摘　　要：本文对比分析了研究晶体宏观形貌与内部结构关系的3种主要理论,即布拉维法则、周期键链理论和负离子配位多面体生长基元理论。提出利用布拉维法则,结合晶胞形状及结构中螺旋轴、滑移面的影响,可以更准确地分析晶体的习性,并据此对晶体习性进行了分类。Three theories about the relationship between crystal structure and form, Bravais rule, periodic bond chain (PBC), and the theory of growth basic-structural unit of negative ion coordinating polyhedron, were balanced and analyzed in this paper. The results indicate that using Bravais rule, combining with the effect of the form of crystal cell and the screw axis and the slippage face in structure, the crystal behaviour can be more accurately analyzed. On these grounds the crystal behaviours were classified.
