灵敏电流计内阻测量的数据处理方法

Data processing methods for measuring the internal resistance with sensitive current meter

灵敏电流计内阻的测量结果误差较大，本文通过对一组实验数据分别用逐差法和最小二乘法进行计算，并用误差分析来说明，选择合适的数据处理方法，有助于获得正确的实验结果．

The error of the result in measurement of internal resistance with sensitive current meter is relatively great. Both the minimum squere method and successive sets subtraction method have been used in this paper to calculate the experiment date set, and to show that it is helpful to obtain correct result of experiment by choosing date processing method from error discussion.
