SEMI ANALYSIS METHOD AND ITS ERROR ESTIMATION
半解析法及其误差估计

In this paper we propose a method which associates the classical analysismethod with the recent finite element method (i. e. in regular domains and irregular onesanalysis method and finite element are used respectively.) for solving elliptic equations. We alsogive the error estimation in this method and establish the following important result: the semianalysis has much less degrees of freedom than the finite elements under the same requirementfor aceuracy.
