In this paper a genetic algorithm four-dimension data assimilation system was applied to the more complex MM5 model, we verify the performance of the genetic algorithm assimilation system, we take the a heavy rainfall process during 04-05, July, 2003 as the experimental research object, and carry out data assimilation experiment of actual observation data, compare the experimental results of the genetic algorithm assimilation system and MM5 adjoint model assimilation system with the experimental results without assimilation, the following is the result:genetic algorithm assimilation system is used not only in a barotropic primitive equation but also in the complex model, MM5, for example, in the ideal experiment the result of the genetic algorithm assimilation system is better than the MM5 adjoint model assimilation system, in the assimilation experiment of actual observation data, whichever assimilation system is used, the initial field of numerical prediction model is effectively improved and the prediction effect of physical field and rainfall are somewhat enhanced.

本文将遗传算法的四维同化系统运用到更复杂的MM5模式中，在理想实验中验证遗传算法同化系统的性能，并以2003年7月4日"南京暴雨"作为研究对象，进行了实际观测资料的同化，并将遗传算法同化系统和MM5伴随模式同化系统得到的结果跟未同化的结果进行了比较，结果如下：遗传算法同化系统不仅可以用在正压原始方程模式上，同样也可以用在MM5等复杂模式上，理想实验证明了遗传算法同化系统优于MM5伴随同化系统，在实际观测资料同化中，采用两种方法的同化系统都能有效地改善数值预报模式的初始场，能在一定程度上提高物理量场和降水量的预报效果。

The system gets two image of one object with two CCD, thus obtains depth from two CCD"s parallax. After investigating the operation spot and discussing with surgeons we use LED as markers, and get the marker"s 3-D position with a non-contact optics orientation method. After calibrating the CCD, processing the image, the system can figure out marker"s areal coordinates, get marker"s 3-D coordinate in dummy world coordinate system, thereby obtain instruments 3-D position and orientation. After the coordinate transformation and a series of orientation calculation, operation navigation comes true.

运用两个摄像机对同一目标从不同位置成像，进而从视差中恢复距离；通过对手术现场的仔细了解与手术医师的反复商榷，使用LED作为标志点，利用非接触式光学定位方法提取空间点位置信息：通过对摄像机的标定、图像处理及目标点重心的计算，求出空间点在虚拟世界坐标系下的三维坐标，从而确定了手术器械等的空间位姿，通过空间坐标转换及一系列定位计算，完成了手术导航实验系统。

" The Greek military leader and historian Xenophon, who served with Greek mercenaries in Persia, first used the Greek word paradeisos adopted from the Avestan word to refer to the Persian kings' and nobles' parks or pleasure grounds. This Greek word extended to mean "garden" or "orchard was an obvious choice for translators of the Bible into Greek to use both for the Garden of Eden and the Abode of the Blessed, or heaven. The Greek word was adopted into Late Latin and was used much as we might expect in its biblical senses in ecclesiastical Latin. The Old English word paradis taken from Latin is found, but our word probably really established itself in Middle English (first recorded before 1200), derived both from Latin and from Old French, which had adopted the word from Latin. paradise.

曾随希腊雇佣军到波斯服役的希腊军事将领和历史学家色诺芬，首先使用了希腊语词paradeisos，，该词采用了阿维斯陀词，指波斯国王和贵族们的花园或游乐场，这个希腊词衍生到表示"花园"或"果园"，显然是译者在把《圣经》翻译成希腊文时所做出的选择，以用来表明伊甸园和天国或天堂，有这两种含义的希腊词被引入后期的拉丁语中且当它们在教会拉丁文（后期拉丁语paradisus 中意为《圣经》方面的意义时被更广泛地使用，古英语paradis 一词来自拉丁文，但我们用的这个词可能在中古英语（首次记录在1200年前）中真正确立了起来，人们发现它源于拉丁文和从拉丁文中采纳了这个词的古法语

Somewhat paradoxically, there was also a renewed enthusiasm for contemplation, and the era produced two of the greatest representatives of Mysticism - Teresa of Avila and John of the Cross.

有点自相矛盾的是，还有一个重新的热情沉思，和时代产生的两个最大的代表神秘主义-德肋撒的阿维拉和约翰的交叉。

Indeed there is a closer connection between Ingres's Napoleon and Antoine-Franois Callet's 1789 portrait of Louis XVI—in velvet, silver slippers and powdered perruque , it surely represents the last gasp before the revolution—than between the two versions of Napoleon that were painted only six years apart.

事实上，虽然两幅拿破仑肖像之间只相差六年，比起达维特的作品，安格尔的拿破仑画像更近似于安东尼-弗朗西斯·迦莱特（Antoine-Franois Callet）于1789年所作的路易十六的肖像。画中路易十六身穿天鹅绒礼服，银丝软鞋，戴着扑粉的假发，在革命到来之前作着最后的残喘。

Firstly establishing mechanical model of casing structure , and then processing casing forces analysis using space finite-element method and superposition method(put structure stress and outer force stress together), it computes the stress of casing in three dimensions, and gets the internal force and transmutation. The structure of casing-coadjutor is computed overlaply and the question of contact is solved. In the aspect of design, it provides the mixed integer-discrete variable optimization method of casing cross section size and coadjutor layout.

本文就上述两个问题的最优化设计展开研究，首先建立了套管结构的力学模型，进行套管的受力分析，用了空间有限元法和叠加法(结构应力和外载应力相叠加)，对套管进行三维计算，确定结构的内力和变形，对套管—扶正器结构进行整体的叠代计算，解决接触问题；在设计方面，提出了解决套管截面尺寸参数和扶正器布局的混合整数—离散变量优化方法。

Describing the problem of two dimension fuzzy decision existed in the engineering, the concepts of core set and support set are proposed. Using feasible set to constitute corelation between two sets, determinant theorem is presented to judge if the decision can be realized according to the feasible degree.

描述了工程中存在的二维模糊决策问题，提出了决策的核心集和支撑集的概念，用可行集建立了两个集合间的关联，提出以决策的可行度作为决策能否实现的判定定理。

The thesis resorts to the methods of deduction and counterevidence to demonstrate the defects of textualist and contextualist stylistics both theoretically and practically. Then it puts forward an analytical model, which incorporates them.

文章首先用演绎和反证的方法，从理论和实践两方面指出了文本主义文体学和语境主义文体学的缺点，然后提出了一种有机结合这二者的综合分析模式，并用该模式分析了安德鲁·马韦尔的《致羞涩的情人》，威廉·布莱克的《伦敦》和乔治·欧维尔的《绞刑》等三篇作品。

A Cinema-Goers Autobiography" gives a mesmerizing account of the years of Calvino's adolescence, when he attended the cinema "almost every day and maybe even twice a day," riveted by such films as Lives of a Bengal Lancer with Gary Cooper and Mutiny on the Bounty with Charles Laughton and Clark Gable."

观众回忆录》给出了一段对卡尔维诺青少年时代迷人的描述，那时他去电影院&几乎每天一次，有时甚至一天两次&，被加里·古柏扮演的孟加拉骑兵的生活和查理斯·兰顿和克拉克·盖博为奖金而发生的叛变所牢牢吸引。
