摘　　要：针对在讲授“高分子化学”课程有关“平衡缩聚反应”一节内容时学生出现的疑问，严格地推导了平衡缩聚方程，阐明了方程的应用范围。In view of students mistakes made in which they study 'equilibrium condensation polymerization' in 'Polymer Chemistry' course, in this paper the equilibrium condensation polymerization equation is deduced rigorously and a clear explanation of both the presupposition and the scope of application of the equation is given. Furthermore, it is emphatically pointed out that the influence of the initial functional group concentration on the average degree of polymerization in equilibrium condensation polymerization.
