中文摘要：

本文研究一类带扩散的聚合物模型,并在参数γ〉0和γ〈0两种不同情形给出定性分析.主要运用抛物型方程比较原理和相应常微分方程的结论得到反应扩散方程的先验估计和渐近性分析.

英文摘要：

In this paper,we consider a reaction-diffusion system which appears in a polymerization reaction model. We obtain some priori estimates such as the boundedness and asymptotic properties of solution in different cases.
