| 摘 要： | 本文从热湿迁移机理出发，通过在液相渗流中引入毛细滞后的影响，采用液相运动的最小梯度假设，建立了未饱和含湿多孔介质在考虑毛细滞后效应时传热传质的较普遍的模型理论．并对方程中的热湿迁移特性系数进行了分析，为进一步发展确定热湿迁移特性的有效实验方法提供了依据。

| Abstract: | Based on the Mechanism of heat and mass transfer and by using the minimum gradient theo-ry for unsaturated flow in capillary porous media, a general theory for heat and mass transfer in unsat-urated porous media cunsidering the effect of capillary hysteresis is established.In addition,the heatand mass transport properties in the equations are analysed,which provides a basis for developingeffective experimental method to determine the properties. |
