Analysis Of Several High-precision Unit And The Stokes Problem The Second Format

In this paper, we focus on the study of two problems.firstly, we analyze several important high accuracy elements proposed by using double set parameter method, and get some very usefull conclusions. Secondly, we construct a new triangular Hermite Type with formulation for mixed stokes equastions with order O(h2):This formulation has the advantages of simple structure and fewer degrees of freedom.
