摘要
利用特征方程研究了辅助系统平衡点的稳定性,得到了具有阶段结构和比率依赖的捕食系统持续性的充分条件。
The stability of the equil-ibrium was studied by analyzing the associated characteristic equation. A group conditions to guarantee local stability of a two-species ratio-dependent predator-prey system with time delay and stage structure were given.
