摘要：

The spin fluctuation effect on the electron-phonon coupling factor has been calculated. The system is considered to be two-dimensional and we consider two different models which describe the spin fluctuations. These models correspond to strongly correlated electron systems. The effect of disorder introduced by nonmagnetic impurities is investigated.
