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.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.
