中文摘要：

利用Riccati变换技术研究了一类偶数阶中立型系数振动的混合非线性时滞微分方程的振动性,得到了该类方程所有有界解振动或者收敛于0的几个新的充分条件.

英文摘要：

By means of Riccati transformation technique,this paper establishes some new criteria which guarantee all bounded solutions either oscillate or converge to zero for a class of even order neutral differential equation with mixed nonlinearities and oscillating coefficient.
