摘　　要：1前言 考虑在R^2上一个有界单连通域Ω内的某种流动，该区域具有Lipschitzian边界P。设f∈L^2(Ω)~2,正的函数η∈(0.∞)。An revised mixed finite element method is developed for the quasi-Newtonian flow obeying power law. We prove that the divergence of velocity, which is obtained by this formulation, is optimal order convergent, and this formulation is the unique one having such feature forthis kind of flow till now.
