摘　　要：考虑Soret和Dufour效应,对Casson流体在可伸缩表面上,作磁流体动力学流动时的影响.首先导出相关的方程,然后用同伦法构造级数解.给出并讨论了速度、温度和浓度的场结果;在不同的物理参数下,得到并分析了表面摩擦因数、Nusselt数和Sherwood数的值;并验证了级数解的收敛性.The Soret and Dufour effects on the hydrodynamic flow of Casson fluid over a stretched surface were discussed.The relevant equations were first derived and then series solution was constructed by homotopic procedure.Results for velocity,temperature and concentration fields were displayed and discussed.Numerical values of skin friction coefficient,Nusselt and Sherwood numbers for different values of physical parameters were constructed and analyzed.Convergence of series solutions was examined.
