摘　　要：讨论了含引发机制的Af-Ag型缩聚反应体系,利用该体系数量分布函数,给出了高分子矩的循环公式.进一步应用循环公式,计算了1次、2次、3次高分子矩,进而得到凝胶点前后的数均分子量、重均分子量和Z-均分子量的明确表达式.By means of the number fraction distribution for the Af-Ag type condensation involving initiation step, the recursion formula of the polymer moment was deduced. Furthermore, the first, second, third polymer moments and number average molecular weight, weight average molecular weight, Z-average molecular weight for pre-gel and post-gel were obtained by means of the recursion formula and the invariant property of average polymer physical quantifies.
