摘要： 给出二阶系统的振动条件.作者拟从非线性系统(2)的振动条件着手,进一步研究具有偏差变元的非线性系统(3)的振动条件,改进了国内外一些已发表的结果.

关键词: 条件, 非线性振动, 矛盾, 泛函微分方程

Abstract: This paper will give conditions of second order system oscillation. We will make a farther study on the conditions of the oscillation of the non-linear system (3) having deviation variable on the basis of that of system (2) which improves some of the results having published at home and abroad.

Key words: non-linear oscillation, functional differential equation, conditions, contradiction
