As for the sources of economic disparity, our models partially validated the human capital theory because educational qualifications were significant variables, in fact the most significant variables in determining an individual's chance of accessing the salariat class and avoiding being found in the non-skilled and unemployed category.

九十年代中的资料显示，在港潮籍移民在劳工市场的成就平均最为理想，相反福建移民的平均职业成就最为不理想，上海及四邑的移民则最常创业。

Correlation analysis showed that meteorological variables, such as containing water rate of sandland, photosynthetic available radiation, air temperature, saturated water vapour pressure difference, and physiological variables, such as leaf area index, leaf temperature, stomatal conductance, affected transpiration of S.

相关分析结果表明，环境因子，如沙地含水率、太阳有效辐射、大气温度和饱和水汽压差，以及植物因素，如叶面积指数、叶片温度和气孔导度等，均能显著影响沙柳的蒸腾作用。

In its empirical analysis, uses χ^2-test, analysis of variance and t-test, find out the primary variables for financial goods. Findings, the primary variables for people know and manage money matters the tool are to the stock, bond, savings, insurance, find and assembled money.

实证分析上，利用统计科学方法之卡方检定(χ^2-test)、单因子变异数分析、成对样本t-test，找出本国居民对金融商品认知之显著变数。

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。

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。

Without such detailed information, raking comes as a rescue since it requires only the knowledge of marginal distributions of selected variables. Popular as it may be, raking takes no account of associations among post-stratifying variables. Furthermore, it relies heavily on Chi-squared tests and a pre-selected p-value (usually 0.5) as the stopping rule of iteration, an ad hoc rule justified only by convenience.

因此，目前最常采用的是「反覆多重加权」的方式，但「反覆多重加权」实际执行时，最大的问题在於其检定方式是透过卡方检定，通常只要其检定P值大於0.5，就认定样本与母群一致，而未考虑一个最佳化的加权值。

By restricting the covariance structure, some theorems of the complete convergence and strong law of large numbers for PA random variables sequences are obtained by applying the properties and inequalities of PA random variables.

在这里通过对协方差结构的限制，应用关于PA随机变量序列的性质、不等式，建立了PA随机变量序列的完全收敛定理和强大数定律。

According to the combination of symbolic execution and program analysis,the collection of generated constraint and the mapping between the test case variables and the SUT variables,testing model is generated,and then model verification and test case generation are done.

采用符号执行和程序分析相结合的方法，收集生成的约束、测试脚本变量与被测系统变量之间的映射关系，据此生成测试模型，进一步进行模型验证和测试生成。

In this paper, 4 variables of the distal tarsometatarsus were also collected from 25 specimens of fossil birds belonging to 14 genera of Early Cretaceous birds from Western Liaoning in China. Analyses of these variables have also proven to be useful in distinguishing arboreal and terrestrial birds, and the result is generally consistent with a conclusion reached on the basis of other analysis, i.e. those based on the claw geometry and toe proportion.

通过对在中国已发现的25例中生代鸟类跗跖骨远端4个变量的统计分析，表明它们同样具有区别树栖和地栖鸟类的显著意义，而且分析的结果与参考鸟类其他特征（如爪的形态、脚趾的比例等）所得出的结论基本一致。

The system can be widely used in belt weighing and batching process control,etc.

介绍了基于智能模糊控制的嵌入式配料系统的设计方法，对模糊PID控制过程和系统调零作了重点的讨论，同时给出了PID控制的程序流程图和系统定长调零子程序。

"I dunno," she answered,"but if you show me aroun', I'll recognize it from the lighthouse just outside the porthole."

"我不知道，"她回答说，"如果你能带我转转，我能认出来的，因为灯塔就在舷窗外。"
