摘要
运用二维系统定性理论,研究一类二维Lotka-Volterra竞争系统在有限时间内的持续生存与绝灭问题,即β持续生存与β绝灭。
By two-dimensional system qualitative theory,this paper discusses the problem of the sustained existence and extermination of two-dimensional Lotka-Volterra competitional system in limited time,which means the problem of β sustained existence and β extermination.
