摘要
本文建立了两类一阶具连续分布变偏差微分方程的所有解都振动的若干充分条件,所得结果推广并改进了现有文献中的一些结果.
In this paper is established several sufficient conditions for the oscillation of all solutions of two kinds of first order nonlinear differential equations with distributed type deviating arguments, which extend and improve some known results in the literature.
