摘要
首先给出二维土壤溶质输运方程时间二阶精度的Crank-Nicolson(CN)时间半离散化格式,然后直接从CN时间半离散化格式出发,建立具有时间二阶精度的全离散化CN广义差分格式,并给出CN广义差分解的误差估计.
A Crank-Nicolson (CN) time semi-discrete racy for two-dimensional soil solute transport equations is crete CN generalized difference formulation with second formulation with second established firstly. And-order time accuracy is order time accu-then, a fully dis- directly founded from a CN time semi-discrete formulation with second-order time accuracy,and the error estimates of its solutions are provided.
