The direct hybridization mechanism for high T(?) superconductivity has beenproposed and studied by using the mean field approximation.A local singlet pairformed by media of hybridization between nearest-neighbor sites.The transition tem-perature

zero energy gap

and the specific heat jump as a function of dopingfraction

as well as the temperature dependence of energy gap

specific heat andthe thermodynamic critical field

have been calculated.
