球壳超导体屏蔽系数的研究

Discussion on the shielding coefficient of superconductive spherical shell

屏蔽是电磁兼容的重要方法之一。通常用导体材料作屏蔽体 ,而用超导体作屏蔽体有更多的优越性。文章从 Maxwell方程和 London的超导二流体模型出发 ,推出了球壳超导体的屏蔽系数。

The shielding coefficient of superconductor in the shape of the spherical shell is derived on the basis of Maxwell's equations and London's two-liquid model. Some cases of superconductor shielding have been discussed in this paper.
