摘　　要：分析了利用冲击电流计测量电容的过程中产生误差的原因,着重讨论了标准电容的取值对测量结果的影响。结果表明:标准电容值与被测电容值的差值越小测量结果的误差也越小。The source of error in the experiment of measuring capacitance by ballistic galvanometer was analyzed that we mainly discussed the influence of values of standard capacitance on measuring results.The results indicate the smaller difference between the values of standard capacitance with measured capacitance,the smaller error.
