摘要
Abstract
Fractal dimension (D) can be used to characterize the surface structure of porous solids. Different fractal dimensions correspond to the different micropore distributions. The relationship between the D and the micropore structure is derived. The influences of pressure on the fractal dimension and the structure of micropore are discussed in details. With the increase of the pressure, the micropores become smaller; the pore distribution becomes wider; the surface becomes coarser and the D increases up to a constant value. By using the fractal dimension, the characterization of the surface structure of porous solids becomes simple.关键词
