摘　　要：楔形式与纽曼投影式是两种重要的构象和立体结构表达式,本文通过对学生在二者转换时存在的困难及转换方法技巧进行总结,以帮助学生实现两种表达式间的精确转换。此外,文章还介绍了一种新型的改良纽曼投影式表示法,与传统纽曼投影式相比,显示出一定的优越性。Dash-wedge diagram and Newman projection are two important conformational and stereoscopic structure expressions. This article summarizes students＇ difficulties and conversion skills in the transition process to help students achieve accurate conversions between the two expressions. In addition, the article also introduces a new type of modified Newman projection representation, which shows a certain superiority compared with the traditional one.
