报告摘要：The purpose of this paper is to present a sufficient condition which guarantees that an interior equilibrium of a certain predator-prey system is uniformly globally asymptotically stable.  

This ecological system is a model of Lotka-Volttera type whose prey population receives time-variation of the environment.  We assume that the time-varying coefficient is integrally positive and has a weaker property than uniformly continuous.  Our sufficient condition is expressed by an improper double integral on the time-varying coefficient.  Our work is inspired by the study of the stability theory for damped linear oscillators.
