摘要
从六硝基六氮杂异伍兹烷(CL-20,HNIW)的晶型特征、转晶方式、转晶影响因素、转晶机理等4个方面总结了其晶型转变的国内外研究进展。指出影响CL-20转晶的因素主要有溶剂、温度等;转晶的方向主要由各种晶型之间的吉布斯自由能决定;转晶机理主要通过Ostwald规则和溶液介导相变(SMPT)两个方面进行解释。指出今后转晶研究发展的重点是转晶的热动力学和抑制技术。附参考文献45篇。
The research progress of crystalline transformation of 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane（CL-20,also known as HNIW）at home and abroad was summarized from four aspects of crystal forms characteristics,transformation modes,and influencing factors and mechanism of crystalline transformation.Pointing out that the factors influencing the crystalline transformation of CL-20 were mainly solvent,temperature and so on.The direction of the crystalline transformation was mainly determined by the difference of Gibbs free energy among the various crystal forms.The explanation of the crystal transformation mechanism were performed mainly through two aspects of Ostwald rule and solution-mediated phase transformation（SMPT）.It is pointed out that the future development emphasis of the crystal transformation research are thermokinetics of crystal transformation and suppression technology of crystal transformation.With 45 references.
