摘要
从能量守恒的角度论述了离子速度成像技术的基本原理,从"离子透镜"、二维探测、数据处理的原理与方法等方面介绍了离子速度成像技术.将离子速度成像技术与"完全非弹性碰撞"问题及夫兰克-赫兹实验等内容相结合,为学生直观地学习和掌握微观世界的"碰撞"问题及微观世界的能量守恒定律提供了一种实验方法.
The technology of velocity-map imaging is introduced into the physics experiment teaching, the basic principle of velocity-map imaging technology is expounded using energy conversation law. The technology of velocity-map imaging is presented from three aspects： the principle of ion lens, the technology of two-dimensional detection, and the method of data analysis. The whole presentation is combined with the completely non-elastic collision and experiment of Frank-Hertz, etc. , which is more intuitive for students to study and master collision phenomenon and energy conservation.
