2) interval elimination rule
区间删除准则
3) interval oscillation criteria
区间振动准则
1.
By using averaging functions and a generalized Riccati transformation, new interval oscillation criteria for the differential equations are established, which are different from the most known ones in the sense that they are based on the information only on a sequence of subintervals of [t0,∞), rather than on the whole half-line.
本文研究一类具有阻尼项的二阶非线性微分方程,利用平均函数和一个广义Riccati变换,得到了该方程的新的区间振动准则,这些准则不同于已知的依赖于整个区间[t0,∞)的性质的结果,而是仅依赖于区间[t0,∞)的子区间列的性质。
2.
By using the Riccati technique and the variational principle,new interval oscillation criteria are established for forced second-order nonlinear differential equations with damping.
利用Riccati技巧和变分原理,对带阻尼项的二阶强迫非线性微分方程建立了新的区间振动准则,推广和改进了已有的一些结果。
4) attribute inteval recognition criterion
属性区间识别准则
5) Domain criteria

相间准则
1.
By applying the judging criteria of alternate and characteristic points to search the gradient of enveloping line,the new algorithm sets up automatically a constraint zone of the gradient of the envelo.
