摘要：

Ginzburg-Landau equations for superconductors with both s- and d-wave coupling in the presence of nonmagnetic impurities are derived from the Gorkov equation microscopically. The impurity effects on the critical temperature of the mixed s+d symmetry superconductor, as well as the coexistent phase, are explored by using these derived equations.
