摘要
Kaplan J L和Yorke J A 1974年提出时滞微分系统周期解的常微分方程产生法。本文利用该法探讨了某些时滞微分方程周期解的存在性。
The method of yielding periodic solutions of differential delay equations by ordinary differential equations was proposed by Kaplan J L and Yarke J A in [1] in 1974. In this paper this method is used to discuss the existence of periodic solutions of some kinds of differential delay equations.
