Since there have existed several models to describe the characteristics of HTS,such as perfect diamagnetic model、flux flow-creep model and critical state model, each has its advantages and disadvantages.

为此,我们实验测试了HTS块材与永磁间相互作用随空间相对位置变化,并基于HTS完全抗磁性和临界态模型构造的B(H)曲线进行模拟仿真,通过与实验结果的比较,力求寻找一种方便可行、较为准确及可靠的HTS块材与磁场间相互作用估算方法。

Three kinds of critical state models, such as Bean's model, Kim's model and Power model, are selected to analyze numerically the initial magnetic curve and hysteresis loop of Bi2223 high-T c superconductor, as an example, with a simple method.

利用三种临界态模型 (Bean模型、Kim模型和指数模型 ) ,采用比较简单的方法 ,以Bi2 2 2 3高温超导体为例 ,给出了平板状超导体的初始磁化曲线和磁滞回线的解析表达式 。
