摘　　要：为提高超细六硝基茋HNS(HNS-Ⅳ)输出能量,采用溶剂/非溶剂法制备超细HNS/HMX混合晶体,并进行形貌表征及性能研究。结果表明:混晶中的HMX细化晶体依然为β型,并被HNS超细粒子包覆在核内;HNS-Ⅳ与超细HNS/HMX比例为80/20和70/30时,其性能测试结果为:比表面积(SBET):14.25 m2.g-1、9.98 m2.g-1、9.56 m2.g-1;撞击感度:52%、76%、78%;摩擦感度:14%、16%、19%;起爆能:0.49 J、0.50 J、0.58 J。：Solvent/nonsolvent recrystaUization method was used to prepare HNS/HMX mischcrystals in order to increase the energy output of HNS-1V ,and its structure characterization and performance were studied in detail. Results show that β-HMX is surrounded by superfined HNS particles in the core. The specific surface area,impact sensitivity, friction sensitivity,and initiaiton energy of HNS-IV, superfined HNS/HMX（80/20） and superfined HNS/HMX（70/30） are as follows： 14.25 m2·g^-1、9.98 m2·g^-1、9.56 m2·g^-1 52% ,76% ,78% ; 14% ,16% ,19% ; 0.49 J,0.50 J,0.58 J respectively.
