在构象异构的教学活动中我们发现,教师对纽曼(Melvin S.Newman)投影式含义的理解存在歧异,于是我们带着这个问题做了一点考证。大凡基础的有机化学教科书,在介绍构象概念之后,一般均介绍了构象式的画法。构象的书面表示法,概括起来有三种:一是球棍式,二是萨哈斯(Sawhorse)投影 In the conformational heterogeneous teaching we find that teachers have different understanding of the projection of Newman’s (Melvin S.Newman), so we do some research with this question. Basically based organic chemistry textbooks, introducing conformational concepts, are generally introduced conformational painting method. Conformation of the written representation, summed up in three ways: First, club-style, the second is Sahasz (Sawhorse) projection
