Crystal chemical study of chabazite and heulandite by single crystal X-ray diffraction has been conducted to obtain important knowledge for construction of crystal chemical indication of material design for zeolite heat-absorbents in the zeolite-water heat pump system. Crystallographic configurations of water molecules and exchangeable cations in these zeolites have been determined, and the interatomic interactions, especially the hydrogen bonds between framework O atoms and water molecules, have been examined. In terms of crystal chemistry, the dehydration process of chabazite, closely related to its heat-exchange property, has been elucidated by following variation of site occupancy with dehydration.

采用单晶X射线衍射法对菱沸石和片沸石进行了晶体化学研究，为沸石-水热泵系统中沸石吸热剂材料设计的晶体化学指标的建立提供了重要依据。测定了这些沸石中水分子和可交换阳离子的晶体构型，考察了沸石中的原子间相互作用，特别是骨架氧原子与水分子间的氢键。从晶体化学的角度，通过追踪菱沸石的占位率随脱水程度的变化，阐明了菱沸石的脱水过程与其热交换性能密切相关。
