用线的分形生成解释了分形和分维数的基本概念。导出了粉碎粒度分布的分维数和分裂比、粉碎概率互相间存在的简单关系。从测定颗粒表面的分形构造出发，给出了粉碎能耗和粒度分维次方成反比的结果。
Fractal generation with lines explains the basic concepts of fractal and fractal dimensions. The simple relationship between the fractal dimension and the splitting ratio and the smashing probability are derived. Starting from determining the fractal structure of the particle surface, the results show that the comminution energy consumption is inversely proportional to the fractal dimensionality of particle size.
