摘要：
We have calculated exactly the critical temperature, within the conventional Eliashberg framework, for realistic couplings. Our more precise analytic calculation leads naturally to a Tc higher than that given by McMillan's formula, which is generally used. We give an accurate formula for Tc in the coupling region λ≤1. © 1995 The American Physical Society.
