摘　　要：考虑一类具有时间滞后的Lotka-Volterra竞争系统的行波解.通过构造适当的上下解,证明行波解的存在性.并指出时滞对于行波解存在性的影响.Travelling wave solutions of a class of competitive Lotka-Volterra system with time delay were considered. By constructing proper upper-lower solutions, the existence of travelling wave solutions was proved. Especially, the effect of time delay on the travelling wave solutions was taken into consideratiorL
