摘　　要：对于Stokes方程求解问题,作者提出了局部绝对稳定有限元方法.该方法可以看成是Kechkar和Silvester方法从线性/常数元到任意混合元的推广,也可以看成是Douglas和Wang整体绝对稳定化有限元方法的局部稳定化改进.A locally absolutely stabilized finite element mathod for the Stokes problem is presented in this paper. This new method can be seen as an extension of Kechker and Silvesters＇ method from linear/constant elements to any mixed elements, also can been regarded as a locally stabilized modification of Douglas and Wangs method.
