We have developed a new approach, starting from the Frohlich Hamiltonian and by means of the unitary transformation with the perturbation treatment, to deal with the momentum-dependent spectral functions MDSF of electron-phonon coupling system. The approach takes care of the fact that only those electrons near the Fermi surface within a layer of width ph phonon frequency are scattered by phonons strongly. Our results show that the MDSF is mainly composed of two parts: the zero-phonon part and the one-phonon one. �
