| 摘 要： | 本文运用了唯象的Ginzburg-Landau 理论研究了介观薄圆环的间隙性超导, 给出了在外磁场作用下超导圆环出现间隙性超导现象的尺寸相图. 这种间隙性超导现象只出现在尺寸小圆环中, 而且是超导圆环区别于超导圆盘的一个特征.

| Abstract: | Intermittent superconductivity for mesoscopic thin-film rings is investigated by the phenomenological Ginzburg-Landau theory. Phase diagram for intermittent superconductivity vs. ring dimension is given in the presence of an external applied field. The intermittent superconductivity exists only in the small ring, which is a feature for distingushing superconductive ring from superconductive disk. |
