And in the ( t , h ) phase diagram there is a tricritical point , at which the two boundary lines of the paramagnetic and ferromagnetic regions merge )不为零。 ( t , h )相图存在一个动力学三相点,顺磁区和铁磁区的边界线在这点开始汇合。
It ) ensures effective and amazingly quick stoppage for leakage of all carriers of transportation from all walks ( tank cars for dangerous articles , pipelines , ship body and paramagnetic object shells ) under different pressure 并且对于不同行业不同压力下的各种运输载体(危险品运输罐车、管道,以及舰船壳体等亲磁物体外壳)的泄漏,均能进行神速有效的封堵!
As to the paramagnetic ergag , the whole maganetization is zero . the crystal energy levels will split further when the magnetic field is parallel to the especial four directions . we - gain the according wave function and the magnetization changing with the magnetic field 考虑了外磁场沿晶体四个方向磁化时,晶场能级的进一步劈裂以及得出了其相应的波函数,从而分析了不同磁化方向磁化强度随外磁场的变化关系。
The influence on the magnetism and the electron spin resonance ( esr ) over a wide range of composition and temperature have been studied systematically . an obvious symmetric esr signal with a lorentzian lineshape in the paramagnetic regime is observed 本论文边过选择磁性离子替代,着眼点在于讨论衫杂离子的磁性效应,实验发现掺杂使样品的磁结构发生变化,且在低温时出现磁化强度峰,用掺杂离子自旋旋转对此进行了解释。
Long tr images show greater signal heterogeneity within the lesion core as a function of increasing te , probably because of the paramagnetic properties of hemorrhage : the main magnetic field is locally augmented by paramagnetic material and therefore a susceptibility difference is produced 长tr影像作为一种增加功能的te ,对病变中心显影更多的不均匀高信号区,这可能是源于出血产生的顺磁效应,即主要磁场的局部由于顺磁材料产生的磁性差异产生的一种结果。
The vector magnetic potential of a system consisting a line electric current and an infinite long magnetic dielectric column is calculated with the method of separation of variables and method of images , it is pionted out that the vector magnetic potential of a system consisting a line electric current and a magnetic dielectric plane , an ideal paramagnetic column , a superconductor column , and a line electric current in homogeneous magnetic field can all be deduced from our calculation 摘要用镜象电流法和分离变量法计算了线电流与无限长磁介质圆柱系统的磁矢势,指出线电流与无限大磁介质分界平面、线电流与超导体圆柱、均匀外磁场中有磁介质圆柱系统时的磁矢势都可以由线电流与磁介质圆柱系统的磁矢势的极限情形给出。
