| 摘 要： | 基于Norris方程和Bean临界态模型,考虑薄膜超导体内的磁场和电流密度分布特性,通过解析求解的方法推导出薄膜超导体在传输外加电流时其内部的磁场和电流密度以及传输交流损耗的解析表达式,从定量的角度研究超导体截面几何形状对传输交流损耗的影响.结果表明薄膜超导体边缘处的剧烈变化的磁场和电流的分布以及无场区的电流承载能力是...

| Abstract: | Based on Norris equations and Bean model,by considering the characteristics of magnetic field and current density in thin film,the magnetic field and current density in thin film are analytically derived,as well as the transport ac losses.The effect of the geometry of thin film on the transport ac losses is studied quantitatively.The results indicate that the dramatic change of magnetic field and current density at edge of thin film and the current capacity of the field-free region are the main reasons whic... |
