摘　　要：研究了带有时滞的非线性离散系统,借助差分方程理论,通过比较定理和极限理论,获得了保证该系统永久持续生存的充分性条件。最后,举例说明了结果的可行性。A nonlinear discrete system with delays is studied.With the help of the theorem of differential equation,by applying comparison theorem and limit theory,some sufficient conditions which guarantee the permanence of the system are obtained.Finally,an example has been given to show that our main results are verifiable.

关 键 词：时滞 非线性 离散 持久性
