摘要
本文介绍了利用Mathmatica软件绘制常微分方程平面自治系统相图的方法,获得了两个具有极限环的自治系统的相图,直观表明了这些系统的变化规律,它们是对理论分析方法的补充。
It is studied drawing path curve graphs by using Mathmatca software. Two path curve graphs of Autonomous Systerm with a limit cycle are obtained in this paper. The method is a supplement of qualitative analysis.
