摘要
研究了生物化学反应中一类非线性系统 .得到了该系统存在环绕正奇点极限环的充分必要条件 ,并且证明了如果存在极限环 。
A nonlinear system in biochemical reactions is considered.The necessary and sufficient conditions for the system has the limit cycles surrounding the positive singular point are obtained.And it is proved that if there exist the limit cycles,then the uniqueness of the limit cycles follows.$$$$
