| 摘 要： | 孔材料的研究是当今热点问题之一，而关于孔的结构特性如比表面积、孔容、孔尺寸及分布等相关参数的确定，对于一些研究者可能存在着认知盲区.以实验室自制的孔材料为例，应用Nova 1000e型比表面积测试仪进行相关测试，并采用不同方法获得材料的孔结构参数.试验结果表明，非定域密度泛函理论（NLDFT）和骤冷固体密度泛函理论（QSDFT）可获取较为全面的材料孔结构参数，分析过程简便快捷.

| Abstract: | The study of porous materials is a hot topic nowadays. How to determine the porous structural characteristics such as specific surface area, pore volume, pore size, and its distribution, is probably, still an ambigous cognition for some researchers. The Nova 1000e specific surface area analyzer was used to analyze some porous materials prepared by our laboratory, and the porous structure parameters of materials were obtained by different methods. The results showed that the nonlocal density functional theory(NLDFT) and the quenched solid density functional theory(QSDFT) can be used to obtain more comprehensive parameters of the porous materials structure, and the analysis process was simple and fast. |
