| 摘 要： | 通过模拟计算与试验相结合的方法,研究了添加剂乙酰胺、丙烯酰胺、乙胺水溶液对重结晶HMX晶体形貌控制的影响.结果表明,3种添加剂对HMX重结晶晶体形貌影响的大小顺序为:乙酰胺＞丙烯酰胺＞乙胺,乙酰胺使晶体偏离球形化,丙烯酰胺具有使晶体向着球形化发展的趋势,由于乙胺与HMX晶面的附着能较小,乙胺对HMX重结晶晶体形貌改变不...

| Abstract: | The influences of additives(acetamide,acrylamide and ethylamine) on HMX crystal morphology were studied by theoretical computation and experiment methods.The results show that the sequence of additives influences on HMX crystal morphology was: acetamide> acrylamide> ethylamine.Acetamide had negative influence on HMX crystal morphology and made HMX crystal morphology change in non-spherical direction,and acrylamide had active influence on HMX crystal morphology.Due to the attachment energy of ethylamine to H... |
