摘要
这篇文章讨论了有限元情形下，粘性不可压流动的全离散非线性Ｇａｌｅｒｋｉｎ方法，此外，给出了用非线性Ｇａｌｅｒｋｉｎ方法进行的数值试验结果，和通常的Ｇａｌｅｒｋｉｎ方法比较，非线性Ｇａｌｅｒｋｉｎ方法是一种稳定性好，计算量少以及逼近精度高的数值方法。
This paper discusses the full discrete nonlinear Galerkin method of viscous incompressible flow in the case of finite element. Moreover, we give the results of numerical tests performed with the full discrete nonlinear Galerkin mtehod. Comparisons are also made with the usual Galerkin method.
