摘　　要：在归纳针对多孔结构表征的氮气吸附法、压汞法等传统方法和毛细管流动孔径分析法、热孔法、扫描电子显微镜观察法等现代方法以及现代分形分析理论的基础上,重点阐述了制革过程中皮革胶原纤维网络基质多孔结构变化的研究进展,同时介绍了多孔性结构对皮革性能的影响。充分了解并掌握制革过程中影响皮革胶原纤维网络多孔结构的演变因素,对优化制革工艺、提高化工材料利用率和改善皮革性能具有极其重要的意义。Based on the summarizing of traditional characterization methods of porous structure, such as nitrogen adsorption method and mercury intrusion method, and modern techniques including capillary flow porosimetry （CFP）, thermoporometry （TPM） and scanning electron microscope （SEM）, as well as modern fractal analysis theo- ry, the research progress of porous structure changing of collagen fiber network during leather making process was ex- plained emphatically. The influence of porous structure on leather properties was introduced. Understanding and grasping the effect factors of porous structure of leather collagen fiber network during leather making process is of great significance to optimize leather making technique, enhance chemicals utilization and improve leather pronerties.
