摘　　要：设计了基于LabVIEW的光电效应数据处理系统,利用动态程序控制技术,实现多面板控制功能;引入数组控件,解决了输入数据量受限制的问题;系统能够实现对输入数据进行曲线拟合,并通过XY图显示输入数据的关系曲线图,最后计算出普朗克常量,并算出相对误差。该系统解决了数据计算量大、处理繁琐的问题,提高了实验效率。The data-processing system for Photoelectric Effect experiment is designed based on LabVIEW. Multi panel control function is realized by technology of VI server. The problem of the quantity of data is limited which is solved by array control. The function of curve fiting, displaying curve graph, calculating the Planck constant and the relative error are realized by the system. The problem of the complex calculation of data processing is solved. And the efficiency of the experiment is improved.
