摘要
本文采用两种实验方法对比测量可知通常的导线连接其接触点的电阻 ,并由此进行分析 ,阐述在双电桥测量低电阻实验中四端扭接法的必要性。
BY comparing the measurements of two experimental procedures,the resistance at the junction point in the conventional mode of connection can be tested.Henceforth,the article analyzes the necessity of the mode of the 4-terminal connection in the experiment of low resistance measurement using the double bridge.
