摘　　要：Ｃｏｃｋｂｕｒｎ＆Ｓｈｕ［１］在１９８８年提出了一种ＴＶＢＲｕｎｇｅＫｕｔａ局部投影的间断Ｇａｌｅｒｋｉｎ有限元方法应用于Ｅｕｌｅｒ方程的求解，并取得了成功。文章将该方法进一步应用到ＮａｖｉｅｒＳｔｏｋｅｓ方程的求解。The RKDG method, proposed by Cockburn & Shu (1988), is developed into solution of N S equation, and the results are compared with exact solution of Burger equation with viscousity. The result of 2D problem has been also compared with the one obtained by solving Euler equation.
