| 摘 要： | 主要研究了具有时滞的2-种群竞争年龄结构模型的周期解,利用叠合度理论的连续定理,得到了正周期解存在性的判别准则.所得结果可以采取同样的方法推广到具有时滞的n-种群竞争年龄结构模型.

| Abstract: | This paper studied a two-species delayed stage-structured competitive model.By the continuation theorem of coincidence degree theory,a set of easily verifiable criteria are derived for the existence of the positive periodic solution.The results here can be generalized to an n-species stage-structured competitive model with delays. |

| Keywords: | periodic solution stage-structure competitive system delay coincidence degree |
