【摘要】 分析了射流撞击粉碎法制备超细炸药颗粒的原理。得出在射流撞击过程中，颗粒之间冲击压力是引起颗粒粉碎的主要原因，冲击波的作用加强了颗粒的粉碎。利用此方法制备出了亚微米级超细ＨＭＸ和ＲＤＸ高能炸药颗粒。更多还原

【Abstract】 In this paper the principle of impinging crushing method for the preparation of ultra fine particles of explosive is analyzed.The conclusion is that in the process of jet impinging crushing,the major factor of the particle’s crushing is the high speed impact among the particles.The effect of shock wave enhanced the crushing of particles.Then the sub micron ultra fine particles of HMX and RDX is obtained.更多还原
