摘要
在夫兰克-赫兹实验中,对加速电压分别采用4种不同间隔进行数据测量,在Origin7.5中画图,并进行数据处理,得到4组第一激发电位值。当加速电压间隔1.5 V时,在不降低测量精度的情况下,减少了测量数据的个数,在学生测量数据过程中可以采用这种间隔进行数据记录。
In Franck-Hertz （H-F） experiment, data were measured by four different intervals of accelerated voltage. The data were plotted and processed by Origin7.5 and four results were obtained. The accuracy of the first excited voltage with 1.5 V interval of accelerated voltage is high and the number of data is less than that of 0.5 V interval. The 1.5 V interval may be applied when students measuring the data of F-H experiment
