摘　　要：分析了微极流体朝向加热伸展平面的磁流体动力学(MHD)驻点流动,考虑了粘性耗散和内部产热/吸热对流动的影响.讨论了指定表面温度(PST)和指定热通量(PHF)两种情况,采用同伦分析方法(HAM)求解边界层流动和能量方程.通过图表的显示,研究了感兴趣物理量的变化.注意到高伸展参数时解的存在与外加应用磁场密切相关.The magnetohydrodynamic（MHD） stagnation point flow of micropolar fluid towards a heated shrinking surface was analyzed.The effects of viscous dissipation and internal heat generation /absorption were taken into account.Two explicit cases of prescribed surface temperature（PST） and prescribed heat flux（PHF） were discussed.The boundary layer flow and energy equations were solved by employing a homotopy analysis method（HAM）.The quantities of physical interest were examined through the presentation of plots/tabulated values.It was noticed that existing of solution for high shrinking parameter was associated closely with the applied magnetic filed.
