摘要
利用Ｆｏｕｒｉｅｒ级数理论研究Ｎ阶常系数线性中立型方程的周期解问题．得到了保证周期解存在。
Study the forced vibrations of the N order linear neutral differential equations with real constant coefficients,necessary and sufficient conditions of the existence and uniqueness of periodic solutions for the equations are obtained by using the theory of Fourier series.Some brief and practical criteria are given.
