摘　　要：本文用二维非中性库仑气体模型描述磁场中超导薄膜上的涡旋涨落，将中性库仑气体的自洽方程组推广到非中性模型，并求得其数值解．AbstractVortex fluctuation in superconducting film in a perpendicular magnetic field is described by 2 D non neutral Coulomb gas model. In the paper a set of self consistent equations for 2 D Coulomb gas are extended to the non neutral case. The charge unbinding cross over region is verified and re entrant behavior at low temperature is found and discussed.
