导磁园柱筒的磁屏蔽和磁化力

The screening effect and magnetizing force of a permeable cylinder

依据工件材料的性质EMAT的换能机理主要有3种形式：洛仑兹力、磁致伸缩力和磁化力。

Based on the nature of the workpiece material to the mechanism of EMAT , there are three kinds of main forms : Lorentz force , magnetostriction and magnetization force .

磁化力F是加速渗碳体溶解和碳扩散的驱动力，通过推导可以得出单位体积力F的表达式。

The magnetization force F , which is the driving force for the accelerating of the dissolution and diffusion of the carbon , can be given by formulas .

一般而言，空心轴式的体积较小，而所需磁化力（磁动力）亦比伸出轴式为小。

Generally speaking , hollow shaft type of small volume , but the amount of magnetic force ( magnetic power ) also stretch out shaft type than for small .

相反，在伸出轴式离合器或制动器，磁性线圈与传动单元之间有小旷地空闲，所以需求较大的磁化力。

In contrast , in the outstretched shaft type clutch or brake , magnetic coil and transmission between units have small desert land idle , so demand greater magnetized force .

强磁场的磁化力和洛伦兹力通过控制初晶硅颗粒迁移行为来改变其在合金基体中的分布状态，通过影响凝固过程中的对流现象改变合金的凝固组织。

The results indicate that it is possible to control the behaviors of reinforced particles in the metal matrix by using intense magnetic fields in the solidification process of metal matrix composites .

本文从压磁效应的另一个方面&磁化对应力的影响，讨论了震磁问题。

From another aspect of piezomagnetic effect & magnetization influencing stress , this paper deals with the seismomagnetie questions .

利用Bitter粉纹法观察了未经磁化、受力程度不同的无取向硅钢片和20钢试件的磁畴结构，对比分析了应力对磁畴的影响。

The magnetic domains of silicon steel sheet and 20 carbon steel samples , which have subjected to various loads , have been observed with the Bitter method , and the effects of stress on magnetic domains of the two steels were analyzed comparably .

依据铁磁材料磁化，受力释放的噪讯，研制了利用磁弹噪讯技术检测残余应力的仪器。

The instrument for testing residual stress using magneto-elasticity noise technology is developed by means of stress states and releasing noises of materials under and altemating magnetic field .

岩石剩余磁化强度的应力效应

The stress effect on remanent magnetization of rocks

该磁化装置的提升力与其在工件中产生的合成磁场无对应关系，因此不能反映对工件的磁化能力。

The lifting power of the yoke was not relative to the magnetic field composed in the workpiece tested , so it could not reflect the magnetizing power of the yoke .

但同时也发现随着磁化方向与应力方向的偏离，或是随着磁化强度的变化，这种相关性会发生变化，在特定条件下甚至出现相反变化趋势。

But at the same time , it has been found that the correlation changes when magnetizing direction deviates from the direction of stress , or magnetizing strength increases , even a contrary trend will advent in a special situation .
