体内毒素浓度不相同的三维时变Volterra系统的持续生存

Persistence for the Unequal Concentration of Toxicant in the Organism Volterra Time-Varying of Three Species

在环境容量很大且被污染的情形下,对体内毒素浓度不相同的三种群时变Volterra系统进行了研究,并给出了三维时变Volterra捕食系统弱平均持续生存与灭绝的条件.

This paper studies a unequal concentration of toxicant in the organism Volterra lime-varying of three species in large capacity polluted enviroment. The sufficient conditions of persistence and extinction for each population have been obtained.
