【Abstract】 The Thermodynamic potential of the superconductions near the critical pointis obtained by the steepest-descent method in the one loop diagram approxima-tion,in which the effects of the intrinsic fluctuating electromagnetic potentialas well as the fluctuating order parameter are taken into account.The super-conducting phase transition is then predicted to be weak first order.更多还原
