摘　　要：本文介绍了用冲击电流计测电容时，开关漏电对测量的影响及改进方法。最后简要指出用比较法测量一个量值与标准电容相差较大的电容时，产生系统误差的原因。This paper presents the effect of electrical leakage on the measurement in measuring capacitance by ballistic galvanometer. Finally in brief the causes are stated of the occurrence of system error in measuring a measured value which is different from the standard capacitance by comparative method.
