| 摘 要： | 通过详细分析超导磁悬浮特征,论述了各理论模型与实际应用情况存在的偏离,其原因在于理论上为超导体设置边界,从而严重限制了超导体对外磁场的动态响应。为了避免这种缺陷,文中取自然边界,并将涡旋电流(VC)作为独立的微磁场源与外磁场相互作用,运用基本电磁场理论描述超导磁悬浮特征。经过严格推导,给出了超导磁悬浮系统的磁场分布表达式。对测量结果进行反演,有望为超导透析技术奠定理论依据。

| Abstract: | Through analyzing the characteristics of superconducting magnetic levitation, we discussed in detail the previous theoretical defects caused by the boundaries setting for the type-II superconductor. The reason is that the boundaries restrict severely the dynamic response to applied filed for superconductor. Based on vortex currents (VC), we adopt a natural boundary and regard them as some tiny independent magnetic origins to interact with the applied filed. By the strict mathematical inference, some formula... |
