The results show that the global degree, the homocentric degree and the mural uniformity of the plated ICF glass targets were nearly the same as those of the ICF glass targets before plating.

结果表明：对ICF玻璃靶丸进行化学镀处理，其球形度、同心度和壁厚均匀性都与化学镀前未发生明显改变，其饱和磁化强度和矫顽力分别为3.883×10^(-3)A/g和1.046×10^(-3)T。

Simulative results show that the electron beam can be transported in the unmagnetized plasma-filled for two reasons. The first, the plasma neutralizes the majority of the space charge forces within the beam. The second, radial electric field generated by electron beam interaction with the plasma leads the beam to converge along axis. By PIC simulation, we find that atomic mass of the background ion effects on the Characteristics of the plasma-filled devices.

非磁化等离子体填充的RBWO-FEL的模拟表明只有在一较窄的背景等离子体密度范围内，电子注才能良好传输，产生泵波及激光功率输出，并都存在有峰值功率点，同实验观测到的结果完全吻合；该范围内，电子注的传输是由于背景离子中和了注中径向发散空间电荷力及注在等离子体中产生的径向的电场使注在轴向汇聚。

The soft layer of ECC media usually possesseshigh saturation magnetization and also high demagnetizing energy density.

ECC介质由交换耦合的软磁层与硬磁层构成，它是通过软磁层与硬磁层的磁矩在磁化反转过程中的非一致转动来达到降低矫顽力的效果，而无外场时热反转仍为一致转动，因而能保持较高的热稳定性。

These results suggest that when the demagnetizing energy of soft layer is unavoidablethe application of high Ms soft layer can help to decrease the switching field,maintainthe thermal stability,improve the uniformity,reduce the thickness of interlayer andtotal recording layer,and will not worsen the signal to noise ratio.

研究结果说明当软磁层的退磁能无法避免时，使用较大饱和磁化强度的软磁层有利于降低矫顽力，保持热稳定性，提高介质的均匀性，减小中间层和记录层的厚度，并且对信噪比没有不良影响。

The influences of deposition time on the covercivity and saturation magnetization of electroless CoWP thin films were studied, and the surface topography, elemental composition, micro-structure and magnetic properties of CoWP thin films were tested respectively by FSEM , XRD and VSM.

研究了施镀时间对化学镀CoWP薄膜矫顽力和饱和磁化强度的影响，并利用场发射扫描电子显微镜、X射线衍射和振动样品磁强计研究了CoWP磁性薄膜的表面形貌、成分、微结构及磁学性能。

The iron hydroxide particles prepared above were coated with cobalt by surface adsorption-precipitation reaction. The low pH and Co〓 concentration of suspended system can prevent the nanoparticle from heterocoagulation. The saturation magnetization of MP particles with uniform cobalt hydroxide layer is 10％ higher than that of the α-Fe. And a close SiO〓 layer can improve the coercivity by about 92％.

铁黄粒子表面吸附-反应沉积钴过程中较低的pH值和浓度有利于形成均匀的钴氢氧化物包覆层，可避免形成异相凝聚现象，使比饱和磁化强度提高10％；表面包覆二氧化硅形成致密的薄膜，使矫顽力提高92％。

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 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。

The hollow Ni2 microspheres were prepared via the hydrothermal reaction of NiCl2 with aqueous ammonia at 140 ℃ for 12 h.

The split between the two groups can hardly be papered over.

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
