摘要
分析了光电效应实验中测试普朗克常量传统的数据处理方法的局限性 ,提出了运用非线性最小平方拟合的方法进行曲线拟合并用曲率法确定遏止电压 Us,经线性拟合后可获得较精确的普朗克常量 .
The limitations of traditional data-processing method in the experiment of testing Planck constant in photoelectric effect are analyzed. Applying nonlinear smallest-square fitting and curvature method, the stopping voltage is determined. The precise experimental result is obtained after linear fitting.
