摘要 利用非线性问题线性化处理,讨论一类一阶非线性微分不等式振动解的零点分布,通过微分方程与相应微分不等式之间的关系,进一步对一类非线性变时滞中立型微分方程的零点距进行了估计,改进和推广了已有的一些的结果. Discuss the distribution of zeros of solution of the first order nonlinear differential inequality by linearizing nonlinear problems.Then by changing the differential equation with the related differential inequality,estimate the distance between adjacent zeros of the solutions of the nonlinear neutral differential equation with variable delays.Generalize and improve a lot of known results.
