| 摘 要： | 在“灵敏电流计的特性研究”实验中,采用测量电流计内阻的传统方法“半偏法”,该方法重复测量结果存在较大误差。本文采用改进后的实验方法“变偏法”测量内阻,并用多点测量取平均的方法进行数据处理,明显减小了实验误差。

| Abstract: | In the experiment of the characteristic research of the sensitive galvanometer,letting the(angle) of the needle being half of the full size(ANHF)is used to determine the internal resistance of the(galvanometer).There are rather large errors in repetition experiment by this way.In this paper,an improved(method) that lets the angle of the needle be various point of the full size(ANVF) is adopted,the measuring errors are reduced. |
