本文从ＢＦＤＨ法则、ＰＢＣ理论和分子间作用力出发，探讨了极性有机晶体的理论习性及其预测，并和实际晶形进行了比较，一方面加深了对极性有机晶体生长机理的理解，另一方面则利用这一机理探讨了极性有机晶体的习性调制。根据极性有机晶体的结构特征即晶体分子具有特殊的排列方式，使得晶体沿极轴方向上的两个极性界面的结构不同，和晶体生长界面与溶剂分子的相互作用的差异，探讨了通过溶剂效应和习性调制剂来实现晶体生长的形态控制问题。
Based on the BFDH law, the PBC theory and the intermolecular force, this paper discusses the theoretical habit and prediction of polar organic crystals and compares them with the actual crystal form. On the one hand, it deepens the understanding of the growth mechanism of polar organic crystals. On the other hand, On the one hand, we use this mechanism to discuss the habitual modulation of polar organic crystals. According to the structural characteristics of polar organic crystals that crystal molecules have a special arrangement, making the crystal along the polar axis direction of the two polar interface structure is different, and crystal growth interface and the interaction between solvent molecules, discussed by the Solvent effects and habit modifiers to achieve morphological control of crystal growth.
