摘要： 高分子物理课程中的哲学内容非常丰富，本文着重介绍课程中有关逆向思维的问题。例如，将高分子链的凝聚过程看成为溶解过程的反过程；为了制备出高聚物的宏观单晶体，先让单体结晶再引发单体聚合，而不是直接由高聚物来结晶；从黏度出发转向从自由体积出发来理解高聚物的玻璃化转变等三个实例。本文分享作者在教学中，助力学生运用逆向思维深刻理解高分子凝聚态和分子运动的几个基本问题。

Abstract: The course of polymer physics is rich in philosophical content, and this paper highlights the use of reverse thinking to tackle complex issues. For example, viewing the aggregation process of polymer chains as the reverse of dissolution, preparing macroscopic polymer single crystal by crystallizing monomers before initiating polymerization, rather than crystallizing polymers directly, and shifting from free volume approaches to understand the glass transition in polymers are discussed. This article shares insights from teaching experiences that help students deeply understand the fundamentals of polymer condensed states and molecular motions through reverse thinking.

Key words: Reverse thinking, Philosophical thinking, Polymer physics, Course ideological and political education
