The first one is about how to build the connection between describing function method and phase plane method through limit cycle analysis.

第一个是关于如何通过极限环分析建立描述函数法与相平面法之间联系；

Using the describing function method, this paper gives emphasis to analyse the conditional feedback correction effect on restrain self-sustaining oscillation.

本文利用描述函数法，重点分析了条件反馈校正对自持振荡的抑制作用。
