利用光电效应测定普朗克常数,是高等院校理工科学生做的一项实验。关于这方面已有不少文章作了介绍。尽管所介绍的实验中最终均得出了接近理论的普朗克常数值。但为了使实验更加完善和加深理解,我们认为还需对测定方法和管子特性的影响等问题做进一步讨论。

The use of photoelectric effect measurement Planck constant, science and engineering students at colleges and universities to do an experiment. There have been many articles on this topic. Although all of the experiments introduced in the present study resulted in near-theoretical Planck’s constant values. However, in order to make the experiment more perfect and deepen the understanding, we think that the methods of determination and the influence of the characteristics of the pipe need to be further discussed.
