摘　　要：本文比较了一维势箱中的粒子模型和休克尔分子轨道理论两个教学过程的不同;分别用两个理论处理了链状共轭分子辛四烯、环状共轭分子苯的结构,不同的理论得到的结果有所不同.通过教学中前后联系、对比教学来解决结构化学教学过程中化学模型多,理论假设多,同学容易混淆的难题.This paper compared the two teaching processes of the particle model in one-dimensional box and Hückel Molecular orbit method theory. These two theories are used to deal with the structures of the chain conjugated molecule octadiene and ring conjugated molecule benzene,and the results are different. In the teaching process,the methods of relating context and comparison are always used to solve the problems of too much chemical models and theory hypothesis.
