摘　　要：针对中学化学“物质结构与性质”模块3个版本教材中有关石英结构的二维图形不利于教学的局限性,利用“晶体学开放数据库”数据制作α-石英晶体结构三维虚拟模型,借助三维虚拟技术强大的交互功能全方位探索α-石英的空间结构,展示α-石英独特的大半径双螺旋手性结构,揭秘其旋光性的原因。教学实践表明,利用三维虚拟技术拓展中学结构教学的广度和深度是可行的。Aiming at the limitation of the two-dimensional graphs of quartz structure in the module of “material structure and properties” included in three versions of senior high school chemistry textbooks, the data from the “open database of crystallography” is used to create a three-dimensional virtual model of α-quartz crystal structure. The powerful interactive function of 3 D virtual technology makes it possible to explore the spatial structure of α-quartz in all directions, display the unique large-radius double helix chiral structure of α-quartz, and reveal the reason for its optical rotation. The teaching practice shows that it is feasible to use 3 D virtual technology to expand the breadth and depth of structure teaching in high school.
