摘　　要：阐述了示波器法测磁滞回线实验的优点、特点,分析、解决了该法在实际操作中的常见问题,设计、改进了原理推导比较简洁的新电路,做了新旧电路的对比,得到了实验验证.Our thesis described the merits and feature of the experiment of hysteresis loop with oscillograph ately. On the basis of these analyses, we supplied concrete instructions and solution for the normal phenomena and anomalies. Furthermore, we devised a new experiment circuit in contrast with the applied one. Consequently, we made a comparison and instruction between the both circuits, which was validated when subjected to the experiment. H
