The reporter recently learned from the 54th international chemical Olympic Organizing Committee that after nine days of fierce competition, all four players of the Chinese team won the gold medal and won the top three gold medals. From July 10 to 18 Beijing time, the 54th international chemical Olympics was held online at Tianjin Nankai University. 326 young players who love chemistry from 84 countries and regions gathered in the clouds and competed in the same field, resulting in 36 gold medals, 71 silver medals, 103 bronze medals and 23 honorary awards. The top three gold medal winners are Fu Zhou (China), Zhang XURUI (China) and he wen (China). Chinese players have been outstanding in this international competition. Since 1987, when China first formed a team to participate in the 19th International Chemical Olympics held in Hungary, China has sent 140 athletes so far, of which 107 won the gold medal, 29 won the silver medal and 4 won the bronze medal. The theoretical examination questions of this competition cover inorganic chemistry, organic chemistry, physical chemistry, structural chemistry, analytical chemistry, etc. The test questions show the outstanding contributions made by Chinese chemistry to the world's scientific and technological progress. In order to enable the contestants to experience the operation of chemical experiments in the "cloud", the Organizing Committee of this competition introduced virtual simulation experiments and online experiment questions for the first time. Through the use of computer simulation, virtual reality and other technologies, the close combination of theory and experiment was realized, so that the contestants could break through the time and space constraints and experience the fun of chemical experiments. The organizing committee also set up a "golden monkey Award" to reward young players who performed well in the experimental topics. The International Chemistry Olympics (IChO) is the world's largest and most influential chemistry competition for high school students, held annually. The first international chemical Olympics was held in Prague, the former capital of Czechoslovakia, in 1968. This competition is jointly sponsored by the China Association for science and technology and the Tianjin Municipal People's government, and jointly organized by Nankai University, the China Chemical Society, the youth science and technology center of the China Association for science and technology, and the Tianjin Association for science and technology. Around the competition slogan of "change, creation, and integration", it will promote science and technology to be good, promote openness and integration, encourage innovation and creation, and stimulate scientific interest.
