论述了物料粉碎过程的分形结构、裂纹扩展的分形效应、颗粒表面的分形特征和物料粉碎能耗的分形特征等几种简单分形以及物料断面剖线和等值线的多度域分形。
The fractal structure, the fractal effect of crack propagation, the fractal characteristics of particle surface and the fractal characteristics of material crushing energy consumption are discussed. The multifractal fractal of profile and contours of material cross section is also discussed.
