摘　　要：灵敏检流计内阻的测量是电磁学实验中的一个常规实验,在实验过程中,测量得到的内阻误差往往较大。文章就灵敏检流计的测量原理和误差产生的原因进行分析和讨论,提出了减小测量误差的具体措施,在一定程度上提高了内阻的测量精度。Surveying the internal resistance of the sensitive galvanometer is a electromagnetism experiment which is routine and complicated. The measurement error is large in the experiment. We analyze and discuss the measuring principle of a sensitive galvanometer which causes error, at the same time, put forward the concrete measures for decreasing the measurement error in order to improve the measuring accuracy of the internal resistance.
