But these methods limited by the expense of computing fundamental matrices and trifocal tensors or of the nonlinear optimization involved in computing epipolar tangencies. Through the studies of the invariants of the single axis motions, computational theories have been developed in this thesis to provide practical solutions for the problem of structure and motion from fitting the corresponding points in the whole sequence to its conic locus or conics for short.

在最近的研究中，一些研究人员利用视觉几何的方法从非定标的图象中对单轴旋转运动进行分析，提出了利用基本矩阵和三焦距张量求解单轴旋转运动中的关键参数——旋转角度的算法，但是该算法需要计算一系列相邻2图象的基本矩阵和一系列相邻3图象的三焦距张量，由于每个基本矩阵的自由度为7，每个三焦距张量的自由度为18，导致算法参数数量非常之大。

The simulation result shows the collection efficiency of TIR lens model is 67% when the angle of light is confined within 15°. And the uniformity on observation screen is improved in some degree. The optimal design of TIR lens further provides the development space of LED micro-projection display system.4 On the base of the theory research and the model simulation, four projection display systems which have LCOS as micro-display panel and which combine different optical devise for UHP and LED light source respectively are proposed in this dissertation. And the quality of projection display system is evaluated by thesimulation outcome.

在对静态画格的表现力研究时，根据画框与主体的关系，主体与陪体的关系、主体与背景的关系以及观众与画格的关系，主体本身的性质：大小、形状、色彩、空间感等因素，分别对画格的构图的表现力、景别的表现力、角度的表现力进行研究，把运动镜头整合为两个大的类别，分析了这两类运动镜头的表现性；最后，建立一个模型来论证，一部影片的表现性是在大量的具有表现力画格感应出一个表现力场的过程中完成的。

According to the morphological characteristics of cementite lamellae, the deformed pearlite can be divided into three kinds: irregularly bent lamella (pearlite lamella originally inclined with large angles to the rolling plane and irregularly bent after deformation); coarse lamellae with shear-band (the rhomboidal blocks of weakly deformed lamella bounded by shear band) and fine lamella (heavily deformed lamella aligned parallel to the rolling direction with fine interlamellar spacing).

按渗碳体形态特点，变形珠光体组织可分为以下3种类型：(1)不规则弯曲片层型，即变形后的渗碳体与轧制面呈大角度偏离且不规则弯曲的珠光体。(2)带有剪切带的粗大片层型，即被渗碳体剪切带分开且变形轻微的珠光体。(3)精细片层型，即与轧制方向平行排列、片间距细小且渗碳体严重变形的珠光体。

Experimental expressions are obtained when the vertically inclined angle of steel webs changes, and they can be used for bridge design.

Pacific plate subduction was dominated in study area since late Jurassic, stress regime was then transited from compression into extension associated with the steepening of subduction angel and retreat of subduction zone ocean inward; due to the difference in basement properties, extensional rifting basins dominated by depression basins developed within the Yangtze block, while volcanic faulting bounded basins for the Cathaysia block, and a series of red faulting bounded basins with half graben shape for the areas within the boundary zone between these two blocks.

晚侏罗世以后，太平洋板块对研究区的影响占主导地位，随着俯冲角度的变陡和俯冲带向洋的后撤，全区由挤压为主转变为以拉张为主的应力环境，由于基底属性有所差异，在扬子地块区域形成以拗陷盆地为主的伸展裂陷盆地，在华夏地块区域形成了火山断陷盆地，而在两大地块边界附近，则形成了一系列半地堑式的红色断陷盆地。

Sally had gone to the small mirror which hung in a corner of the kitchen, and was hastily smoothing her hair and setting her frilled cap at its most becoming angle over her dark curls; then she took up the tankards by their handles, three in each strong, brown hand, and laughing, grumbling, blushing, carried them through into the coffee-room.

萨丽走到厨房角落里的一面镜子前，迅速梳理她的头发，戴上那顶有饰边的帽子，将其调整到与她一头黑色卷发最搭配最好看的角度；接着握着大啤酒杯的手柄，每只褐色而有力的手三个，笑着，抱怨着，脸上泛着红晕地径直走进咖啡室。
