稳恒超导载流态正常─超导界面层的作用

On The Function Of Proper Superconducting Boundary-layer Under The Steady Superconducting Current-carrying States

研究了稳恒超导载流态条件下 ,正常超导界面层对超导载流子的作用。指出在正常超导界面层内存在着“类感应电场力”,其本质上是束缚电子对所受 Lorentz力沿超导体对称轴线的分量之和。在“类感应电场力”的作用下 ,束缚电子对质心定向运动速度由零增大到 1 0 3 - 1 0 4 ms- 1,使超导电流的熵小于正常电流的熵。正常超导界面层是熵变区。

This paper expounds the functions of the proper superconducting boundary layer upon the superconducting current-carrier under the condition of steady superconducting current-carrying states. It should point out,there exists the like induction electric field force within the proper superconducting boundary layer, whose nature is the division of Lorentz force on the binding electric pairs on the superconducting symmetry axle. Under the influence of the like induction electric field force, the velocity of the mass motion of the binding electron pairs increases from zero to 10 3-10 4 ms -1 , making the entropy the of superconducting current less than the one of the normal current. The variational region of the entropy lies on the proper superconducting bourdary layer.
