摘　　要：研究一类具变时滞的脉冲Nicholson’s blowflies模型的概周期解,利用压缩映射原理和Gron wall-Bellman不等式,得到正概周期解存在和指数稳定的充分条件,并举例说明结果的可行性。By using the contraction mapping principle and Gronwall-Bellma’s inequality,some criteria are established for the existence and exponential stability of positive almost peri-odic solution for Nicholson’s blowflies model with impulses and delays.An example is employed to illustrate our feasible results.
