摘要: 在实验上用实时观察法和Kyropoulos技术生长水杨酸苯脂单晶,研究晶体形貌随过冷度的变化关系。在理论上采用Hartman-Perdok的PBC方法,分析水杨酸苯脂单晶形貌和晶体结构的关系。应用木原的核心势能模型,扩展了PBC理论。解析的晶体形貌与实时观察法得到的晶体形貌相当一致。
Abstract: The morphological change of salol crystals with respect to supercooling is studied by in situ observation method and the Kyropoulos technique. The relation between morphology and structure of salol crystals is analysed based on Hartman-Perdok's concept of periodic bond chains (PBC). Kihara's core potential model is used to extend PBC concept. The theoretical morphology derived by extended PBC method gives better fitting to observed morphology obtained by in situ observation method.
