Comparative studies on dynamic behavior of superconducting levitation system with consideration of flux creep;
针对磁通蠕动效应的超导悬浮动力运动比较研究
Based on Anderson's flux creep model, the counter direction hopping effect of the flux line is taken into consideration and a new general expression of irreversibility line (IL) is obtained.
基于 Anderson磁通蠕动模型 ,考虑磁通的反跳对磁通蠕动速度的影响 ,得出了超导体中不可逆线的一般表达式。
Numerical calculation based on flux creep model with logarithmic barrier U showed that the dependence of ac losses Q on the amplitude of ac field Bac is still governed by Q∝Bmac, predicted by the Bean model.
基于对数型位垒的巨磁通蠕动模型,我们进行的数值计算证明,交流损耗与交流振幅的关系在定性上是和临界态模型相同的,即与振幅的m次方成正比:Q∝(Bac)m。
