| 摘 要： | 本文在Einstein谱情形,从Eliashberg方程导出了一个超导临界温度公式。在μ*=0时,把它和Eliashberg方程的数值解进行了比较。在λ<Λ区域,它们符合得相当好。

| Abstract: | A formula of the critical temperature for superconductors with small λ is derived from the Eliashberg equation. The effective phonon spectrum is taken in the present paper as the Einstein spectrum. The values of Tc calculated from our formula are compared with the numerical solutions of the Eliashberg equation in the case of μ*= 0 and the agreement between them is fairly well in the region of λ<Λ. |
