摘　　要：多孔介质结构特征是研究多孔介质流动、传热、传质和化学反应的基础。首先介绍了主要的多孔介质的结构特征及其理论实验研究方法,对比了其优缺点。其次,对目前文献获得的土壤、岩样、水泥和煤的主要结构特征参数进行了分类归纳。最后,对目前多孔介质结构的分形研究成果进行了综述,对各种分维数进行了分析和整理。可以看出,目前对多孔介质结构研究还只是针对某个学科的某种或某类多孔介质,而且集中在很少的几个结构特征参数,系统研究很少,难以从整体上把握多孔介质的共性特征和差异性规律。Porous medium structure characteristics are the basis study of porous media flow,heat transfer,mass transfer and chemical reaction. Firstly,the experimental and theoretical research methods of structure characteristics of porous media were introduced and analysed the pros and cons of these methods. Secondly,structure characteristics parameters of soil,rock,cement and coal of existing literatures have been sorted. Finally,fractal research of porous media have been reviewed and all kinds of fractal dimension have been analysed. It can be seen that the structure of porous media studying only focus on some kind of porous media and focus on few of structure characteristic parameters and system research. It is hard to overall grasp the common and difference rule of porous media.
