Chapter 1 briefs the relation between invariance and computer vision and summarizes the research and application of invariance in computer vision. Chapter 2 first derives the transformations of three camera models, then makes the correpondences between the models and three typical geometrical transformation groups by analysing the transformations respectively. The correspondences supply the theoretical basis for applying geometrical invariants to resolve the problems of computer vision. In Chapter 3, we describe the geometrical invariant theory and prove some geometrical invariants of coplanar points, lines or conics by algebraic method. In order to use the invariants of conic pairs to describe general 2D shapes, we discuss the perspectively invariant representation of planar curves using conies in detail. A system consisted of two TMS320C25 and based on moment invariants is introduced in Chapter 5. The system can recognize more than 30 different shapes of object model or more than 10 plane models with similar shape in real time.

第一章简述了不变性与计算机视觉的关系，以及计算机视觉中的不变性研究和应用概况；第二章推导了计算机视觉中常用三种投影模型的变换关系，通过对这三种变换关系的分析，分别建立了这三种投影模型和几何学中的三种变换群之间的一一对应关系，为几何不变性在计算机视觉中的应用提供了理论基础；在第三章中，我们介绍了几何不变性的理论，并且用代数方法证明了共面点、直线、二次曲线的几何不变量和射影不变量；为了把二次曲线的不变量用于一般二维形状描述，在第四章中我们详细地讨论了用二次曲线实现一般平面曲线的透视不变性表示的方法；第五章介绍了用两片TMS320C25构成的、基于不变矩形特征的运动目标实时识别系统。

The calculating accuracy is ensured by expelling oddity points from the results.

在第3章，重点研究了汽轮发电机组转子扭振机理和数学模型，特别是汽轮机特殊结构的模化方法，编写了计算程序，计算了某型300MW汽轮发电机组转子和试验台转子扭振特性。

For eliminate redundant stress in spring unit brought by continuously variation of strain,in wind spring device,the adopt spiral output wheel with continuously variant radii was used and the variation of moment can be canceled out by variation of radii,the approximate constant output force can be obtained.

为消除弹簧装置中应力随应变不断变化而产生的多余应力，在卷簧结构中，采用螺旋变径输出轮，用半径的变化抵消力矩的变化，获得近似恒定的输出力。在精度要求不高的场合，采用此方式可形成简便可靠的近似恒力的弹簧装置

Recently,atoms with higher order vanishing moment were defined by Krant-z etc on some particular spaces of homogeneous type,but it hasn't been solvedthoroughly on usual spaces of homogeneous type.On the other hand,krantz'sstudy was made under the condition which the measure of the sets constructedby single element is zero,therefore their work didn't include the case of integ-er Z as a particular space of homogeneous type.Indeed,as a Hardy space on Z,〓(0＜p≤1)has been studied by some scholars.

尽管近来Krantz等人在某些齐型空间上定义了带高阶消失矩的原子，但在一般的齐型空间上建立带高阶消失矩的原子Hardy空间还没有完全解决，而且Krantz等人的工作是在单点集测度为零的条件下讨论的，因而不包括作为齐型空间的整数Z的情形。Z作为一类特殊的齐型空间，其上Hardy空间〓的问题有不少学者讨论过。

As Shakespeare knew, love burns high when thwarted by obstacles. In Twilight, an exquisite fantasy by Stephenie Meyer, readers discover a pair of lovers who are supremely star-crossed. Bella adores beautiful Edward, and he returns her love. But Edward is having a hard time controlling the blood lust she arouses in him, because--he's a vampire. At any moment, the intensity of their passion could drive him to kill her, and he agonizes over the danger.

这个故事描写离开母亲与父亲同住的高中女生Bella，来到陌生的小镇与学校，本来以为学校生活一定充满压力，没想到遇到了白马王子Edward，不过没有料到的是，Edward是吸血鬼族群的一员，他压抑著渴望鲜血的欲望，爱上了人类，而该故事除了人类与吸血鬼之间的爱情故事之外，更增加了狼人与学校之间的势力政治的现实。

The Rossoneri struggled to make themselves dangerous. The first dangerous moment came in the 18th minute, when a shot by Pato troubled Bassi quite a bit. A minute later, the Empoli keeper was again a protagonist, as he failed to hold onto a cross by Oddo, and Pato was ready to take advantage.
