Then I establish an almost sharp bounded oscillation and nonoscillation criterion. In the final Chapter I first obtain an almost "sharp" oscillation and nonoscillation criterion for the odd order superlinear delay differential equation with several delays.
第四章研究了偶数阶不稳定型超线性时滞微分方程解的振动性，通过构造相应不等式的解并运用Banach压缩映射原理，证明该方程总存在一个无界最终正解，继而建立了保证其所有有界解振动的几乎“sharp”的有界振动准则。
