摘要:

晶体结构是结构化学课程中的重要教学内容,包含的知识点多、概念抽象、理论性强。本文探讨晶体结构教学中一些基本概念的表述与内涵,包括点阵、晶格、结构基元、晶胞等,以期帮助学生澄清一些模糊不清的认识,引导学生正确理解晶体学理论的基础知识和基本概念。

关键词: 点阵, 晶格, 结构基元, 晶胞

Abstract:

Crystal structures are important teaching content in structural chemistry courses, which contains many knowledge points, abstract concepts and fundamental theories. This paper explores the descriptions and connotations of several basic concepts of crystal structures, including the lattice, crystal lattice, structural motif, and unit cell. The goal is to help students clarify their understanding of the basic concepts of crystallographic theory.

Key words: Lattice, Crystal lattice, Structural motif, Unit cell
