In this paper, interval models in the convex models are used to describe the parameters having uncertain but boundary limits such as stress and load. The shortest distance from coordinate origin to failure surface in the expand space of standardized interval variables is chosen as the non- probabilistic reliability index.
将具有不确定且有边界限制的应力、载荷等用凸模型中的区间模型来描述,取在标准化区间变量的扩展空间中,从坐标原点到失效面的最短距离作为非概率可靠性指标。

A DPLS discriminant analysis model was developed based on spectra region from 400 nm to 2 498 nm with mathematic pretreatment 2-8-6-1 and scatter correction treatment the standard normal variate. The accurate discriminant rate of calibration and external validation was 95.7% and 95.6% respectively. For the adulterated samples (MBM mass percentage≥5%), the accurate discriminant rate was 100%.
建立的判别分析模型:数学预处理方法为2-8-6-1,散射校正方法为变量标准化处理,光谱范围为全谱(408~ 2 492 nm),定标模型的正确判断率为95.7%,外部验证正确判断率为95.6%,对于掺入量≥5%MBM时,正确判断率为100%。

In order to improve the robustness and performance of calibration, several spectra preprocessing methods were employed, including standard normalized variate, multiplicative scatter correction and direct orthogonal signal correction.
为了有效消除土壤颗粒不均匀性所带来的散射影响,同时扣除与土壤品质参数无关的光谱信息,研究运用变量标准化、附加散射校正和直接正交信号校正等光谱预处理方法,使模型精度得到显著提高。

The NIRS quantitative analysis model was developed for measuring MBM content in fish meal by using partial least squares. The initial spectrum was pretreated by standard normalized variate, 7 point smoothind and one derivative respectively.
应用偏最小二乘定标方法,在8 678.10~4 250.34cm^(-1)波数范围内,采用变量标准化、7点平滑和一阶导数对光谱进行预处理,建立了鱼粉中肉骨粉含量的NIRS定量分析模型。

So the knowledge intensive business service sectors can be divided into standardistion KIBS and particularization KIBS extremely. However, our analysis also confirms that KIBS are tremendously diverse both between and within sectors.
另外,权变组织理论为本文探寻有效的控制变量提供有力的依据,按照Sundbo对服务业开发方式的描述,本文将研究对象极端地划分为定制化KIBS和标准化KIBS两类。

While defined in terms of variances and covariances, PCA is usually applied to standardized data since the results are sensitive to the often arbitrary choices of units of measurement used in a study.
就定义差异变量和协方差而言,PCA分析前通常要先标准化处理数据,因为,PCA对任意选择研究中的计量单元是敏感的。
