摘　　要：研究了带有相互干扰与Beddington-De Angelies功能反应函数的时滞多种群脉冲系统,并通过运用叠合度理论研究了系统周期解的存在性。A study is made on time - delayed impulse system of multi - species model with mutual interference and Beddington - DeAngelies functional response. By applying the continuation theorem of coincidence degree theory, some sufficient conditions for the existence of positive periodic solutions of the system are obtained.

关 键 词：相互干扰 Beddington-DeAngelies功能反应函数 脉冲 周期解
