game algorithm of Zangqi Jiuqi, and designed and developed the online game teaching and playing platform of Zangqi Jiuqi。As an unpopular kind of chess, long chess currently lacks the corresponding playing platform, which can not realize man-machine playing。Since the action space of long chess is huge and the actions of both sides are transparent and zero-sum game, the classical machine game algorithm Monte Carlo tree search algorithm is used to solve the problem, and the reinforcement learning method is also used, and the model is played against itself to generate training data。
Water-borne pathogens are widely found in all kinds of water bodies, including pathogenic microorganisms that can infect human beings in various ways. When people are exposed to polluted water bodies at a certain concentration, they will be infected with a series of diseases, such as diarrhea, cholera, dysentery, typhoid fever and polio。A short period of peak concentrations of pathogenic microorganisms can significantly increase the risk of disease infection, potentially causing outbreaks of waterborne diseases。For these reasons, Jiang Qi believes that it is not only possible to rely on terminal detection to ensure the safety of drinking water in terms of microorganisms, but it is necessary to study and try to assemble portable detection devices for real-time and rapid monitoring of water sources。Therefore, Jiang Qi carried out the research on "Development of a portable device for quantitative detection of pathogens in Water Sources based on ring-mediated isothermal amplification technology"。
The topic of "Research on Promoting the construction of Beautiful Huaijiu River Basin at a high level" comes from the fact that Wang Shuyang once went to Huaijiu River Basin in the mountains to look for peach blossom jellyfish。Although there were no jellyfish after several twists and turns, they became interested in benthic animals。She found obvious differences in benthic organisms in different sections of Huaijiu River。After consulting literature and consulting experts, the analysis of the reason is that the water quality of the upper reaches of the river is better, the middle reaches are worse, and the downstream is slightly improved。After investigating the basin for four consecutive years, she submitted proposals to protect the ecological environment of the basin in 2019。At the end of the same year, the COVID-19 pandemic suspended the operation of folk tourism in the basin。This is an opportunity to capture blank data that will reflect the impact of tourism on benthos。Last June, she got the chance to survey the benthos in the basin。Combining the dual needs of ecological protection and ecological enrichment in the basin, she put forward suggestions for high-level development of local ecotourism from five aspects, including comprehensive remediation, ecological education and digital application。
More and more attention has been paid to the impact of haze on people's life and health。Smog is mainly formed by many small particles suspended in the air under specific climate conditions。Due to the wide range of haze sources, the particle size and types of haze particles are different. Do different sizes and types of haze have the same impact on human beings？This question led to the study of the topic "Toxic side effects of different types of haze particles and their plants.。First, Han Runkun's group collected haze particles from the new fan system and cultured them with macrophages, and found that haze particles could easily enter the cells;Next, two kinds of haze particles with different sizes were cultured together with cells, and it was found that the diameter was less than 2.The haze of 5 microns has more toxic and side effects on cells;In order to study the effects of haze types on cells, they synthesized calcium carbonate particles and purchased metallic copper powder and silicon carbide powder, all of which have diameters less than 2.At 5 microns, the three powders were cultured with cells, and it was found that copper powder had the greatest side effect on cells, and calcium carbonate particles had the least side effect。Through this study, they are more aware of the impact of haze on human life and health, and are determined to start from themselves, adhere to green travel, and reduce the generation of haze。
