摘要
本文研究了未饱和土壤中热、湿与盐分的复合迁移过程的机理和动态特性．建立了描述多相多组分热质迁移过程的动态模型和相应的微分方程组并进行了数值模拟，获得了土壤中温度分布、盐分分布和湿分分布的动态分布特性．模拟结果和实测值相比较，表明本文建立的模型是合理可信的．
篢he mechanism and the motional characteristics of moisture and salt migration, andheat transfer in unsaturated soil were investigated. A heat-mass transfer model was proposedand a set of governing equations was developed. By use of numerical method, the motionaldistributions of temperature, moisture and salt in unsaturated soil under different boundaryconditions were obtained. The comparison between numerical results and experimental datashow that the model developed is satisfactory.
