摘要：

The surface fractal dimension, d(fs), is a parameter for the characterization of the surface roughness which is independent of the size of the scale applied on the sample surface. By means of a thermodynamic method d(fs) as well as the limits of fractality can be obtained from the nitrogen adsorption isotherm at 77 K in the region of capillary condensation. The applicability of this method is demonstrated on several disperse materials of different origin.
