摘　　要：采用X射线粉末衍射(XRD)和差示扫描量热分析(DSC)方法,跟踪研究了N-(1-萘基)琥珀酰亚胺的液氮淬冷样品在室温(25℃)即在玻璃化转变温度以下的冷结晶行为.DSC和XRD的结果一致表明,其冷结晶动力学曲线与熔融结晶完全不同,呈现出"快-慢-快"的三阶段增长趋势,这一结果可以用低密度界面区成核和体积收缩效应给予解释.Cold crystallization process of N-（1-naphthyl） succinimide below glass transition temperature was monitored by differential scanning calorimetry （DSC） and X-ray diffraction （XRD）. The results showed that the kinetic curve of cold crystallization was completely different from that of melt crystallization, exhibiting ＂fast-slow-fast＂ three increasing stages. This result could be explained in terms of low-density-interface nucleation and volume-contraction effect.
