摘　　要：用等偏法测得原始实验数据,运用最小二乘法原理进行处理,求得灵敏电流计两个基本参数——电流灵敏度和内阻,并与直接作图法进行比较;结果发现利用最小二乘法处理实验数据较之直接作图法更为精确。This paper uses equal amount of deflection to obtain primitive experimental data, uses the least square method principle to process galvanometer, obtain sensitive galvanometer＇s two basic parameters such as current sensitivity and interface resistance, and compares with the result gained by the direct graphic method. The results show that the experimental data processed by the least square method are more accurate than the data processed by direct graphic method.
