摘　　要：本文从动力学角度出发，引入能量因子的概念，建立了炸药破碎能耗与块度分布的关系式。该公式运用简洁、方便，不受其他块度分布方程的限制。所得计算结果与试验结果十分吻合。该结果丰富了研究爆破有效玻碎能耗及介质破碎过程的分析方法。In this paper, a new dynamic relation between the consumption of energy and distribution of particle size has been established based on the dynamic analysis.Comparedto other calculation method this equation is simple and convenient to be applied in practice. It also coincides well with the results of the experiment.
