The purpose of this research is to study the upper critical field (H c2 ) of two-band superconductors by two-band Ginzburg -Landau approach. The analytical formula of H c2 included anisotropy of order parameter and anisotropy of effective-mass are found . The parameters of the upper critical field in ab-plane( but it has an unusual temperature dependence. Askerzade [10] study H c1 (T) and H c2 (T) for MgB 2 and nonmagnetic borocarbides by using the isotropy two-band Ginzberg-Landau model. He shows the complicate formula of critical magnetic field. In the H c2 consideration, his formula is less fit to experimental data than Drechsler 's [11]. In the recent work of Dao and Zhitomirsky [12] ,they study the effect of angular and temperature on upper critical field of MgB 2 determined with the anisotropy two-band Ginzberg-Landau theory. They found that the temperature variation of the ratio of two gaps is responsible for the upward temperature dependence of in-plane H c2 as well as for the deviation of its out-of-plane behavior from the standard angular dependence.In this paper, we study the upper critical magnetic field( 2 c H ) of anisotropy two-band swave superconductors by Ginzburg-Landau theory . We can find the formula of H c2 included anisotropy of order parameter and anisotropy of effective-mass . The upper critical field in abplane( ab c
