摘要 通过解析吸附等温线研究了天然斜纤蛇纹石的中空纳米管特征 ,与电子显微镜的分析结果比较 ,证明氮气吸附法是表征天然斜纤蛇纹石的中空纳米管内径特征的有效方法。该方法可以获取较大量样品的内径大小、分布和变化的特征信息 ,对其特殊理化性能的研究有特别意义。与其他表征方法结合可获得更完整的中空管参数 (包括外径 ) 。 With the physical gas adsorption, the inner diameter of clinochrysotile in nature was studied. The result shows that this technique is more effective than transmission electron microscope (TEM) in the study of inner diameter of clinochrysotile nanotubes. It has the following merits: (1) it can be applied to a lot of samples; (2) the information of size, distribution and variation of the inner diameter of ringent nanotubes can be acquired; (3) according to the N_2 adsorption and desorption processess of ringent nanotubes, the special physical and chemical characteristics can be thoroughly studied; (4)combining with the other methods, we can obtain more information and parameters, such as the outer diameter.
