求出了多孔拉伸薄板上粘性、不可压缩的MHD流动的精确解。施加了垂直于薄板的均匀磁场。通过相似变换，将控制高度非线性的运动偏微分方程化为常微分式。用待定系数(U.C.)对所得方程进行了求解。方法。并用拉伸变量法进行了数值求解。考察了流动参数哈特曼数M、吸注比S对速度、压力函数和壁面摩擦系数的影响。结果以表格和图形的形式呈现，以详细说明流型。
The exact solution is sought for a viscous, incompressible, MHD flow over a porous stretching sheet. A uniform magnetic field perpendicular to the sheet has been applied. The governing highly non-linear partial differential equations of motion have been transferred to ordinary differential form by using similarity transformations. The resulting equations have been solved by using undetermined coefficient (U. C. ) method. Also, the problem has been numerically solved by method of stretching variables. The effects of flow parameters namely Hartmann number M, suction/injection parameter S have been observed on velocity, pressure functions and skin friction coefficient. The results have been presented in tabular as well as graphical form to elaborate the flow pattern.
