摘要
研究砂土孔隙内水分蒸发的机理,提出了土层内水蒸汽的迁移模型,模拟分析了砂土内空气受外界不同气侯条件影响下的湿度变化特性.
The mechanism of evaporation in unsaturated sand soil is analysed. A mathmatical model to calculate the ralative humidity of the air in porous is proposed. The results of dynamic humidity distribution under the simulated natural climate conditions are obtained.
