摘　　要：通过实验分析用冲击电流计测量电阻时误差与标准电阻与待测电阻阻值差异对冲击电流计测量电阻误差的影响,发现标准电阻与待测电阻阻值相差不大时,冲击电流计测量电阻误差就小,反之就大。Autor analyses the impact of the difference between the values of resistance of the standard resistor and the measuring resistor on the error made by an impulse amperemetre. The experiment shows that the error varies with the differences between the values of resistance. Less error will be found when the difference is not great. On the contrary, greater error will occur if the difference is lager.
