摘要	On basis of Fie and Cui [W.-m. He, J.-z. Cui, A pointwise estimate on the l-order approximation of G(x0)(epsilon), IMA Journal of Applied Mathematics 70 (2005) 241-269.], we propose two kinds of effective finite element algorithms to obtain numerical approxinnations of Green function G(x0)(epsilon) defined in R-2 based on the method of multiscale asymptotic expansions; we present their pointwise error estimates and analyse their computer memory and CPU timed finally, we report results from numerical experiments.
