An adaptive grid scheme controlling cell area is used to generated grids in the divergent section of symmetric annular nozzle, and the generated grids are used in the flowfield calculation through the uncoupled way. The elliptic equations are used to generate grids in three dimensional regions of FDN divergent section, the source terms used in the equations employ a mathematical form which is independent of the boundary shape and of the boundary grid point distribution, the free parameters contained in the source terms are determined by the two restraint conditions, the intersection angle of transverse grid lines with boundaries and the local curvature of the transverse grid lines at the boundaries, and the interior grid distribution controlled directly by the grid point distribution assigned on the boundaries is realized, it makes the grid more clustering near the nozzle wall. For the generated grids in the whole computational regions have a good smoothness and orthogonality, the accuracy of calculation in the flowfield is ensured.

对轴对称的环形喷管采用控制网格面积的自适应网格方法对扩散段部分进行了网格生成，并通过非耦合方式应用于喷管的流场计算中；对强制偏流喷管扩散段内的三维区域采用椭圆型方程进行网格生成，方程中的源项采用了与边界形状和边界网格点分布无关的数学形式，源项内的自由参数由横向网格线与边界的交角及横向网格线在边界处的局部曲率两个约束条件来确定，实现了由边界上的网格分布直接控制内部的网格点，使壁面附近具有较密集的网格，并且在整个计算区域内的网格都具有良好的光滑性和正交性，从而保证了流场计算的准确性。

The works in the project just done can be summarized as five respects.(1) A device was designed to fabricate the asymmetrical resonant cavities by a pendant drop. A series ARCs with variable parameters provides a valuable experimental method for investigating the characteristics of ARCs.(2) The relationship between the number of active modes and the shape parameters in an ARC was investigated. The experimental lasing threshold was compared with theoretical result, the good agreement between two shown that it was the decrease of the number of active modes in an ARC that decreased lasing threshold.(3) Dye lasing gain was used to enhance the signals of stimulated Raman scattering of the weak gain Raman modes in a circular cavity made by a pendant drop, the instantaneous SRS spectra of weak gain Raman modes in ethanol was obtained by this new method.(4) The SRS signals of minority compound in a binary chemical complex was obtained by using dye lasing gain method. The detection concentration of minority compound was reduced to an order compared with normal SRS method.(5) A cylindrical circular cavity was formed by a liquid jet, which was used to reduce the pump intensity required for laser induced plasma spectroscopy. The limit of detection of trace element in aqueous sample was greatly decreased by this new method.

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。

As to the formation and evolution of the motives in classical fictions, our viewpoints are: the FuXi custom had engendered an extremely rich repertory of motives, such as JianDi pregnancy legend in the Shang Dynasty, which was the earliest form of the "Swan Maiden" type stories in the world. This type of the story later in the Jin Dynasty evolved into the Maiden-bird type story, which again involved into many other stories in which maidens took the shape of an egret, a swallow, a snail, a tigress, a fairy maiden or a girl in lotus leaves. The custom of HanShi or QingMing may be embodied in the stories about encountering with a girl reviving from a tomb. The dragon in classical fictions may be disguised into an ox or trees, whose fight on fifth of May was a counterevidence of DuanWu.

至于古小说母题的生成和演化方面，我们也许可以认识到：以上巳为主的祓禊风俗产生了最为丰富的小说故事母题，如殷商时期的简翟生子传说是世界上最早的"天鹅处女"型故事，它在晋代又演化为女鸟故事；而那些鹤女、鹄女、鹭女、燕女、螺女、虎女、荷衣女等故事，则在不同程度上是"天鹅处女"型故事的变型型式；在同异境女子遇合的故事中，郑交甫神遇江妃二女、世间男子巧遇仙境女子的故事都包藏着上巳习俗的内涵，而幽婚故事更多地带有寒食、清明风俗的痕迹；古代盛传的金牛故事、青牛故事不但可以归属龙类故事，而且在很大程度上与端午厌胜蛟龙的巫术有关，至于龙斗故事则明显地和端午习俗相联系，甚至可以由此反证端午驱龙的本意。

The notable proliferation was not observed by eyes in the local of injection. The infiltration of inflammation cells and mild proliferation of fibrocyte around dura mater was observed by HE stained in 4 and 8 weeks after injection. Infiltration and exudation of inflammation cells was observed by HE stained in epidural nerve root. Compared with group A, no changes of group B, C and D were observed under specific stained. Proliferation of type Ⅱ collagen fibers around dura mater was seen under immunohistochemical stained in 4 and 8 weeks after injection. There is no significant demyelination changes under LFB stained. The thickness and shape of the myelin sheath in epidural nerve root was not regular under transmission electronic microscopy in 4 and 8 weeks after injection. Fibroblast was also seen there. In nerve endometrium, macrophage could be seen under TEM, myelinated nerve fiber changed significantly, but nonmyelinated nerve fiber changed mildly. When 8 weeks, the changes of group D is smaller than the group B and C.

His hat a silk one was inadvertently knocked off and, as a matter of strict history, Bloom was the man who picked it up in the crush after witnessing the occurrence meaning to return it to him (and return it to him he did with the utmost celerity) who panting and hatless and whose thoughts were miles away from his hat at the time all the same being a gentleman born with a stake in the country he, as a matter of fact, having gone into it more for the kudos of the thing than anything else, what's bred in the bone instilled into him in infancy at his mother's knee in the shape of knowing what good form was came out at once because he turned round to the donor and thanked him with perfect aplomb , saying: Thank you, sir , though in a very different tone of voice from the ornament of the legal profession whose headgear Bloom also set to rights earlier in the course of the day, history repeating itself with a difference, after the burial of a mutual friend when they had left him alone in his glory after the grim task of having committed his remains to the grave.

他的帽子冷不防被碰掉了，看到这副情景并在混乱中拾起帽子以便还给他的正是布卢姆。这是确凿的历史事实。巴涅尔气喘吁吁，光着头，当时他的心已飞到距帽子不知多少英里以外。敢情，这位先生生来就是注定要为祖国豁出命去干的。说实在的，首先就是为了荣誉而献身干事业的。他幼小时在妈妈腿上被灌输的周全礼节已渗透到他骨子里，这当儿突然显示出来。他转过身去，朝递给他帽子的那位十分镇定地说了声："谢谢你，先生。"当天早晨布卢姆也曾经提醒过律师界一位名流，他头上的帽子瘪了。巴涅尔的声调可跟那人大不一样。历史本身重复着，但反应并不尽同。那是在他们参加一位共同朋友的葬礼，完成了把他的遗体埋入墓穴这桩可怕的任务，并让他孤零零地留在荣光中之后。
