摘　　要：微观对称性是晶体结构教学的重要内容之一,是点对称要素和平移对称要素的组合,称为空间群。本文采用Diamond软件构建Pm3m、Fm3m、Fd3m和F43m等四种立方晶系常见空间群的晶体结构模型,分析了空间群符号中各字母和数字所表达的含义,并展示了对称要素和对称操作。以直观的形式将抽象的内容具体化,有利于学生更好的理解和掌握空间群的概念,增强教学效果。The microscopic symmetry ofcrystal structure is one of the important contents of crystallography.It is a combination of point symmetry elements and translation symmetry elements,called space groups.Diamond software was used to construct the crystal structure models of four common space groups of cubic crystal systems,such as Pm3m,Fm3m,Fd3m and F43m,and the meanings of the letters and numbers in the space group symbols were analyzed,the symmetry elements and symmetry operations was alsoshowed.Concretizing the abstract content in an intuitive form will help students better understand and master the concept of space groups and enhance the teaching effect.
