摘　　要：对同一低电阻分别用伏安法、双电桥、双“单电桥”进行测量,几种方法的测量结果相当吻合。通过比较,认为双“单电桥”甲类方法测量电路直观简洁,便于操作,测量精度高。To measure the same low resistance with methods of Volt-Ampere,double bridge and double ‘single bridge’,we can get the same results. The last measurement is better than the others. The measuring circuit is simple and the measuring accuracy is suitable.

关 键 词：低电阻 伏安法 双电桥 双“单电桥”
