摘要：

A simple method for the discrimination of surface fractality is proposed. This method is based on the comparison of the nitrogen adsorption isotherm on a given sample with the “standard” isotherm on a smooth surface. The proposed comparative method makes it possible to determine the lower limit of the scale range of surface fractality. A thermodynamic method is recommended as a complement to fractal analysis in the scale range of about 10-1000 Å. The results of the investigation of surface roughness are presented with examples of typical samples of silica gels, porous glasses, apatite, and coal. © 1993 Academic Press, Inc.
