灵敏电流计实验的改进

On Improvement of Sensitive Galvanometer Experiment

在观察灵敏电流计线圈运动状态时 ,操作转向开关 (K1)时 ,总需要一定的时间 ,在这段时间内外电阻无穷大 ,给实验的观察和测定带来较大误差 。

During observation of motion of sensitive galvanometer it alwaystakes time to operate reversing switch(K1) in this a period of time external resistance is infinity ,so the error of obervation and measurement are caused in experiment.The paper will study the method improved,and it can improved accuracy.
