与目前所用的判别元件相比，该元件不需要采用浮动门槛，动作灵敏度较高，不受电力系统振荡的影响，能更准确有效地判断出系统是否发生了发展性故障。

Criteria for model comparison were residual variance estimates, minus two log likelihood function, Akaike's information criterion, Bayesian information criterion, Bayesian factor, information-theoretic measure of model complexity, and percent relative reduction of complexity.

模型的统计标准有总剩余方差、似然函数对数值、Akaike信息尺度、贝叶斯信息准则、贝叶斯因子、模型复杂性尺度和复杂性相对下降率。

The Routh criterion of control system theory is applied to obtain the stability criterion.

通过对整流桥换相过程的分析，建立了系统在稳态运行点的微变稳定模型。

"Routh criterion",The Routh criterion can be used on low order systems .

"，"罗斯准则可使用在低阶系统上。

It has the same principle with the Routh criterion in substantial although their forms or patterns are different, so they are commonly called Routh-Hurwitz criterion.

尽管其形式与劳斯判据有所不同，但两者依据的原理相同，所以，我们通常称其为劳斯--赫尔维茨判据。

In the study of the stochastic chaos in simple pendulum, the random Melnikov process is derived and the mean-square criterion is used to determine the threshold amplitude of the bounded noise excitation for the onset of the chaos or random chaos in the system. For the coupled simple pendulum and harmonic oscillator, the Melnikov function is used to determine the condition for the onset of chaos in the case of Hamiltonian perturbations. In the case of non-Hamiltonian perturbation, the generalized random Melnikov process and mean-square criterion are used to determine the threshold amplitude of the bounded noise for the onset of random chaos.

在随机混沌研究中，应用随机Melnikov过程的均方准则研究了单摆在有界噪声激励下发生混沌或随机混沌时有界噪声激励的临界幅值；对于耦合的单摆-谐振子系统，先用Melnikov函数研究了在哈密顿扰动下发生混沌的必要条件；然后用推广的随机Melnikov过程方法研究了在非哈密顿扰动下发生随机混沌的必要条件；用最大Lyapunov指数及Poincaré截面方法结果与上述理论结果作了对比。

Finally, the problem of the stress release of the expansive soil roadbed slope in the excavation process and the failure criterion in the sliding simulation are discussed. The synthetic criterion for the unstable slope is proposed. The dynamic simulated analyses on the stability of the expansive soil roadbed slope in the process of digging, fore-and-after of soaking and different soaking depth have been carried out.
