自发磁化强度 meaning in English

spontaneous magnetization

So magnetic material will produce non - elastic shape change when it is pressed or drawn . additionally the strength changes of spontaneous magnetization benefits to detect distribution of stress
另外，作用在铁磁材料上的应力能使其自发磁化强度发生变化，为检测材料中的应力分布提供了依据。
When the stress at the tip of crack is inflicted on the m - type ferrite particle dispersed in matrix as a second particle , not only the toughness of composites will be pro ved because of the non - elastic area produced by the particle but also the strength change of magnetic field and the stress distribution in the structural ceramics will be detected by the strength of spontaneous magnetization varying while magnetic materials being pressed or drawn
这是因为当结构陶瓷中裂纹尖端的应力作用在弥散于基体内的铁磁体二相粒子上时，铁磁粒子不仅在裂纹尖端周围产生的非弹性区域使复合材料的韧性提高；而且还能利用铁磁材料在外应力作用下自发磁化强度发生变化的性质，通过测量复合材料在应力作用下磁场强度的变化，探测出结构陶瓷中的应力分布情况。
