We used the first equation of Ginzburg_Landau theory to study superconductivity with no magnetic field considered. We have obtained the effective mass m of Ginz burg_Landau equations, which has a special property, namely it can be negative. Some explicit expressions for different cases are derived, which are consistent with experimental data.
