【摘要】 通过研究一类具有常数投放率的食饵-捕食系统的定性行为,得到了正平衡点的全局渐近稳定以及在正平衡点周围存在唯一稳定极限环的充分条件,并用数值模拟验证了结论的正确性.更多还原

【Abstract】 Qualitative behavior for predator-prey system with constant rate stocking by function effect is discussed.The sufficient conditions for the global asymptotic stability of the positive equilibrium and the existence uniqueness of the limit cycle around the positive equilibrium are obtained.The results were proved by the technology of numerical simulation.更多还原
