摘　　要：对求解带有抽吸/喷注的幂率流体平板边界层的相似解方程进行了研究,利用Adomian分解方法得到了在不同的幂率下方程的近似解析解和相应的壁摩擦因数值,并通过对近似解所推出结果以及所得壁摩擦因数进行的验证,证实了本文提出的解析近似方法的准确性和可靠性.The similarity solution equation of laminar boundary layer flow with suction/injection in power law fluid was studied in this paper.The corresponding approximate analytical solutions and skin friction coefficients were obtained for giving power law exponents by the Adomian analytical decomposition technique.Moreover,the reliability and efficiency of the approximate solution and the conclusions obtained from the approximate solution were verified using numerical solutions.
