The author also investigates Geo~coordinate transformation and similitude/affine transformation. Having accomplished the design of functions of spatial reference system, the author defines and designs the interfaces, component classes and then implements the component framework.

研究了关于大地坐标系转换和平面坐标的相似和仿射变换理论，在完成空间参照系统的功能设计的基础上，定义了空间参照系统的接口和组件对象，并设计和实现了这一系统。

There are three main methods in face localization: localization according to face outline, localization according to complexion and localization according to templates constructed by some standard sample images. As to feature extraction, it can be divided into two parts because face features can be divided into geometrical features and algebraic features. While extracting geometrical features, the features of eyes, nose, mouth, eyebrows can be gained by some image processes: binary, sharpen, smooth, projection, calculating gradient and so on. In order to extract algebraic features, we can do some mathematical transformation for the digital images such as singular value decomposition, K-L transformation.

在人脸检测部分，目前存在的方法有利用人脸的几何轮廓进行检测、利用人脸的肤色信息进行检测、构造标准人脸模板进行匹配检测等等；在人脸特征提取部分，可以用一些图像处理的方法如投影、二值化、求梯度图像等提取人脸中各特征器官如眼睛、鼻子、嘴巴等的几何特征，另外也可以借助于数学变换，求取人脸图像的一些代数特征，如对图像进行奇异值分解，以奇异值代表图象的特征，或对图像进行K-L变换，以图像在构造的特征空间上的投影系数作为图像的特征等；在识别部分，可以通过距离度量或相似度来判断输入图像与样本图像的匹配程度，还可以通过神经网络方法进行人脸的识别。

This paper gave the detailed reviews on previous research results on contaminant transportion and transformation, and pointed the unsolved problems and direction of the research. Analytical solation, numerical modeling and physical tests were used to investigate contaminant transportion and transformation in soil and groundwater in present study.

本文在评述污染物迁移转化研究进展的基础上，分析了现有成果的存在问题和研究的发展趋势，采用了数学模型解析计算、数值计算和物理模型试验相结合的方法，对污染物在土壤及地下水中迁移转化规律进行了深入研究。

The transformation relationships among the various physical quantities measured from O and S are known as stretching transformation.

从O、S测得的各种物理量之间的变换关系称为伸缩变换。

The basic view of the model that the intense subduction of the Indian plate beneath tbe Eurasian plate would result in inhomogeneity of the fabric and deformation of the lithosphere and repeated alternations of normal transformation from collision to contraction to stretching and reverse transformation from stretching to contraction.

其基本观点是强调由于印度板块向欧亚板块的强烈俯冲造成岩石圈组构和变形的不均一性及岩石圈中存在的碰撞→收缩→伸展的正向转变和由伸展→收缩的逆向转变的反复交替。

This is not a dramatic or theatrical transformation, but a surreptitious transformation.

这种变形不是一种戏剧化或舞台化的变形，而是一种暗中的变形。

Results On day 2 after injection, the lymphocyte transformation rate of piglets injected with LPS were significantly (P.01) increased compared with piglets injected with saline. The lymphocyte transformation rate of Laiwu piglets were raised significant than Yorkshire piglets (P.05). Effects of immunological stress on the level of swine plague antibody had not significant difference in different breeds of piglets.

结果］猪在LPS后的第2天，其淋巴细胞转化率显著高于生理盐水组(P.0l)，莱芜猪的淋巴细胞转化率显著高于大约克夏猪(P.05)；免疫应激对不同品种仔猪的猪瘟抗体水平无差异性影响。

There's no problem with transformation itself, however, when artists just see the surface of those scientific problems and try to prove the truth of what they saw through paintings, the concept will turn into textuary science in the process of transformation, meanwhile, the painting will become passive and attaching help text for knowledge propagation.

转向本身并不存在问题，但如果艺术家只认识到其它学科问题的表层，并试图用绘画来证明所见所知的真实与正当，使得观念在转化的过程之中变成了文本式的科学，那么绘画在此时变成一种被动的、附属的、用于传播知识的文字说明。
