水平入渗条件下溶质含量对土壤水分运动的影响和土壤水盐运动综合扩散系数D_(sh)(θ)的测定

A Analysis of Water-Salt Transfer and Measurement of Combined Diffusion Coefficient D_sh(θ) in Non-Saturated Soil for Horizontal infiltration

本文对土壤水非饱和条件下的水盐水平运移作了理论分析和试验观测。根据试验数据和数学求解得出计算综合扩散系统的计算公式,给出了观测扩散系数D_(sh)(θ)的方法。

In this paper, a theoretical analysis and laboratory test of water-salt transport in nonsaturated soil for horizontal infiltration are developed Based on the calculation formula found from experiment data and analytical solution, the combined diffusion coefficient Dah(θ) are measured.
