摘　　要：现行教材中对于熵弹性的阐述离不开Boltzmann熵公式。本文重点就微观状态数这一概念,从知识的连贯性、一致性出发展开论述,进一步强调了高分子物理和物理化学间的联系以及针对高分子应用物理化学结论时的差异性。以自由连接链为例对引入构象数与几率密度代替Boltzmann熵公式中的微观状态数的合理性和必要性进行了详尽讨论。能够帮助学生更系统地理解本专业知识,实现知识体系的“自洽”。The exposition of entropy elasticity in the current textbook is inseparable from the Boltzmann entropy formula.Focused on the concept of microscopic state numbers,further emphasizing the connection between polymer physics and physical chemistry and the differences in physicochemical conclusions for polymer applications,the rationality and necessity of introducing conformational numbers instead of the microscopic state numbers in Boltzmann s entropy formula were discussed in detail,highlighting the significance of interdisciplinary in teaching.It can help students understand professional knowledge more systematically,and realize the“self-consistency”of the knowledge system.
