1969年9月29日到10月3日在苏修召开了等离子体约束方式的讨论会。会上对1968年8月于苏修召开的第三次国际原子能会议上发表的“托卡马克”装置所取得的成绩作了报告,它为核聚变研究工作提供了新的线索;与此同时,美帝报告了用激光器进行等离子体测量的新方法,它给这条线索增添了方便。美帝报告了其最佳实验成果—— September 29, 1969 to October 3 in Su repair held a plasma restraint seminar. The achievements of the “Tokamak device” published at the Third International Atomic Energy Conference held in Suxiu in August 1968 were reported, which provided new clues for the research on nuclear fusion. At the same time, the US imperialists reported a new way to measure plasma with a laser, adding to the convenience of this clue. US imperialism reported its best experimental results -
