摘　　要：X射线衍射和倒易点阵概念抽象,是学习的难点,X射线衍射分析的理论基础是倒易点阵,倒易点阵构建的基础是X射线衍射,两者互为基础.然而,大部分教科书中X射线衍射和倒易点阵都是分开讲解,更是给学习理解带来了困难,本文系统介绍了X射线衍射原理,并基于X射线衍射引出倒易点阵,将X射线衍射和倒易点阵统一讲解,使学习理解更加容易.concepts of X-ray diffraction and reciprocal lattice are difficult to learn.The theoretical basis of X-ray diffraction analysis is reciprocal lattice,and the construction of reciprocal lattice is based on X-ray diffraction.The two concepts are based on each other.However,X-ray diffraction and reciprocal lattice are explained separately in most textbooks,which brings difficulties for learning and understanding.In this paper,the principle of X-ray diffraction is introduced systematically.Then the reciprocal lattice based on X-ray diffraction,X-ray diffraction and reciprocal lattice are explained in a unified way in order to make learning and understanding easier.
