平稳

It was also observed that the rougher asperities damaged gradually by shearing and wearing in small region and the surface in contact increases with the increasing of normal stress and shear displacement.

因此，对任一条不规则的节理粗糙线，可以通过非平稳部分的正倾角或负倾角和平稳部分的平均粗糙角的结合来定量描述其表面粗糙度。

This paper introduces a recurrence formula for estimating the variances of errors of a sequence forecasted by an autoregression model and gives two examples under both smooth and nonsmooth conditions.

讨论了自回归模型的预测误差的方差估计问题，给出了详细的递推计算公式，并给出了平稳序列与非平稳序列的例子各1个。

Results During the operation, the breath and circulation in group A is more steadily than that in group B (P.05); the incidence of bodymovement and larynx spasm and the dosage of ketamine are lesser than that in group A. Postoperative children recovery is faster and more steadily in group A than those in group B.

结果 A组术中血压、心率和呼吸较接近麻醉前基础值，且术中波动较小，生命体征平稳。B组血压、心率及呼吸率均较术前明显增加，且始终保持在较高水平，随麻醉深浅而有显著波动。A组循环、呼吸功能较B组稳定(P.05)；肢体不良自主运动，喉痉挛等不良反应较B组少(P.05)；A组氯胺酮用量明显少于B组(P.01)；术后A组苏醒较快且平稳，恢复期精神症状少，与B组比较差异有统计学意义(P.05)。

And bring a new method to halt the motor calmly.

本文提出了一种新的使电机停转的方法，提出了一种新的使电机平稳停机方法，以此来达到电机平稳停机。

A new way to analysis nonstationary stochastic process is to divide it into piece-wise stationary stochastic process.

摘要将非平稳随机信号划分为分段平稳随机信号进行处理，为非平稳随机信号的研究提供的一种新的分析方法。

Previous work on this problem has typically assumed that the channel conditions between the base station and the users are governed by a stationary stochastic process.

但在实际情况中，这样的平稳假设并非总是合理的。研究表明基于平稳假设的调度算法，如流行的M-LWDF和EXP-rule算法，在非平稳信道上的性能下降明显。

In this dissertation , the methods of prediction and parameters\' estimation based on stationary multivariate autoregressive models AR(p are studied systematically. Some properties of these methods are formulized.In the first part, it introduce some basal conceptions about multidimensional stationary time series, contained the estimation and property of mean vector and auto-covariance function. Then the stable condition of multidimensional AR models are discussed.

本文主要研究了多维平稳序列自回归模型AR的参数估计及其相关的统计性质，具体内容如下：第一部分，介绍了多维平稳时间序列及其均值向量和协方差阵函数的概念，并引入了多维AR模型及其数字特征，在此基础上给出了模型的平稳性条件。

Using augmented Dickey-Fuller test, the result shows that BDI logarithm series is nonstationary but the first difference is stationary, i. e. it is integrated of order one. High-level ARCH effect was certification in the BDI logarithm series by ARCH LM test, and GARCH (1, 1) model was used to eliminate the conditional heteroscedasticity. Through variance ratio test, the result shows, that the random walk hypothesis of BDI logarithm series can be rejected and international dry bulk shipping market is inefficient.

运用ADF检验方法对BDI的对数序列进行平稳性和单整检验，结果证明BDI对数序列是一个非平稳过程，经一阶差分后是平稳过程，即BDI对数序列是一阶单整过程；通过ARCH LM检验认为BDI对数序列存在高阶ARCH效应，并用GARCH(1，1)模型消除了残差序列的条件异方差性；通过方差比检验法对国际干散货航运市场的收益率序列进行了检验，结果显示BDI的对数序列的随机游走假设被拒绝，国际干散货航运市场不是一个有效的市场。

But with last year"front Gao Hou4 Di" dissimilarity BE, 2005 investment growth more steady, do not appear "crustily six" that someone anticipate, September ratio growth most slow of February only 3.1 percentage point in Gao Chu, increase soon and more quick and steady present towards promote national economy steadily circulate develop importance function, express nation the policy effect of"have retention to press, differentiation treat" just at.

但与上年&前高后低&不同是，2005年投资增长比较平稳，并未出现有人预计的&硬着陆&，9月比增长最慢的2月份仅高出3.1个百分点，增速较快而且平稳对促进国民经济平稳运行发挥了重要作用，表明国家&有保有压，区别对待&的政策效应正在显现。

It points out the exterior impaction of export departments on non-export departments and the impactions of primary products export and industrial products export and reveals the essential characteristic of China's economic operation through the empirical results, thus analyzing the impact of export trade on China's economic growth objectively.

为了避免谬误回归的产生，本文从非平稳的实际变量来考察，将名义变量合理地转化为实际变量，然后利用ADF单位根检验各变量的平稳性，对于非平稳的实际变量，利用协整理论来分析变量之间的长期关系。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
