摘　　要：研究具时滞的人口模型的行波解存在性问题.利用[5]中的方法,将行波解的存在性问题转化为 寻找上下解的问题.This paper considers traveling wave front solutions for a diffusive population models with time delays. The existence of such solutions is proved using the technique developed by J. Wu and X. Zou. Thus the existence of traveling wave front can be reduced to the existence of an admissible pair of upper solution and lower solution which are easy to construct.
