光电效应实验及理论解释,为量子理论的建立奠定了基础,在光电效应伏安特性实验中,如何有效减少实验影响因素,提高测量结果的精确度,成为光电效应伏安特性实验改进的一个关键点。本从光电效应实验测量的伏安曲线出发,分析理论与实验结果上的差异,提出了影响实验结果的因素以及相应的实验操作办法,为光电效应伏安特性实验的改进,获得更加精确的实验数据以及光电效应实验的应用奠定了基础。

The experimental and theoretical explanation of the photoelectric effect is the basis of the establish-ment of the quantum theory. In the experiment of the photoelectric effect,how to reduce the influence factor and improve the accuracy of the measurement results is a key point for the improvement of the volt-ampere characteristic experiment of the photoelectric effect. In this work,the differences between the theoretical and experimental results were discussed,and the factors which influence the experimental results and corresponding experimental solutions were given. This laid the foundation for the more accurate experimental data,further im-provement and application of the photoelectric effect experiment.
