The thesis consists of the followingmain results:the Cauchy's integral formula on certain distinguished boundaryfor LR regular functions with values in a universal Clifford algebra 〓,theCauchy's integral theorem,the mean value theorem,the maximum modulus the-orem.the Taylor's expansion,the Laurent's expansion and the residue theoremetc..

第一章叙述了泛Clifford代数基本理论，其中，我们首先准确而又富有创造性地给出了在泛Clifford代数〓上的一个对合运算表示，由此，我们给出了在泛Clifford代数〓上的一个内积，然后，我们借此给出了在泛Clifford代数〓上的相应的两个等价的范数，并证明了若在〓上赋予其中的一个范数，则〓是一个Banach代数。

Nozzle is one of the most important components used in SRM. The nozzle is subjected to the cautery and concussion of the heat gas, so the thermal effect and related thermal-structure couple effect to the nozzle structure become the important factor affecting the load carrying capability of the nozzle. Well, the following investigation contents are accomplished in this paper.

喷管是固体火箭发动机关键部件之一，喷管在工作过程中承受着高温燃气的烧蚀和冲刷，所产生的热效应和由此带来的热—结构耦合效应已经成为喷管强度和稳定工作必须考虑的重要因素。

Gerbrand Ceder and Byoungwoo Kang of the Massachusetts Institute of Technology hope to change this, and thus help make the electric car a work-a-day consumer item, rather than a high-end boy's toy.

麻省理工学院的Dr Ceder和 Mr Kang想改变这一点，由此帮助把电动汽车变成一个普通消费品，而不仅是一个奢侈的玩具。

In 1840, the British imperialists started the Opium War against China, completely breaking the Celestial Empire of China itself, enjoy the music of the era, to destroy China's culture, and a heavy blow to the Chinese people's national pride, China thus embarked on a downhill path .

1840年，英帝国主义发动了对中国的鸦片战争，彻底打破了中国天朝自居，安享其乐的时代，毁弃了中国的文化，沉重打击了中国人的民族自豪感，中国由此走上了下坡路。

The Lamborghini tractors were very reliable and they were built in a very high quality, mainly because over 80 percent of the parts were made inside the factory at Cento, so Ferruccio could asure himself of the best possible quality.

由此已经有80%的部件是在工厂中加工完成，甚至是流水线，所以Ferruccio本人可以保证其最好的质量。

By taking advantage of a corollary of the Desargues theorem and the corresponging extension of Desarguesian configuration, the concept of stereohomology has been defined in projective geometry and presented based on homogeneous coordinates. Consequently, a series of geometrical transformations, such as central projection, parallel projection, centrosymmetry, translation transformation, reflection, rotation transformation, which can be contained in it or derived from it have also been analytically defined.

利用Desargues定理的一个推论和引申的Desargues图形，给出"空间透射"在射影几何意义下基于齐次坐标表象的解析定义，从而解析定义了可蕴涵其中的中心投影、平行投影、中心对称、平移、反射等几何变换以及可由此衍生出的旋转变换。

The reasons causing elli ps e defect of centrifugally cast ductile iron pipes with large diame-ters were a nalyzed.

分析了大口径离心铸造球墨铸铁管产生椭圆缺陷的原因，并由此制定了相应的工艺措施应用于生产，取得了良好的效果。

In fact, this discovery filled the gaps of evolution from cephalopod to the vertebrate.

头索动物与脊椎动物之间的演化空白由此得以填补。

Potential maps could be useful as baselines to establish critical habitat in a productive ecosystem where speciation may be occurring,and to declare new protected areas for cetacean conservation in Venezuelan waters.

在一些高产的生态系统内新的物种可能正在形成，而这些潜在可能的分布图可以作为在高产生态系统内确立关键栖息地的标准，由此我们可以在委内瑞拉水域为鲸类建立新的保护区。

As a result, in recent years, new pulmonary drug delivery system without CFC has gotten great advances.

由此也促使不含CFC的新型肺部药物传递系统取得了重大发展。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
