摘要
考虑带有非线性阻尼项的一类二阶微分方程的振动性质.在一般的假设下我们建立了这类方程的若干新的振动准则.所得结果推广和改进了文献中的某些结果.
We consider the oscillation of a class of second order differential equations with nonlinear damped ferms. Several new oscillation criteria of the equations under general assumptions are established, which develop and generalize some known results in the literature.
