摘　　要：针对实验中造成困难的原因改进实验电路、实验仪器和实验方法,采用数字电压表测量和显示电势差的大小和正负,分别进行粗调和细调.调节的原理明确,使电桥平衡的调整简单、直观、易行.The laboratory instruments, experimental circuits and experimental methods are suggested to be improved aiming at problems in experiment. Digit voltmeters displaying positive or negative electric charge, are advised to be adjusted roughly or precisely to measure value of potential difference. The principle of regulation makes the adjustment of bridge equilibrium simple, visual and easy.
