我们考虑Liénard类型的二阶微分方程：这类方程已经得到了非常广泛的研究，并且在应用中经常出现。关于周期解的存在性和唯一性有大量的文献：Staude[6]的论文是一个全面的综述。我们感兴趣的是这类方程的周期解的数目。
We consider second order differential equations of Liénard type: Such equations have been very widely studied and arise frequently in applications. There is an extensive literature relating to the existence and uniqueness of periodic solutions: the paper of Staude[6] is a comprehensive survey. Our interest is in the number of periodic solutions of such equations.
