1) Thoron level
气土水平
2) horizontal soil column
水平土柱
1.
Principles and errors of measuring infiltrability with horizontal soil column and Green-Ampt model;
用水平土柱与Green-Ampt模型方法测量土壤入渗性能的原理与误差
2.
The processes of water diffusion in non-saturated soils and the relationship between water diffusion rates and water contents were simulated by horizontal soil columns from saline-alkalined wetland in Xianghai National Natural Reserve.
运用水平土柱入渗法模拟研究了盐碱化湿地土壤的水分扩散过程以及水分扩散率和土壤含水量之间的关系,结果表明:盐碱化可降低土壤的水分渗透性能,湿地10～20cm内土层水分渗透速度较其它两层小得多,下部土壤层次的水分扩散率高于上部土壤层,湿地土壤水扩散率随土壤含水量的增加呈指数增长变化的趋势,且表层土壤的增长曲线相对较陡。
3.
Based on the energy principle of water movement in saturated/unsaturated soils and the measured soil water distribution in horizontal soil column, modifications were made to the piston assumption of the soil water distribution in the Green-Ampt infiltration model.
该研究根据水流在水平土柱中运动的能量要求以及实际测量得到的土壤水分分布,对Green-Ampt模型中含水率分布呈活塞运动推进(即湿润锋内部土壤水分为恒定值)的假定进行了修正。
3) balanced harness of soil and water
平治水土
4) horizontal digging
水平掏土
