The Advection-Dispersion Model of Reaction Solute Transport Through Soil and Its Analytical Solution

给出了同时考虑随深度变化的一阶降解和随深度变化的线性平衡吸附时 ,一维反应溶质运移的对流 -弥散方程。在初始浓度为零 ,半无限一维空间内第三类边界条件下 ,利用L aplace变换等数学方法推导出了该方程在 L

In this paper the advection dispersion equation of one dimensional reaction solute transport through soils with depth dependent first order degradation and depth dependent linear equilibrium sorption is studied Also, the analytical solution of the advection dispersion equation is deduced in Laplace space using Laplace transform and other mathematical methods under the initial concentration zero and the third boundary condition of a semi infinite one dimensional space.
