摘要
本文研究高阶常系数线性多时滞中立型方程的周期解，得到了周期解存在的充分 必要条件，改进或推广了文［１－７］的主要结果。
In this paper f periodic solutions of higher order linear neutral equations with constant coefficients and delays are studied. Some sufficient and necessary conditions of existence of periodic solutions of the equations are obtained. Main results in paper [1-7] are improved and extended.
