The result was the same entirely. Explanation was set forth to samples of wrong classified.The datum of circulating supply water quality was centralized. Principal component matrix was rotated through factor analysis. Hierarchical cluster of multiple class was realized through factor after rotation. Key factor of influencing cluster was searched. The recipe was recommended and worked well.

对20家企业循环冷却水系统的补充水水质指标先进行均值中心化，然后用因子分析对主成分进行旋转，用旋转后的因子进行了多类的系统聚类，找出了影响聚类的关键因子，为水处理剂配方的初步推荐提供了一种切实可行的方法。

The correlation among all these parameters of four different types of wear debris is conducted. In the analysis of surface texture, the maximum and minimum brightness point in texture normal line is examined firstly. Then, the differences among some typical wear particles are analyzed through analyzing the texture gray level co-occurrence Matrix, color principal component analysis of the wear particle and the direction of wear particle outline.

在磨粒表面纹理分析中，通过检测磨粒表面纹理法线上亮度极小、极大值的纹理分析方法分析了滑动磨粒与疲劳磨粒差别，通过灰度共生矩阵进行纹理分析四种不同类型的磨粒图像，通过主成分分析分析方法对磨粒颜色特征进行识别，以及根据磨粒轮廓方向判断磁性磨粒和非磁性磨粒。

Among the normal methods, principal component analysis method could use more band information than the post-classification comparison method and subtration images method. And its accuracy was higher than the other two methods.

主要研究结论： 1、常规监测方法中，在数据预处理方法一致的前提下，主成分分析法能够利用较多的波段信息，并获得了比分类后比较法、图像差值法更高的精度。

The principal component time series of rotated EOF were used to classify the distributions of ozone concentrations into 15 patterns by cluster analysis.

本研究中并将REOF的主成分时间序列以群集分析的华德法分为十五个类组，以探讨臭氧事件日的污染型态，除了求出各种型态的臭氧特性外，还建立转换表，得到臭氧型态在连续两日转换的机率，由此表可以看出臭氧型态具有相当高的持续性。

The EOF loadings corresponding to the five highest eigenvalues were used to delineate the air quality regions. The results of EOF method were difficult to interpret because they tend to cluster most stations into the first group. The results obtained by rotated EOF and cluster analysis are similar and more reasonable. It is interesting to note that the clustering results based on 1h and 8h data are similar. The principal component time series of EOF and REOF were analyzed to determine their temporal characteristics.

EOF和REOF法中均采用特徵值为最大的五个EOF负荷作为分区的依据，以EOF划分均质区后容易将大部份测站划为同一区而造成解释困难，而采用REOF方法和群集分析法所得结果相似且较为合理，利用最大小时与八小时臭氧浓度进行划分结果接近，本研究也针对EOF和REOF所求出的主成分时间序列加以分析，以了解其特性。

Although translator has turned from being a crystal ball by which the original culture can unrestrainedly penetrate to another crystal ball by which the target culture can freely traverse, the translator's personal embodiment, in the process of cognitive act, are still absent in translation studies. Translators are still subjects without body or simply disembodied subjects.

译者虽然由原语文化可以自由穿透的玻璃球变成了译语文化可以自由穿越的玻璃球，但译者认知过程中的个体体验在翻译研究中依然缺席，译者依然仅仅是一个没有躯体体验的主体。

Chillingly, he claimed our technology is 'not nearly as sophisticated' as theirs and "had they been hostile", he warned 'we would be been gone by now'.

令人毛骨悚然的，他声称我们的技术是'并不那么复杂，像他们一样，和"如果他们敌意"，他警告说，'我们将现在已经过去了。
