自发磁化 meaning in Chinese
spontaneous magnetization
Examples
- 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。 - Although the increment of the residual magnetism on the object after every cycle of magnetization - demagnetization process is very small , with the increase of the cycle index the object must be finally magnetized intensely and spontaneously
虽然每次磁化一退磁过程之后物体上的剩磁增量非常微小，但随着循环次数的增加该物体最终必然被强烈地自发磁化。 - 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。 - According to faraday law on electromagnetic induction and the difference of the magnetic energy of ferromagnetic materials in their magnetization and demagnetization , it is clarified that the swing , vibration and periodic translational reciprocation of any object made of ferromagnetic material in geomagnetic field must cause spontaneous magnetization of the object itself
摘要依据法拉第电磁感应定律和铁磁性物质在磁化一退磁过程中的能量差异，阐明了铁磁性物体在地磁场中的摆动、振动和周期性往复平动都会引起该物体的自发磁化。 - For example , when magnetic material being pressed , magnetic domain , direction and strength of spontaneous magnetization will vary . this phenomenon is called effect of pressing magnet . whichever rearrangement of magnetic domain or direction change of spontaneous magnetization will induces extra shape change of material
如对铁磁材料施加应力时，往往会导致磁畴、自发磁化方向和强度发生变化，这一现象称之为压磁效应，由于得益于压磁效应的作用，不论是磁畴重新排列还是自发磁化方向发生变化都会引起材料额外的形变，因此在一定应力的作用下铁磁材料能产生非弹性变形。
