摘要：
An infinite element method for solving elliptic equations with variable coefficients is presented in this paper. For those solutions which possess singularities, very accurate singular numerical solutions can be obtained with a small scale of computation; besides, it is unnecessary to know the order of singularity of the solutions or the analytic expressions of particular solutions in advance. A numerical example is given in contrast with the finite element method.
