| 摘 要： | 在处理薄膜中的超导现象的理论时,London理论、Pippard理论和GL理论都有其局限性,因为这些理论都不能完全解释超导电性的本质。根据对超导薄膜临界磁场普遍适用的公式,结合实验测得的超导薄膜临界磁场在理论上应该具有非线性、非局域性的特点;分析了影响超导电性的各种要素,得出了London理论、Pippard理论下修正后的临界磁场的表达式;分析了GL理论下波函数分别为球面波和正弦波时临界磁场分布情况。

| Abstract: | It＇ s limited for London theory, Pippard theory, GL theory to deal with the theory of super - conduct pellicle. They can＇ t explain the essence of super conductivity. According to the formula applied to the common situation and combining the nonlinear and unlimited features of the critical magnetic field of super - conductive pellicle, the factors affected the super conductivity was analysed, then the expression that applied to the London theory and Pippard theory under mented was obtained. Meanwhile the situation of critical magnetic field under GL theory when wave functions are spherical function and triangle function were analased. |
