平稳的

According to the characteristic of statistics, time series is divided into two classes.

时间序列分析按时间序列的统计特性可以分为平稳时间序列和非平稳时间序列两类。

An approximation method of queueing networks in series with exponential servers with buffers, Poisson arrivals and block ing is presented.

本文讨论产品以Poisson过程到达，有K道加工工序，每加工点是有限容量且服务服从指数分布带受阻的排队网络，并给出了平稳条件和在平稳条件下以三节点组合逼近方法得到平均队长。

The non-stationary index of automobiles\' supporting force response under side wind is analyzed, which confirms the reasonableness of stationary assumption in dynamic reliability analysis.Thirdly, joint distribution of wind speed and wind direction is established based on the extensive extreme value distribution, which is used for reliability analysis of bridge traffic safety.

其次提供了Fourier变换识别抖振响应频谱失真的实例，采用Hilbert-Huang变换分析桥梁抖振响应的时频特性，从结构动力学角度探讨了响应非平稳性的原因，从风工程的角度探讨HHT变换分量的物理意义，并分析侧风作用下桥上汽车支撑力响应的非平稳指标，为动力可靠度分析中平稳性假定的合理性提供必要的论证。

Do that, no doubt, to look important – to show the world how smooth run their RollsRoyces and their Hispano Suizas. Inside me things were running smoother than any RollsRoyce ever ran. It was just like velvet inside.

毫无疑问，这样是要显得有身价，叫世人看看她们的罗尔斯一罗伊斯和希斯帕诺·苏扎斯高级轿车跑得多么平稳，而我心里却比任何一辆罗尔斯-罗伊斯更加平稳舒服，像天鹅绒一样平滑。

Do that, no doubt, to look important – to show the world how smooth run their Rolls Royces and their Hispano Suizas. Inside me things were running smoother than any Rolls Royce ever ran. It was just like velvet inside.

毫无疑问，这样是要显得有身价，叫世人看看她们的罗尔斯一罗伊斯和希斯帕诺·苏扎斯高级轿车跑得多么平稳，而我心里却比任何一辆罗尔斯-罗伊斯更加平稳舒服，像天鹅绒一样平滑。

Methods The definition of stationary random processes and joinly stationarity and the method of mathematics induction are used.

方法利用了平稳随机过程和联合平稳性的定义及数学归纳法。

But we discover that, those most important technical indicators are all stationary processes or their functional transformations. However, stationary process can be computed the frequency is well known.

我们发现，那些最重要的技术指标都是平稳过程或其函数变换，而平稳过程可以统计其频率是已有的结论。

Through ARIMA model and standardization, the non-stationary vibration series acquired in the field were transformed to stationary time series normally distributed.

将现场测得的非平稳振动序列通过ARIMA模型和标准化处理，转化成标准正态平稳时间序列。

This novel method is applicable to instantaneous or convolutive mixture models with stationary or non-stationary input signals.

此方法不仅适用于平稳或非平稳信号，而且还可用于瞬时或卷积混和模型的盲源分离问题。

Fagaceae and Theaceae are the dominant families, with the RBA value being 60.1% and 12.2%, respectively. The Shannon Wiener index of the tree layer is about 3.0. The indicies of H ′ and Pielou evenness index both increased with sampling area, and stabilized at 1500 m 2 and 1000 m 2, respectively.

多样性分析结果表明，乔木层Shannon-Wie-ner指数为3.0左右；随着取样面积的增加，H'值和均匀度指数逐渐增加；1500 m2时H'趋于平稳，1000m2时E趋于平稳。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
