摘　　要：运用进一步发展Francisico Montes de Oca和Miguel Vivas的分析技术和微分不等式原理,得到了关于具有无限时滞和反馈控制及不含有瞬时反馈项的两种群竞争系统的持久性的充分条件。Sufficient conditions are obtained for the permanence of a two species competitive system with infinite delays and feedback controls and without dominating instantaneous negative feedback by further developing the analytical technique of Francisico Montes de Oca and Miguel Vivas and using the differential inequality theory.

关 键 词：无限时滞 竞争 反馈控制 持久性
