摘　　要：针对夫兰克-赫兹实验中测量曲线易受各管极电压影响的问题,通过独立改变各管极电压的方法进行了数据测量,并分别就灯丝电压UF、第一栅极电压UG1K、拒斥电压UG2A对实验曲线的影响进行了分析讨论,得到了一些有价值的规律。此外,还对IA—UG2K曲线中出现的"台阶现象"、"双谷现象"进行合理的解释。In view of problem that the measured curves can be affected likely by voltage of tube-poles in Franck-Hertz experiment,experimental data are measured by varying voltage of tube-poles,respectively. The effects of filament voltage UF,fist grid voltage UG1 Kand repulsion voltage UG2 Ato experimental curves are analyzed and discussed relevantly and several valuable principles are induced. In addition,the ladder effect and two-valley effect appeared in IA-UG2 K curves are also explained reasonably.
