地下水水质污染问题数学模型的混合元—特征有限元方法

MCF Methods to the Contamintive Problem in Groundwater Quality’s Model

本文讨论并描述了地下水水质污染问题数学模型中的一类非线性耦合方程组的混合元—特征有限元方法，构造了问题的混合元—特征有限元全离散格式，利用椭圆投影及其误差估计。

A nonlinear hyperbolic parabolic coupled system is derived to describegroundwater quality contamination. The numerical method(Mixed finite element charac-teristic finite element method)is introduced. Two elliptic projections and their error esti-mates are gived. The fully time discrete scheme of the method is presented.The optimal or-der estimates in H￣'is derived for this scheme.
