变量

It means to recognize periodicity by analyzing the spectral density of periodically variable sequence, then to judge the measured period true or false through the statistical examination of Fisher's Kappa and Bartlett's Kolmogorovsmirnov.

第三节"波动周期的模型测定法"以"收入—支出"结构和"需求导向"为基本构架，通过建立中国宏观经济波动模型来测定宏观经济内生变量波动的周期长度，这种通过解析思路测定经济变量波动周期的方法，具有理论支撑，其科学性、可信性是显而易见的。

This pump configuration, which is adopted here in experiments, makes pump feature quick displacement variation and high reliability due to the direct drive of displacement variation mechanism by servo valve and reset of maximum displacement by balance spring.

液压泵的斜盘由弹簧复位到最大排量，工作中伺服阀直接驱动变量机构，有利于提高变量响应的速度和液压系统的安全性。

The standardized estimated value of latent variable score was obtained with LISREL 8.53 in this paper.

采用了基于潜变量得分的多水平多重回归模型及单变量随机系数模型，辅以图示获得了较为直观的结果。

So we can get almost starlike mappings of order α and starlike mappings of order α in several complex variables by related functions in one complex variable.

由此，我们可以利用单复变量的α次的殆星函数和α次的星形函数构造出多复变量的α次的殆星映射和α次的星形映射。

You can use the static keyword to specify that a particular element of an object is static, but Java objects themselves are never placed in static storage.

你可以使用关键字static来定义一个对象中的变量为静态变量，但是Java中的对象是不可以放在静态区域内的。

Question : So if one stat ic variable in one object changes , other statice variables in the other object will NOT be modified .

而其它变量必须要有对象存在时才存在，而且每当创建一个对象的时候就从改变量处

Secondly, we obtain the moderate deviation principles for NA random variables with stationary distribution under a weak condition, and then we give the MDP for m-dependent random variables..

其次， 我们在一比较弱的条件下得到了平稳NA随机变量列的中偏差原理，并给出了m相依随机变量列的中偏差原理。

This paper puts forward a univariate AR(1) model that relates stock price,stock returns and dividends to study stock returns autocorrelation function, and adoptsa variance decomposition to analyze variation between expected steek returns and unexpeetedstock returns.

提出一种联系股票价格、股票收益及股息的单变量回归模型来研究股票收益的自校正，并采用变量分解法探讨股票预期收益与非预期收益两者之间的变动关系。

One way is to regard them as the random variables submit to a certain distribution; another is to take them as a random process—— we derive random variables form any of its function's time development, and, the diffusion equation could be partially approached by a equation which is similar to the Ito stochastic integral equation so that the Ito stochastic integral equation is inter-related with the diffusion equation. Therefore, this process could basically reflect the uncertainty in different models.

PSFEM法是假定基本随机变量在均值点处产生微小摄动，利用Taylor级数把随机变量表示为确定部分和由摄动引起的随机部分，从而将有限元控制方程转化为一组线性的递推方程，求解得出位移的统计特性，进而求出应力的统计特性。

The result from the two methods, it is very close and good for the bridge. We also do correlation to the stochastic variable with the stress of the failure models.

同时采用数理统计的方法，分别随机变量和失效模式所对应的应力值进行相关性分析，分析随机变量对失效模式的应力值的敏感性。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
