摘要
通过利用Riccati变换和Philos方法,获得了具连续分布时滞和阻尼项的二阶半线性中立型泛函微分方程的区间振动准则,推广和改进了文献中的结果.
By using Riccati transformation and Philos＇ s method, some new interval oscllatory criteria for second order half-linear differential equations with continuous distributed delays and damping terms are ob- tained. Some previous results are generalized.
