摘要
应用分形几何理论，研究了粉体的粒度分布特征．发现在双对数坐标下，许多材料粒径的重量累积百分含量与粒径之间呈直线关系，表明其粒度分布具有分形结构．分维可作为技度分布特征的一个序参量，它反映了粉体颗粒的粗细程度和集中、均匀特性．
The granularity distribution characteristics of powder were studied by the fractal geometry.It was found that there is a linear relationship between the accumulahve weight cotent and the grain size in log-log plot for many materials,and it shows that the granularity distribution of powder has fractal structure.the fractal dimension D may be taken as the sense-parameter,whichdescries the granularity dis-tribution characteristics of powder.It reflects degree of finess,concetration,well-distribution of fine particle.
