贵刊在89年12期中刊登了关于“超球”碰撞实验的文章.“超球”碰撞这个实验确实新颖有趣,因而不少物理刊物曾介绍过。如果将该实验作为“弹性碰撞”这节课的补充演示,必将强烈地激发学生学习兴趣。但是,迄今为止还未见有文章介绍过好的实验方法,如果按该文章介绍的方法实验,实际上是很难获得 You published an article on the “hypersphere” collision experiment in the 12th issue of the year 89. “Hypersphere” Collision This experiment is really new and interesting, so many physical journals have introduced it. If this experiment is used as a supplementary demonstration of the “elastic collision,” this will surely stimulate students’ interest in learning. However, so far there have been no articles that have introduced good experimental methods. It is actually very difficult to obtain the experimental methods described in this article.
