中文摘要：

含纳米孔的天然矿物岩石材料的吸附和催化性能对于表生地球化学过程、材料加工、应用及煤炭开发利用等方面均有着重要意义。本文对比分析了各种纳米孔表征技术，重点介绍了基于吸附等温线的纳米孔研究方法。对三个典型样品等温线数据的模型计算表明，应根据材料中孔的形态（平行板状孔、球形孔和圆柱形孔）选择模型，不同类型孔所对应的计算方法和参数有很大差别。表征材料表面能量均匀的样品可首先考虑采用DFT法；HK法一般只作为定性研究方法，BJH方法受样品本身性质参数的影响较小，且计算简单。可广泛应用于介孔材料的孔径分布的表征。

英文摘要：

The characteristics of adsorption and catalysis of the nano-pores bearing natural rocks and minerals play an significant role in the fields of surface geochemical process, coal development and application, material processing and application. Various kinds of techniques for characterizing nano-pore have been compared and analyzed in this paper. Especially, this paper has introduced the nano-pore research method based on the adsorption isotherm. The computation results of adsorption isothermal models for three typical samples indicate that it is very important to select right type of model based on the shapes of major pores （slit pore, sphere pore or cylinder pore） in materials, because the computation methods and parameters of various models corresponding to different pore types are quite different. When the surface energy of the sample is relatively even, the DFT method is a good choice. The HK method is usually used for qualitative analysis. The BJH method could be widely used to compute the characteristics of the mesopore size distribution as it is relatively small influenced by the property parameters of the samples with simple computation process.
