摘要
多孔介质中的控制释放由边界积分-常微分方程描述,溶质迁移由带第三类边界条件的对流扩散(含机械弥散)方程描述,构造了这一非线性耦合问题的有限元半离散格式,利用先验估计理论进行了收敛性分析.
The process of controlled-release in porous media was governed by a boundary integral-ordinary differential equation, while the process of spread was characterized by a convection-diffusion （with mechanical dispersion） equation with a boundray condition of the third type. A finite element scheme was proposed for solving the coupled nonlinear system. Convergence was analysed by a priori estimate method.
