摘　　要：运用分形理论推导出了强度与缺陷分布分数维之间的关系，建立了粉碎颗粒粒度分布模型，找出了分数维、分布指数与破碎概率之间的关系，用颗粒表面分数维Ｄｓ将３种功耗理论统一起来。The relation between strength and fractional dimension of defect distribution is derived using fractal theory; a size distribution model for pulserized particles is established; the relation between fractional dimension, distribution exponent and crushing probability is found. Three power consumption theories are united using the fractional dimension, of D s  of particle surfaces.
