一类二阶泛函微分方程振动解的性质

Properties of Oscillating Solution for the Second Order Functional Differential Equations

讨论了方程ｘ″（ｔ）＋ｐ（ｔ）ｆ（ｘ（ｇ（ｔ））＝ｒ（ｔ）振动解的渐近性和有界性，利用分离强迫项的方法，获得了几个新的结果．

We discussed the asymptotic behavior and boundedness of the oscillatory solutions for the equation x′′(t)+p(t)f(x(g(t)))=r(t) in this paper.Several new results are obtained by the method of separating the forcing item.
