摘　　要：根据一种中孔硅胶对亚甲基蓝、结晶紫、番红花红T、酸性红94和甲酚红等五种染料的吸附数据结果计算了该硅胶表面分形值D。由吸附数据得出的该硅胶表面的分形值D等于2.002。利用平衡吸附量nm取代极限吸附量nl,求得硅胶表面分形值D,计算过程更加简明。The degree of the surface fractal of silica gel is measured by adsorption of methylene blue（MB）, crystal violet, Safranin-T, acid red-94 and cresol red.The result of the degree is about 2.002.Adsorption capacity of equilibrium is substituted for that of limit, so the calculating process is simple and clear.
