摘　　要：关于夫兰克-赫兹实验,学生在原子吸收能量的量子化特性及反向拒斥电压的理解上存在难点。针对这一情况,通过设计三种不同的实验条件将难点进行分解,根据实验结果提出了三步法讲解夫兰克-赫兹实验原理的方案,为实验教学提供一定参考。There are certain difficulties for students to understand the quantum properties of atomic energy ab-sorption and the exclude voltage in Frank-Hertz experiment.In order to resolve the problems, three different ex-perimental conditions are designed to decompose the difficulties.A teaching Scheme with three steps to explain the principle of Frank-Hertz experiment is proposed through the experiment results to put forward some reference for teaching thoughts and method.
