摘　　要：考查了小粘性时非特征边界情况下MHD方程在边界附近的性质,说明速度在边界上不为零.源于之前非特征边界条件下不可压缩Navier-Stokes方程边界层的工作,证明了边界层的存在性,并得到了当粘性收敛于零时,MHD方程的解收敛于理想MHD方程的解.The goal of this article is to study the property of the MHD equations with small viscosity near the boundary when the boundaries are non-characteristic, i.e., to know that the velocity is not zero at boundary. Following the earlier works on the boundary layers for the incompressible Navier-Stokes equations in the case that the boundaries are non characteristic, the authors prove that there exist boundary layers and derive the convergence of the solutions of the viscous MHD equations to that of the ideal MHD equations as the viscosity tends to zero
