In this paper, we give explicit constructions and formulations for harmonic maps from R1,1 into classical real semisimple Lie groups by using Darboux transformation. We also discuss pluriharmonic maps from complex manifoldsinto symmetric spaces and Willmore surfaces in Sn. By converting geometric conditions satisfied by these maps into integrable systems, and using the the-ory of integrable systems, we give explicit constructions for pluriharmonic maps from complex manifolds into symmetric spaces and the Willmore surfaces in Sn respectively. Finally, we classify hypersurfaces in Sn+1 with three distinct prin-ciple curvatures and zero Mobius form using the theory of Mobius geometry. The paper consists of four chapters.

本文首先利用Darboux变换的方法给出了从Lorentz平面R~(1，1)到经典实半单Lie群的调和映照的具体构造，并给出其显式表示；其次研究了复流形到对称空间的多重调和映照及球空间S~n中Willmore曲面，将这些映照所满足的几何条件转化为可积系统，然后利用可积系统理论分别给出复流形到对称空间的多重调和映照与S~n中Willmore曲面的构造；最后利用Mōbius几何的理论给出S~(n+1)中具有三个不同主曲率且Mōbius形式为零的超曲面的分类。

Ryan Kisor, one of the best jazz trumpeters in the world, was born April 12th, 1973 in Sioux City, Iowa. He began playing in a local dance band by the age of ten, began classical lessons at 12, met and was inspired by Clark Terry at 15 (while attending the latter's summer jazz camp) and played with various high school all-star bands. In November of 1990 he won the Thelonius Monk Institute's trumpet competition at the age of just 17, beating out the likes of Nicholas Payton and Marcus Printup. After graduating from high school in 1991, he went to the Manhattan School of Music and later studied with Lew Soloff among others. He has recorded fairly extensively both as a leader and sideman and with small and large groups. Among the highlights; the Mingus Big Band (which still plays every Thursday night at "The Fez" under Time Cafe in NYC's east village), the Michel Camilo Big Band (which although only existed for the purpose of recording the album,"One More Once," was arguably one of the best latin big bands recorded in recent memory), the Lincoln Center Jazz Orchestra, Gerry Mulligan, Wynton Marsalis, Wycliffe Gordon, Horace Silver, and Walter Blanding.

Ryan Kisor，美国著名爵士小号演奏家，1973年4月3日生于美国爱荷华州，10岁开始学习小号演奏，1990年在美国竞争最为激烈的爵士乐比赛——Monk国际爵士乐大赛（International Thelonious Monk Jazz Competition）中击败像Nicholas Payton和Marcus Printup这样的高手获得优胜，当时年仅17岁。1991年中学毕业后，被著名学府曼哈顿音乐学院录取师从Lew Soloff先生学习小号，在学期间加入Mingus大乐队，年纪轻轻便以惊人的深厚实力成为独当一面的独奏小号手。19岁时以首张专辑《One For Miles》正式出道，而后自1994年至今一直为世界著名爵士小号演奏大师Wynton Marsalis领衔的林肯中心爵士乐团的常任小号演奏家，同时Kisor先生还受聘加入卡内基音乐厅爵士乐团以及David Matthews率领的曼哈顿爵士乐团，杰出的演奏技巧及艺术水准受到世界乐坛之瞩目，曾受邀多次出访全球各国，每次均毫无保留的展现了其精湛的演奏实力，让世界各地的广大乐迷感受到其小号的魅力。

Methods Ninety elective patients undergoing general anesthesia for hysterectomy were randomly assigned to two equal groups. GroupⅡreceived endotracheal intubation protected by sterilized transparent sleeve while groupⅠcorrespondingly adopted unprotective classical endotracheal intubation. Endotracheal swab sampling and bacterial counting were performed on the principle of aseptic processing before endotracheal intubation and extubation, respectively.

90例在全身麻醉下行择期全子宫切除术的患者随机分为两组，每组45例，Ⅰ组采用传统的气管插管操作方法，Ⅱ组采用无菌透明隔离套保护的气管插管操作方法，在气管插管前和拔管前分别按照无菌操作原则实施气管内试子取样，进行菌落计数。

120 patients were divided into two groups randomly. We adopt the classical surgical procedures in the first group but make use of improved high thread drawing method.

将高位肛瘘患者120例随机分为二组，第一组采用经典的术式治疗，第二组采用改进后的高挂低旷术式治疗，并将二组疗效及并发症进行对比。

120 patients were divided into two groups randomly. we adopt the classical surgical procedures in the first group but make use of improved high thread drawing method. then we compare them with clinical effect and postoperative complications.

An automatic algorithm was used in the analysis to identify clusters of groupings of patients. We used the classical unsupervised clustering method called the Iterative Self-organizing analysis technique of DATA analysis originally introduced by Ball and Hall.25 The technique allows the splitting and merging of clusters while trying to find the "best" configuration. It therefore, requires very little a priori knowledge about the data and predefining the possible number of clusters or groups is not required. The range of possible minimum and maximum number of clusters within which the algorithm can search for an optimal configuration was determined by a procedure called the chainmap which reorders the multidimensional data in the form of a 2D distance map.26 A patient vector is randomly selected and its nearest neighbor is identified as that with the shortest distance between the 2 patients' vectors.

使用自动算法来分析鉴别患者组的聚类，我们使用经典的最初由Ball和Hall提出的的非监控聚类方法，该技术允许在寻找&最佳&形态使对聚类进行拆分和组合，他不需要对数据专门的知识和对聚类或群的可能数量进行预设，在聚类可能的最大和最小范围内，算法可以通过一个叫Chainmap的程序寻找最理想的形态，该程序记录了来自2D距离图的多维数据。
