摘要：

The k, k(1) dependence of spectral function alpha(2)F(Omega, k, k(1)) is calculated based on the extended two story house model in which carriers itinerate in the region of local antiferromagnetic ordering composed of the localized spins. The following results are obtained: (1) d-wave pairing occurs even for the phonon mechanism; (2) the out-of-plane phonon modes contribute to the superconductivity in cuprates while those like breathing modes do not contribute significantly; and (3) the electron-phonon interaction in CuO5 type cuprates is stronger than in CuO6 type cuprates.
