摘要
本文从《示波器法测绘铁磁材料的磁化曲线和磁滞回线》实验电路出发，定性定量地分析了电阻Ｒ１和Ｒ２的取值范围，对于提高教学效果提供了一定的参考．
The article begins from the circuit in the experiments which we survey and draw magnetization curve and hysteresis loop of ferromagnetic material by oscilloscope pellets, It will provide some references for improving the teaching efficiency through the qualitative and determine mount analysis of sampling scope from the resistances R1 and R2.
