Abstract Based on the new superconductivity mechanism proposed by Liu and the mobile OPσ hole-localization mechanism for the system Y1-xPrxBa2Cu3O7-y, this paper first time gives a microscopic theoretical curve of Tc vs. x, and the dependence of ratio of energy gap at T= OK over Ti on Tc. The result shows that the mobile O. hole-localization mechanism is better than all other mechanisms including the pair-breaking mechanism, the hole-filling mechanism, and the c...
