本文从欧姆定律、伏安法的视角审视各种补偿法测电阻电路,实际上各种补偿法测电阻电路都是和伏安法一样按欧姆定律方式设计的。实践表明按从消除伏安法测电阻电路系统误差逐步推演出完全补偿法的测电阻电路,再讲授补偿法的原理的思路设计教学,收到了很好的效果。
本文從歐姆定律、伏安法的視角審視各種補償法測電阻電路,實際上各種補償法測電阻電路都是和伏安法一樣按歐姆定律方式設計的。實踐錶明按從消除伏安法測電阻電路繫統誤差逐步推縯齣完全補償法的測電阻電路,再講授補償法的原理的思路設計教學,收到瞭很好的效果。

It examines the resistance measurements by compensation method in new view of the Ohm ’ s law and voltammetry. In fact,the circuit of resistance measurement is designed on Ohm’ s law by compensation method the same as voltammetry. The teaching practice shows that the effect is good following the new idea that the compensation method is derived from eliminating the systematic error of voltammetry,and then teaching the principle of compensation method.
