摘      要：The Ginzburg-Landau equations are microscopically derived for an anisotropic(d+s)-wave superconductor by assuming a non-Fermi-liquid normal state characterized by a nonvanishing exponentα.The transition temperature Tc as functions ofαand the anisotropic parameter g which measures the ab anisotropy is *** is found that the anisotropic effect,which results in the enhancement of T_(c) and the nonzero bulk value of the s-wave order parameter,is strengthened due to the non-Fermi behavior.
