| 摘 要： | 本文提出了多声子过程的强耦合超导理论,给出了能隙方程和Tc公式。结果发现,考虑电子多声子过程,高频声子对提高Tc有重要作用,单胞中对超导贡献的简并度数大,也有利于高Tc的出现。

| Abstract: | The modified Eliashberg equations and Tc formula are obtained by incorporating the effect of many phonons into the theory of superconductivity. The result of our analysis is that the high frequency phonon plays an important role in raising Tc, and the large number of degenerate degree contributes greatly to superconductivity as well. |
