一类多分子反应模型的极限环的研究

THE LIMIT CYCLE OF A MULTIMOLECULES MODEL

本文研究了一类多分子反应模型：主要结果是：存在闭轨,当，Ρ/α-1＜a＜a时，(E)有传稳定的极限环,其中本文部分结果优于文〔2，3〕．

In this paper,the authors studied a mulgimolecules model:(a＞0,p≥1,q≥2)(E)The authors obtained the following result:There exists an a＜a≤ao,such that if a＜(x,y) ∈ G or a＞a_o then(E) has no close orbit；if＜a≤a,then(E)has stable limit cycle. where Some reslults in this paper are better than those in article〔2.3〕.
