摘要
本文讨论了多孔介质中完全可压溶混驱替问题的特征—差分方法。对压力和浓度方程构造了基于二次三角形或二次矩形插值的特征—差分格式，并给出了差分格式的离散Ｈ￣１及最大模误差估计。
The finite difference method for compressible miscible displacement in porous media is considered in the paper. The characteristic difference schemes based on quadratic triangle or quadratic rectangle interpolation for both the pressure equation and the concentration equation are constructed , and the discrete H￣1 and L￣∞ error estimates of the scheme are presented.
