摘要
本文利用 Poincaré- Bendixson定理和 Dulac准则研究了一类死亡率为 q(x)的较为一般的相互干扰的捕食——被捕食系统的正平衡点的全局稳定性 .
In this papers we study the global stability of the positive equilibrium of the predator-prey system with general death rate q(x) which the two populations perturb with each other by the theory of Poincaré-Bendixson and the Dulac criterion.
