摘要 该文给出了关于速度-压力型非定常Stokes问题的一个矩形Crouzeix-Raviart型各向异性非协调有限元的变网格逼近格式.并用一些新的技巧和方法导出了各向异性网格下的有关速度和压力的最优误差估计. This paper is devoted to the study of rectangular Crouzeix-Raviart anisotropic finite element method with moving grids for velocity-pressure mixed formulations of the nonstationary Stokes problem in 2-D. Anisotropic error estimations of the velocity and the pressure are derived based on some novel techniques.
