摘要
针对实验教学难点 ,充分利用实验室设备 ,设计了夫兰克 -赫兹实验演示系统 .通过课堂实验演示 ,学生可以了解参量变化对实验的影响 ,获得不同实验参量曲线 ,从中选择理想的实验参量供实验时设定 .
In order to overcome the difficulties in teaching and take full advantages of the experimental facilities, the Frank-Hertz demonstration system is developed. It helps students to obtain some knowledges about the effects of the parameters on the experiment, and to get different parameters curves, which can help students to select the best parameters in the experiment.
