简要介绍了用X射线小角散射分析技术测定多孔固体材料中孔界面分形维数的理论,同时报道了应用这一理论对多种炭素材料和水泥石材料中孔界面分形维数的测定结果。结果表明,所有试样中孔界面均具有分形结构特征。
The theory of determining the fractal dimension of porous interface in porous solid materials by X-ray small-angle scattering analysis is briefly introduced. The fractal dimension of mesopores in a variety of carbon materials and cement stone materials is reported using this theory. The results show that all the pores in the sample have fractal features.
