摘要：
New mixed boundary conditions to the Ginsburg-Landau equations are found to limit the critical temperature (T-c) of high-T-c superconductors. Moreover, the value of the pseudogap in these superconductors can be explained by using the method. As a result, the macroscopic approach is proposed to increase T. of cuprate superconductors.
