查询词典 coercivity

In the range of this temperature, the coercive mechanism of NdDyFeB and NdDyFeBSn have been analysed with Gaunt's model on the basis of magnetic viscosity parameters. The coercivity of the former is controlled by weak pinning of domain wall, but the latter is determined by strong pinning.

根据磁后效测量数据，进一步用Gaunt的钉扎模型分析NdDyFeB及NdDyFeBSn合金在150℃以上的矫顽力机制，发现此时，前者的反磁化过程由畴壁弱钉扎控制，而后者由畴壁强钉扎控制。

The result shows that the mechanical strength and the thermal stability of bonded hybrid magnet are improved markedly with addition of ferrite in Nd-Fe-B powder,whereas its magnetic performance is reduced slightly.And the temperature coefficient of coercivity with zero is obtained in hybrid magnet with 87% ferrite and 13% HDDR Nd-Fe-B.Due to the magnetic dipole field between the differe...

实验结果表明：随着铁氧体磁粉的加入，复合磁体的磁性能虽略有降低，但其力学性能及热稳定性均有大幅度改善，特别是在铁氧体含量为87%时，复合磁体内禀矫顽力温度系数为零；不同磁粉间静磁场的存在，使得复合磁体在铁氧体含量低于70%时，其磁性能大于平均值，而大于70%时则小于平均值。

The M-H behavior has displayed a ferromagnetic hysteresis loop with a wasp-waisted shape, which constricted in the middle section, while wider at above and below section.Further, various amount (1, 3, 5%)of NdFeB were mixed with Ni-Zn ferrites. The M-H behavior has shown markedly different coercivity and wasp-waisted hystsresis.

为了进行本研究，在样品制备上系以燃烧合成法制备奈米级镍锌铁氧体软磁磁粉，并与市售微米级铷铁硼硬磁磁粉加以均匀混合，最后压制成软硬磁复合之块材，并经由震荡样品磁性量测仪对软磁、硬磁与复合磁材加以量测以描绘出其磁滞曲线。

It is caused by radiation, power, soft particle sensor, Gaussian, coercivity magnetic, self-energy, the resonance spectrum composed of a combination of its design parameters and manufacturing process of the two patents in the world to be protected.

它是由辐射、动力、软粒子感应、高斯、矫磁力、自供能源、共振谱组成的结合体，它的设计参数及制造过程两项专利在全世界受到保护。

The results show that with the increase of deformation strains and thinning of Fe-Cr fibers, the saturation magnetization are about 140 A·m2/kg constantly, and the remanent magnetism and coercivity increase gradually.The magnetic properties of Fe-Cr fibers are invariant when the Fe-Cr fibers were preserved in absolute alcohol or air for more than 1 a. After Fe-Cr fibers heated in air at temperature higher than 300 ℃ for 1 h, the Fe-Cr fibers transform from ferromagnetic α-solution to paramagnetic2O3, and the saturation magnetization of samples decreases remarkably. With the increase of deformation strains, the thermal stability of thinner Fe-Cr fibers decreases.

结果表明：随着变形量的增大和Fe-Cr纤维的细化，纤维的饱和磁矩基本恒定(约140 A·m2/kg)，而剩磁和矫顽力则逐渐增加； Fe-Cr纤维在无水乙醇和空气中储存一年以上，磁性基本保持不变； Fe-Cr纤维在空气中经300 ℃以上加热1 h后，逐渐由铁磁性的α-固溶体转变为顺磁性的2O3，饱和磁化强度显著下降；且随着变形量的增大，较细Fe-Cr纤维的热稳定性较差。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
