分形理论是非线性科学研究中十分活跃的一个分支,为定量地描述和表征许多复杂体系提供了强有力的工具。介绍了分形理论的基本概念、规则分形、不规则分形及其分形维数的主要测定方法,综述了近几年来分形理论在多孔材料领域应用的研究进展,特别是分形理论在多孔材料的浸透性、传热特性、扩散性以及催化剂等方面研究成果,综述表明分形理论在多孔材料研究中具有广阔的发展前景。
Fractal theory is a very active branch of nonlinear scientific research and provides a powerful tool for quantitatively describing and characterizing many complex systems. This paper introduces the basic concepts of fractal theory, the rules fractal, irregular fractal and fractal dimension of the main measurement methods, reviewed in recent years the fractal theory in the field of porous materials applications research progress, especially the fractal theory in the permeability of porous materials , Heat transfer characteristics, diffusivity and catalyst research results show that the fractal theory in the study of porous materials has broad prospects for development.
