| 摘 要： | 在自然多子孔介质参数分析的基础上构建了多子孔介质子孔道网络模型，对其干燥过程中的湿分迁移机理进行了分析。采用Matlab软件模拟恒温缓慢干燥过程，并进行了多子孔介质干燥实验。结果表明，基于孔道网络模型的模拟方法能较好地模拟多孔介质干燥过程，孔道尺寸分布对介质内的相分布影响显著。

| Abstract: | Based on structural parameter analyses, a natural porous medium was described by pore
network model. Theories of moisture transfer in the model during drying were also researched.Drying of pore network was simulated in Matlab platform. The results showed that inner structural parameters of porous media, such as pore size distribution, have a notable influence on its drying process. |
