Abstract ： By taking into account the possibility of phonon mediation, we add the Hubbard model a term of attractive interaction between the electrons on nearest-neighbor sites. There is a competition between the electrons pairing and the antiferromagnetic correlation. Using the mean-field theory, we show that there exists the superconducting phase transition in the doped system.
