摘　　要：本文讨论了晶体表面结构和负离子配位多面体结晶方位的关系。指出了晶体表面结构 ,显示了负离子配位多面体在晶体生长过程中的结晶轨迹。因此 ,运用负离子配位多面体生长基元理论模型 ,晶体的生长机制可以通过对晶体表面结构的分析得以解释。The relationship between the crystallographic orientation of anionic coordination polyhedra and the surface structures was discussed in this paper. It is suggested that the surface structures show the locus formed by the combination of growth units of anionic coordination polyhedra on different surfaces during crystal growth. Therefore the growth mechanism could be studied and the crystal orientation determined by means of the surface structures in crystals.
