摘要
本文研究地下水水质污染理论中的一类非线性双曲一抛物耦合方程组的混合元一特征有限元方法，给出两类椭圆投影及其误差估计，构造出混合元－特征有限元全离散格式，证明了格式在Ｈ１模度量意义下的最优阶估计。
In this paper,a nonlinear hyperbolic-parabolic coupled system is derived so as to describegroundwater quality contamination,A numerical method(mixed finite element and characteristic finite element combined method)is introduced.Two elliptic projections and their error estimates are given,Afull time discrete scheme of the method is presented.Optimal orderestimates in H' are proved for this scheme.
