摘　　要：In this paper, we study a kind of axial symmetry nonsteady flowing in bi-ological fluid mechanics. lt is of the strange character of nonlinear PDE. An effcientFEM analyses is presented. FEM schemes are established. Moreover, error estima-tions in L2 norm and H1 norm are obtained.In this paper, we study a kind of axial symmetry nonsteady flowing in bi-ological fluid mechanics. lt is of the strange character of nonlinear PDE.
