摘要
研究了一类一阶非线性具偏差变元的微分方程解的性质,获得了其解的有关振动性质的一些新的结果,所用的方法也适用于时超微分方程,所得结果推广了文献中的相应结果.
The poperties of oscillation for a class of first order nonlinear differential equations with deviating arguments were studied in this paper, and some new oscillatory results were obtained. This method can also be applied in advanced differential equations, and the obtained results extend the corresponding results in the literature.
