摘要
以平均Ｌｉａｐｕｎｏｖ函数方法为基础，对一般的有限时滞离散种群模型建立了一致持续生存条件．并将结果应用于一个增长函数分别为指数和分式形式的带时滞的两种群竞争模型。
Conditions of permanence for general discrete models with finite delays are established via the average Liapunov function method.The results are applied to both a 2 species delayed competition model (where the growth functions are exponential and rational respectively) and the n species Lotka Volterra model with delay.
