中文摘要：

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．

英文摘要：

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.
