摘　　要：用不同工艺条件将γ-HNIW转晶为ε-HNIW,得到不同晶癖的ε-HNIW;采用不同包覆剂对ε-HNIW进行包覆研究,得到了表面改性的ε-HNIW;对两类样品进行了机械撞击感度研究。结果表明,近似平行四边形、颗粒较均匀、碎晶少的样品感度最低;颗粒细小、细针状、碎晶多的HNIW样品感度高;石蜡、丁腈橡胶可良好钝感HNIW,聚碳酸酯、丙烯腈-丁二烯-苯乙烯共聚物包覆的样品的感度较高。The ε-HNIW crystals with various crystal habits and modified ε-HNIW coated with several kinds of coating materials were obtained under different technological conditions and their impact sensitivity were determined. The results show that ε-HNIW crystals with approximate parallelogram shape and identical size have lower impact sensitivity and little needle ε-HNIW crystals have the highest impact sensitivity among these samples. Wax and butadiene nitrile rubber can effectively decrease the impact sensitivity of ε-HNIW, whereas polycarbonate、 acrylonitrile-butadiene-styrene can not.
