摘要
目的对一类具功能反应的食饵-捕食系统在参数变化下作定性分析。方法常微分方程定性与稳定性理论。结果得到此类生物捕食系统在参数变化下的平衡点的性态,及极限环的存在性,不存在性与惟一性的条件。结论补充和完善了前人的结果。
Aim To study the qualitative analysis of a kind of food-predator system with parameter. Methods Using qualitative and stability theory of Differential Equations. Results The quality of the equilibrium is discussed, the conditions of existence and uniqueness of the limit cycle in this system are obtained. Conclusion The conclusion is renewed.
