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.
