摘　　要：对炸药与金属颗粒混装及炸药与金属颗粒分装方式(添加分散剂和不添加分散剂)下炸药爆炸抛撒金属颗粒群进行了实验研究。结果表明,分装方式下颗粒容易烧结成团且在空间分布不均,添加分散剂后颗粒的分散性较好,没有烧结成团现象。混装方式下颗粒不会烧结,空间分散性较好。在有效距离内,从颗粒空间数密度、颗粒对靶板的侵彻能力、工艺和安全等方面来看,分装加分散剂方式优于其他2种方式。The dispersion of metal particles by explosive was investigated experimentally with different charge forms of explosive and metal particles： separation form（with and without dispersant） and mixture form.The results show that the particles are partly sintered and are not even distributed in the separation form without dispersant.The particles are dispersed in good-distribution and no particle is sintered in the separation form with dispersant as well as in the mixture form.Considering the number density and the penetration on target of the particles,the charging manufacturability and safety,separation form with dispersant is better than the others.
