| 摘 要： | 本文以半无限土壤溶质运移的对流——弥散方程为例研究边界层运动规律。运用Laplace变换方法推导土壤溶质运移的边界层方程。数学分析表明边界层上溶质通量假设对于计算边界层运动距离和溶质浓度是可行的。边界层运动方程的一个重要应用是估算溶质运移参数，这个估算参数方法在数学上更简单、信息利用更全面，是一个值得研究和发展的新方法。

| Abstract: | The boundary layer movement of solute transport in a semi-infinite soil media is studied in this paper.Laplace transform method is applied to deduce the boundary layer flow equation for solute transport in soil.The mathematical analysis shows that the assumption of solute flux in boundary is valid in calculating the advance distance of boundary layer and solute concentration profile.The boundary layer movement equation is applicable in estimating the parameters of solute transport. |
