摘　　要：本文介绍了弗兰克一赫兹实验的CAI教学软件的制作和使用。生动形象地描述了原子内部能量的量子化情况及气体放电现象中低能电子和原子之间的相互作用。重点突出反映了加速电压与流经弗兰克一赫兹碰撞管的电流之间的夫系,能够有针对性的测量原子的第一激发电位。This paper presents the design and usage of a CAI teaching software on Franck-Hertz experiment.The software describes,in a figurative way,the energy quantization within atoms and the interactions between low-energy electrons and atoms in gas discharge.It emphasizes the relationship between the accelerating voltage and the current passing through Franck-Hertz collistion tube and allows the messurement destined to the first excited to the first excited potential of aloms.
