摘要
给出了非均质土壤中考虑水动力弥散尺度效应的一维溶质运移两区模型。在初始浓度为零、半无限一维空间内常数通量边界条件下 ,推导出了可动区溶质浓度分布 Cm( x,t)和不动区溶质浓度分布 Cim( x,t)
In this paper the two region model of one dimensional solute transport through heterogeneous soils considering scale dependent dispersion is studied, and an quasi analytic solution describing the concentration distribution at the mobile region C m(x,t) and immobile region C im (x,t) is deduced under the initial concentration zero and a constant flux boundary condition of a semi infinite one dimensional space.
