本文用示波器法通过对不同铁磁材料磁滞回线和基本磁化曲线的观测及描绘,研究其磁滞特性,得到了磁滞特性更直观、容易理解、易于判断及有效提高测量结果的精度精确的数据给出了实验结果的影响因素及相应的实验结论,为铁磁材料磁滞回线实验的研究,磁滞特性更直观、容易理解、易于判断及有效提高测量结果的精度精确的数据及其应用提供了可靠依据。

The experimental and theoretical explanation of the loop-line measure of hysteresi-s characteristic in ferromagnetic materials is the basis of the fie-ld application of industries、biomedicines and military matters. In the loop-line measure of hysteresis characteristic,how to rapid the directly perceived understandable and improve the accuracy of the measurement results is a key point.It introduces that how to watch and measure the hysteresis loop-line and the basic magnetization curve with oscillograph and researched the properties of h-ysteresis characteristic, and the influencing factor and the experimental result and the experimental conclusion.This laid the foundation for the experimenta-l study of hysteresis characteristic in ferromagnetic materials and for the too-re ac-curate ex-Perimental data and appolication.
