灵敏检流计内阻测量方法的研究

STUDY ON THE MEASUREMENT METHOD OF INTERNAL RESISTANCE OF SENSITIVE GALVANOMETER

本文提出了一种测量灵敏检流计内阻的新方法，即“准临界倍偏法”．对其进行了理论分析并得出了较为满意的实验结果．实验结果表明：与“半偏法”和“等偏法”比较，该方法具有测量简便、误差小、抗干扰能力强和工作效率高等一系列优点．

In this paper the new method measuring the internal resistance of sensitine galvanometer is advanced. That is quasi - critical multi -deviation method. Theoretical snalyze is carried out and ideal experimental/results are obfained. The experimental results indicate that aduantages of the method are that its measurement process is simple and convenient and mean error is small and interfering resistant is high compared the method against half - deviation method and equi - deviation method.
