| 摘 要： | 多数对多孔介质冻结过程的研究是建立模型借助于计算机技术给定数值解。笔者在借鉴现有数值模型的基础上，考虑多孔介质的内部特点，采用容积平均法建立数学模型，对无限大平板状多孔介质在第三类边界条件下发生的一维冻结过程中温度变化进行分析并加以实验验证。

| Abstract: | Most studies on freezing process of porous media are concentrated on numericat simulation taking advantage of computer technology. A numerical simulation using average volume method model was carried out to predict temperature variation during freezing of onedimensional infinity porous media. A comparison between the results of the model and experimental data was made. |
