该文研究了二阶中立型微分方程的振动性准则,推广了已有文献中的许多振动结果,最后给出一个例子说明结果的有效性。%New oscillation criteria for a class of second-order nonlinear neutral differential equations are obtained,which extend a number of related results in the literature and can be used in cases where known theo-rems fail to apply.An example is given to show the effectiveness.
