塞曼效应实验可以测量电子荷质比,实验中发现测量值比公认值小30%～50%,通过查找原因最终发现说明书所提供的法布里-珀罗标准具两块镜片的间距不准确是导致误差的主要原因。为提高测量准确性,应当为塞曼效应实验配备测量磁场强度的特斯拉仪。

The charge-mass ratio of electron can be measured from Zeeman effect experiment.In the experiment performed by the students,the measured value is 30～50% less than the standard value,and through detailedly studying we finally find that the main reason accounting for this big error is that the distance between the two pieces of reflecting mirror installed within Fabry-Perot standard device,offered by the paraphrastic list,is not correct.Moreover,in order to improve the measuring accuracy of charge-mass ratio of electron,the Tesla meter,which is used to measure the intensity of magnetic field,should be equipped for Zeeman effect experiment.
