查询词典 stability criterion

For the former two types of soil, the Quincunx sampling was selected, and the random sampling used in the Qixia Temple for landform needs of mountain. The evaluation standard was based on requirements of Environmental Quality Standard for Soil（GB15618-1995）that the soils of mining area and Qixia Temple used the third criterion and vegetable garden used the second criterion.

露天采矿区和菜地土壤采用梅花布点采样方式，栖霞寺由于属于山地，采用随机布样方式；评价标准参考国家土壤环境质量标准（GB15618—1995）的要求，对矿区和栖霞寺林区土壤采用土壤环境质量三级标准进行评价，对菜地土壤采用二级标准评价。

The sensitivity of the proposed criterion is higher than that of the quondam criterion, and no floating threshold is used. It can judge the evolved fault quickly and correctly whether the power systems swing or not.

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。

"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。

Traditional ways of demarcation tends to focus on revelation of the characteristics of essential facilities that have proved far from satisfactory,among which,the criterion laid down by the court in the case of MCI seems tautological in logic;the public welfare criterion appears to transfer a vague issue into an even indefinite one;while the competitor standard ignores the integral effectiveness of the whole market;...

其中，美国"MCI"案中法院提出的标准存在逻辑上的同语反复；公共利益标准将有待澄清的问题转化为了另一个不确定的问题；竞争者标准忽略了市场的整体效果；消费者偏好标准只是对于特定情况的处理，不能成为一个基本的判断标准。核心设施界定的关键是对"不可复制性"的理解，通过借鉴相关市场界定的方法，可以确定替代发生的范围，以及替代实现的程度，从而对正确地适用核心设施理论提供新的思路。

The noise of Gold(750kW) wind power generator set can meet the requirement of the criterion of industry corporation noise control and the criterion of noise in city area , by the noise reduction measure thereinafter.

通过以上的降噪措施，金风750kW风力发电机组的噪音水平满足《工业企业噪声控制设计规范》和《城市区域环境噪声标准》的标准要求。

Fisher criterion assumes that each sample has a unimodal,symmetric distribution for each class.However,when the training sample size is large and their distributions are multimodal or skewed,the definition of classical Fisher criterion can not correctly reflect the distribution of the data in the sample space,in that case,the sets of discriminant vectors are not optimal virtually.

Fisher准则函数的前提条件就是假设每类样本数据满足单峰高斯分布，即各类样本在模式空间的分布近似椭球状，但是当训练样本数据较多且呈多峰分布时，传统的Fisher准则函数并不能准确反映样本数据的分布，显然基于Fisher准则函数的线性判别分析得到的最优判别矢量集也不是最优的。

In order to check the consistency and the maturity of models, this text describes how to upbuild a criterion and applied model in detail complied with the criterion of UML1.1 through an instance,besides this text puts forward a method of dynamic simulant test based on UML model.

为检查模型之间的一致性和模型的完备性，该文根据UML1.1规范，通过一个实例详细描述了如何建立一个规范和实用的模型，并提出了一种基于UML模型的动态模拟测试方法。

第一百四十四条香港特别行政区政府保持原在香港实行的对教育、医疗卫生、文化、艺术、康乐、体育、社会福利、社会工作等方面的民间团体机构的资助政策。原在香港各资助机构任职的人员均可根据原有制度继续受聘。

Small wonder, then, that the Chinese spend more in the shop than any other group of foreign visitors do .

这样的小惊喜，使中国顾客比任何国家的人消费得更多。
