摘要
研究一类微生物连续培养的三维竞争系统的解的结构,分析了平衡点的稳定性及平衡点附近极限环的存在惟一性,证明了该系统存在正向不变集.
The structure of solutions of a class of dimensional competition system in microbial continuous culture is studied. The stability of steady states and the existence, uniqueness of limit cycles of near equilibrium are analyzed, which proved that there exists a positive invariant set.
