摘要
考虑了单位正方形区域上两相渗流驱动问题，研究了在非均匀网格上块中心差分混合元耦合格式，得到了对浓度的二阶离散Ｌ２—模误差估计。
The driving problems of the two phase vadose in the area of a unit quadrangle is considered The block centered FD and MFE schemes in a nonuniform grids is analysed A second order error estimation for the discrete L 2 norm of the concentration is obtained
