To avoid or reduce re-analysis, we derived the augmentative matrix variation only in summation of the previous matrices time the outside-perturbed parameters by decomposing the element stiffness and mass matrix. The implicit function of amplitude about design variables such as cross-areas and lengths is changed into simplistic function about the perturbed parameters of design variables. Several methods for determining the value of perturbed parameters are detailed.

为避免或减少重分析，将有限元单元阵进行了分解变换组装，使振幅与设计变量如截面面积、长度的复杂隐函数关系转化为对设计变量摄动参数的显式关系，进而将设计变量摄动参数提取在分解后的几个常数刚度阵、质量阵之外，避免了在迭代求解过程中重组刚度阵与质量阵，较快地获得问题的解。

A virtual stochastic process is constructed so that the basic random variable becomes the value of the stochastic process at certain instants of time.

在此方法中，构造一个与基本随机变量相关的虚拟随机过程，使得基本随机变量成为该随机过程的截口随机变量。

In this paper, univariate or/and bivariate binormal model was established and its parametrers was estimated by the"method of scoring". To calculate the statistical significance of the difference between two ROC curves using any one of three distinct statistical tests: the bivariate Chi-square test, the area z-score test, and the TPR z-score test.

本文探讨了单变量、双变量双正态ROC模型的构建及其参数的最大似然估计方法；采用双变量卡方检验、真阳性率z检验、面积z检验三种方法比较了ROC曲线间是否具有显著性差异。

For fitting ROC curves and getting the area under the ROC curve, we applied the parametric methods of binormal models and ordinal regression models, the semiparametric method of Cox proportional hazards model, the nonparametric methods of Hanley, Delong This paper also include estimation of required sample size, evaluation of confounding effects, and estimation of standard error and confidence interval by resampling method for ROC analysis.

目前该模型用于ROC分析的统计学方法比较完善，属于"经典"的ROC分析参数法。本文探讨了单变量、双变量双正态ROC模型的构建及其参数的最大似然估计方法；采用双变量卡方检验、真阳性率z检验、面积z检验三种方法比较了ROC曲线间是否具有显著性差异。

A VariableReference evaluates to the value to which the variable name is bound in the set of variable bindings in the context.

变量引用的值是上下文中的变量绑定集合中变量名被绑定上的那个值。

Variables we set here will be available to the breadcrumb template file.$variables

现在，我们使用模块提供了一个变量，还使用template.php文件中的函数提供了一个变量，那么实际中会使用哪个变量呢？

These problems can be seen : the number of variables broken down by the huge market, many variables breakdown between strong relevance to the effective impact of the marketing work; In the face of new economic forms, and more detailed variables needed; By the development of methods and tools needed to be further strengthened.

可以看出其中存在的问题：细分市场中的细分变量数目巨大，许多细分变量之间存在较强的相关性，影响了营销工作的有效开展；面对新的经济形式，更多的细分变量需要提出；细分方法和工具的开发需要进一步加强。

Weconjecture that in the canonical basis there must be enough polynomial ele-ments in multiple variable, which include independent multiple variable anddependent multiple variable.

我们猜测：在典范基中一定存在足够多的多变量的多项式元素，包括独立多变量的多项式元素和相关多变量的多项式元素。

From canonical correlation analysis of nine variable s of live traits and ten variables of carcass traits about ninety specimens of Hubei white pig, three canonical variables which determined the correlation between the two traits were obtained.

通过对湖北白猪新系90头样本的活体性状的9个变量与胴体性状的10个变量之间的典型相关分析，得出了决定两组性状间相关关系的三对典型变量。

RESULTS: The numeric type timing variance would be obtained in database with the way of variable chronometry. The timing would be kept as a document of textual form with the way of document chronometry. All the operations would be counted time with the above ways. CONCLUSION: EpiData has the function of counting time.

结果：变量计时法可以直接在原数据库中得到数值型计时变量，文件计时法则将计时结果另存为文本格式的文件。2种方法均能实现对每个变量、每条记录、每次操作数据库的数据录入过程进行计时。
