摘要
研究非自治系统Rayleigh方程解的终归有界性、调和解的存在性.利用其等价的平面系统和对应自治系统的平面系统一些条件,构造一条简单闭曲线,从而由Brouwer不动点原理得出结论.
The eventual boundeness and existence of harmonic solution of Rayleigh equation on nonautonomous systems are studied.With the utilization of some conditions according to the plane autonomous system,one simple close curve is formed and,therefore,the result is obtained from Brouwer′s fixed point theory.
