摘　　要：研究泊松方程外区域问题的高阶近似人工边界条件，并给出了利用此人工边界条件时有限元逼近的误差估计式。In this paper,a high-order approximate artificial boundary condition of Poisson equation with an exterior domain is investigated,and the error estimates for the solution of finite element approximation,which is based on the approximate artificial boundary condition,are given.

关 键 词：近似人工边界条件 有限元逼近 无界区域 误差估计 泊松方程 边值问题 外区域问题
