摘　　要：该文研究一类带有更广泛而不失物理意义阻尼项的二阶非线性中立型Emden-Fowler时滞微分方程的振动性.利用指数函数变换、Riccati变换和不等式技巧,获得了该类方程几个新的振动定理,推广、改进和丰富了已有文献中的研究结果,并逐一给出例子说明了相应定理的实用效果.In this paper,by using the methods of exponential function transformation,Riccati transformation and inequality techniques,we study the oscillation behavior for a class of second order nonlinear neutral delay Emden-Fowler differential equations with the most extensive and physically meaningful damping term.Several new oscillation theorems which extend and improve some known results in the literature recently are established and some examples are provided to illustrate the relevance of new theorems.
