Shape is software flexibly to deal with crystal structure. The process and skill to deduce the single form in crystallochemistry are introduced combining with the practices in teaching. Two examples were applied to show the process to deduce singe form. Shape software makes the teaching process more attractive and efficient than that of traditional one. Students deeply comprehend key points such as symmetrical elements, the combination of symmetrical elements and single forms, which have higher efficiencies.%Shape是一款可灵活处理晶体结构的软件.结合教学实践,介绍了Shape V7.1在结晶化学中单形推导方面的使用过程及技巧.文中列举了对称型L22P和对称型3L44L36L29PC晶类推导单形实例,以演示此过程.通过Shape软件的使用使传统教学过程更有吸引力、更有效,使学生在实习过程中,能够更好地理解对称要素、对称要素的组合规律、各单形的推导等,有效提高学习效率.
