摘　　要：固定实验条件,使得惠斯登电桥灵敏度是标准电阻的一元函数。再应用Origin8.0软件对实验数据进行曲线拟合,从而得到待测电阻、检流计内阻以及检流计灵敏度的数值。The sensitivity of Wheatstone bridge is only the function by standard resistance,when we fixed some experiment conditions.With origin 8.0 software,experimental data are fitted and the values of the unknown resistance,essential resistance and the sensitivity of galvanometer can be obtained.

关 键 词：惠斯登电桥 灵敏度 Origin8.0 曲线拟合
