摘要
本文在介绍直流双电桥原理基础上,主要讨论了四端钮电阻法消除接触电阻和连线电阻的原理和使用方法,并给出了几种提高微小电阻测量准确度的实用方法。这对于正确使用直流双电桥测量微小电阻有重要借鉴意义。
This paper is on the introduction two bridge principle foundations of direct current . discuss 4 ends mainly Niu resistance law eliminate use method and the principle of contact resistance and company line resistance, and have given some kinds of practical methods that raises small resistance accuracy. This have important reference for using the two bridges of direct current correctly to measure small resistance meaning.
