摘要： 为了研究氩原子的激发电位，对充氩弗兰克一赫兹管在不同的灯丝电压、栅极电压和加速电压下进行了实验，分析了获得的实验曲线；得到使用该弗兰克-赫兹管实验时的最佳参数为灯丝电压3．2V、栅极电压1．0V、拒斥电压10.0V,在该参数下测得氩原子的激发电位为11．61V，并进行了详细的讨论；表明该值本质上应为氩原子第一亚稳态的激发电位，或两个亚稳态激发电位的一定概率比．
关键词: 弗兰克-赫兹实验, 第一激发电位, 能量量子化效应, 亚稳态
Abstract: The Ar atomic excitated voltage are studied from the experiment in different parameter, and the experimental curve are analyzed; The optimum parameter are the filament voltage is 3.2 V, the grid voltage is 1.0 V and the spurn voltage is 10.0 V are brought forward to use the F-H experiment. The first excitated ex- plode voltage of Ar is 11.6 V. The result shows the value should be the first sub-tranquilization excitated voltage, or the two sub-tranquilization probability ratio.
Key words: F-H experiment, first excitated voltage, energy quantum effect, sub-tranquilization state
