摘要
某些固体物质的不规则表面是分形结构。根据有机物在这些物质上的吸附,可以测出分维D_f.且2【D_f【3。由于这些分维值与有机物和吸附剂的结构性质有关,因此它们在探讨吸附机理方面有重要的意义。
The heterogeneous surfaces of some solid materials (graphite, charcoal. Faujsite. etc)are fractals. The fractal dimension (D_t) mag be determined according to the adsorption of organic compounds on these materials, and the values obtained being 2<D_t<3. The fractal dimension is of great theoretical and practical importance for the study of adsorption mechanism because it depends on the structure properties of the organic compounds and adsorbent.
