摘　　要：利用PN结正向压降温度特性实验组合仪,通过测量PN结的正向伏安特性,在PN结电流小于200μA情况下,采用非线性回归方法计算了电子电荷量,该测量值1.582×10-19 C,与公认值1.602×10-19 C的相对误差仅为1.2%.The PN junction forward voltage characteristics were measured by using the temperature dependence on the positive-going voltage drop of PN junction. The electronic charge was ealeulated to be by nonlinear regression of electronic charge when the current of PN junction is less then 200 μA . The measured value of the elemental charge is 1. 582 × 10^-19 C. The relative error between the measured value and the recognized value of the elemental charge is 1.2%.
