中文摘要：

基于一系列子区间而不是整个半直线的信息,给出了一类二阶非线性阻尼微分方程的几个新的区间振动准则,所得定理推广和改进了文献和新近研究中的一些结果.

英文摘要：

Several new interval oscillation criteria for certain classes of second order nonlinear damped differential equations are presented,which are based on the information only on a sequence of subintervals of ,rather than on the whole half-line.Our results are sharper than those known in the literature and deal with the cases which are not covered by the known criteria.
