本文对具功能反应的食饵-捕食系统进行定性分析,讨论了系统x=x(a-bx^n)-kx^βy,y=y(-d+ekx^β)在α≥β〉0的参数条件下平衡点的性态,极限环的存在性。不存在性与唯一性.
This paper deals with a kind of food-predator system with parameter:x = x(a - bx^a) - ka^βy, y = y(-d +ekx^β) . The properties of equilibrium, the existence, non-existence and uniqueness of a limit cycle in the condition of α≥β〉0 are obtained.
