摘要
研究出现了地下水渗流理论中的一类带混合边界条件的地下水污染的数学模型, 这是一个非线形抛物型耦合方程组的混合初边值问题, 构造了四种全离散 Galerkin 有限元格式, 讨论了格式的稳定性, 最后给出数值数例,
A nonlinear coupled system with mixed boundary conditions is derived to describe ground water pollution It is a initial boundary problem of nonlinear parabolic coupled system.Four full discrete Galerkin FEM schemes are established.Stabilities of these schemes are analyzed Finally,several numerical examples are given.So it shows the method is correct.
