摘要
本文研究了非线性微分方程 L_(nX)(t)+p(t)f(x[h(t)])=0(n 是偶数)关于f(·)和 p(·)满足一定的条件时,几个方程的解具有振荡性的充分条件。
The oscillatory solutions of even order nonlinear differentialequations L_nx(t)+p(t)f(x[h(t)])=0(n is even order)are considered inthis paper.As f(·) and p(·)satisfy specified conditions,it is obtainedthat the solutions of the equations are oscillating.
