摘要：

Based on approximation of the balance relation for convection-diffusion problems, finite difference schemes on rectangular locally refined grids are derived and studied. A priori estimates and error bounds in discrete H-1-norm are provided. Numerical examples demonstrating the accuracy of the schemes for a variety of model convection-diffusion problems are presented and discussed.
