球状药包 meaning in Chinese

spheric cartridge

On the basis of modern blasting theories , the moving process of explosive stress field of multi - row and simultaneity is analyzed and the characteristics of stress field inspired by equivalent effect cell of globosity charge in cylindrical charge structure are considered . thus energy distributing equation of detonator explosion is established and the explosive energy utilizing rate factors are known . so the moving process model of the hole filling is constructed and the equation of calculating reasonable filling length is produced
本文在现代爆破理论的基础上，分析了多排同段爆炸应力场的作用过程以及柱状装药结构中等效单元球状药包所激发的应力场特点，建立了炸药爆炸能量分布方程，明确了影响爆炸能量利用率的因素，构建了炮孔充填物运动过程模型，得出计算合理充填长度方程。
