摘要
简单介绍了投影的概念、分类、性质和三面投影体系的建立等投影知识。运用正投影法将立体晶胞转变成平面投影;借助湖南省2022年普通高中学业水平选择性考试化学试题第18题的第4小题探讨怎样把平面投影还原为立体晶胞。同时,对该试题的设计提出了自己的看法。
The concept,classification,properties of projection and the establishment of three-plane projection system are briefly introduced.Use the orthographic projection method to convert the three-dimensional unit cell into a plane projection;With the help of the fourth subquestion of the 18th question of the 2022 Hunan Provincial General High School Academic Level Selective Examination,this paper discusses how to restore the plane projection to a three-dimensional unit cell.At the same time,the authors put forward their own opinions on the design of the test questions.
