摘　　要：相变理论和相图是高分子物理课程教学中的一个重点,但同时也是一个难点。本文对高分子物理教材中对高分子共混物的相平衡推导过程进行了补充和推广,同时提出了一种更为普适的相平衡推导方法,从教材中经典的二元简单体系出发,推广至多组分复杂体系,能够帮助学生深入理解相变理论中更为底层的逻辑关系,并为学生搭建起课程理论学习与实际研究应用之间的桥梁。Phase transition theory and phase diagrams are essential but challenging topics in polymer physics courses.This paper provides supplementary and extended derivations of phase equilibrium for polymer blends found in typical polymer physics textbooks and presents a novel method for analyzing phase equilibrium in multi-component complex systems.This approach helps students to deepen their understanding of the underlying logical relationships in phase transition theory,and to bridge the gap between theoretical knowledge in textbooks and practical research.
