一类多分子反应微分方程模型的相图

THE PHASE PORTRAITS OF A BIOCHEMICAL MULTIMOLECULES MODEL

本文对一类多分子反应微分方程模型进行定性分析，在第一象限内的奇点无法具体求出的条件下，讨论了轨线的有界性，分界线的位置关系以及极限环的存在性．

In this paper,the authors give a qualitative analysis to a biochemical multimolecules model given by a differential system,under the conditions that the concrete expression of its singularities are not solved,discuss the bounded property of trajectories,separatrix configuration and existence of limit cycle.
