| 中文摘要: |
| 晶体结构的基本概念既多又抽象，没有较强的空间想象力很难理解和辨析清楚。二维图缺乏空间感；而实物模型只做出一个晶胞，其重复规律不直观。VESTA晶体结构软件能够根据需要构建多个三维晶胞，即超胞，可以很直观地显示出晶体结构的特点。本文通过几个教学实例说明VESTA软件如何帮助学生深入理解晶体结构的基本概念、结构特点与性能的关系，以及拓展晶体结构的认知领域，提高学习兴趣与探索能力。 |
| 英文摘要: |
| There are a lot of basic concepts in crystal structure. It is difficult to understand and distinguish clearly without strong spatial imagination for its abstract. The two-dimensional graph is short of stereoscopic feeling and the physical model only makes one unit cell, which cannot exhibit its repetitive pattern. VESTA crystal structure software can build three-dimensional supercells according to the needs, so it can show the characteristics of crystal structure intuitively. Through several teaching examples, this paper explains how VESTA software can help students understand the basic concept of crystal structure, the relationship between structure characteristics and performance, expand the cognitive field of crystal structure, and improve learning interest and exploration ability. |
