摘要
对一类具功能反应的食饵-捕食者模型:.x=xg(x)-yφ(x),.y=y(-d+eφ(x))进行了研究,讨论了该系统平衡点的性态,系统无环的充分条件及正平衡点外围存在唯一稳定极限环的条件.
In this paper a class of nonlinear model:x = xg(x) -yφ(x) ,y = y( - d + eφ(x) ) is studied. The stability of equilibrium, the sufficient conditions of nonexistence and conditions of the existence and uniqueness of the limit cycle around the positive equilibrium of the system are discussed.
