Translating Subtitles of American Films into Chinese: An Intertextual Analysis Approach
当今中国,中外文化交流日益频繁,译制片的观众日趋壮大,电影翻译因而成为翻译园地中愈来愈重要的领域,但翻译界对电影翻译的重视却远不如文学翻译,这与其社会作用极不相称。字幕翻译是广为接受的一种电影翻译形式。它与文学翻译的不同之处在于受到时空的限制。“时”指的是与画面同步,“空”指的是字数的限制。 本文包含“引言”、“结语”和其他五个章节。 “引言”简要介绍了本文中所涉及的主要问题:互文性,电影翻译和电影中的互文性。 第一章——“互文性:综述”——概述了互文性概念的形成和发展历程,并提出了一个互文分析的框架。本章旨在建立互文性与电影翻译的宏观联系。 第二章——“电影翻译”——...Synopsis This thesis consists of five chapters plus an “introduction” and a “conclusion”. In the “Introduction”, an overview is given to the major concerns of this thesis, i.e. intertextuality in general, film translation and intertextuality in films. Chapter One, “Intertextuality in General”, provides a literature review examining its development, and a framework for its analysis. This...学位:文学硕士院系专业:外文学院外文系_英语语言文学学号:20010400
Study on extraction technology of volatile oil from cortex phellodendri by supercritical carbon dioxide
使用超临界二氧化碳技术对经过超声-微波处理过的黄柏中的挥发油进行萃取,并对萃取工艺进行响应面优化。在单因素预实验的基础上,以萃取压力、萃取温度、萃取时间为响应因素,黄柏挥发油的萃取量为响应值,根据中心组合(bOX-bEHnkEn)实验设计原理,采用三因素三水平的响应面分析法,确定各工艺条件对萃取量的影响,并用扫描电子显微镜(SEM)对萃取前、未超声-微波处理超临界萃取后及超声-微波处理超临界萃取后的黄柏进行比较观察,对萃取效果进行了微观解释。结果表明,经过超声-微波处理过的黄柏中的挥发油超临界二氧化碳萃取最佳工艺条件为:萃取压力为34MPA,萃取温度为41℃,萃取时间为66MIn,萃取率达6.03%。The supercritical carbon dioxide extraction of volatile oil from processed cortex phellodendri was optimized by response surface methodology(RSM).According to the principle of Box-Behnken central composite design,extraction pressure,extraction temperature,extraction time were chosen as response factors,extraction mass was chosen as response value,and a three-factor and three level central composite design was adopted to determine the influence of various technological conditions.Using SEM observed the cortex phellodendri before and after extraction,and explained the extraction effects from microcosmic aspect.The results showed that the optimum extraction conditions were as follows:extraction pressure 34MPa,extraction temperature 41℃,extraction time 66min,extraction yield was 6.03%.湖南省科技厅重大专项(2008FJ1007);2010年吉首大学大学生研究性学习与创新性实验计划项目(JSU-CX-2010-49
重组人血管内皮生长抑制因子对人肺腺癌裸鼠移植瘤的放射效应影响
目的:探讨重组人血管内皮抑制因子(recombinant human vascular endothelial growth inhiloitor-192,rhVEGI-192)对人肺腺癌裸鼠移植瘤的放射增敏作用。方法:采用原核表达rhVEGI-192,获得目的蛋白。通过肿瘤倍增时间,计算药物的增敏系数。通过建立人肺腺癌裸鼠移植瘤模型,荷瘤裸鼠随机分为4组:对照组、10Gy、rhVEGI-192、rhVEGI-192+10Gy。采用6MV-X线进行照射,照射剂量为10Gy。获得移植瘤标本,利用免疫印迹法检测移植瘤中VEGF(vascular endothelial growth factor)的表达变化。结果:SDS电泳结果显示,目的蛋白位于22k D左右。10Gy照射时,重组人血管内皮抑制因子的EF(enhancement factor)值为1.5。和空白对照组相比,rhVEGI-192组和10Gy组移植瘤的生长受到抑制(P<0.001),rhVEGI-192+10Gy组移植瘤生长显著抑制(P<0.001),rhVEGI-192+10Gy组移植瘤较10Gy组有明显生长抑制。和空白组相比,rhVEGI-192组VEGF表达减少,而10Gy组VEGF表达变化不明显,rhVEGI-192+10Gy组VEGF表达明显减少。rhVEGI-192+10Gy和rhVEGI-192组相比,VEGF表达减少。结论:rhVEGI-192联合照射能够减少VEGF的表达。这可能是rhVEGI-192的增敏机制之一。中国人民解放军南京军区医学科技创新项目(编号:No.12MA061
LSNCCP:A Clustering Algorithm Based on the Largest Set of Not-Covered Core Points
聚类在数据挖掘、模式识别等许多领域有着重要的应用 提出了一种新颖的聚类算法 :一种基于最大不相含核心点集的聚类算法LSNCCP(aclusteringalgorithmbasedonthelargestsetofnot coveredcorepoints) 在密度定义的基础上 ,考察核心点之间的距离关系 ,定义相含、相交、相离这 3种核心点之间的关系 ,最后找出一个最大不相含核心点集 ,在此基础上进行聚类 ,并且找到解决丢失点问题的快速方法 该最大不相含核心点集只是全部核心点集合的一个很小的子集 ,因此有效地缩减了同类算法中搜寻核心点的时间 理论和实验上证明了这种算法的可行性和优越性Clustering is an important application area for many fields including data mining, pattern recognition, etc. In this paper, a novel clustering algorithm LSNCCP(a clustering algorithm based on the largest set of not-covered core points) is proposed. On the basis of the definition of density, the distance between the core points is discussed. And then, the three essential distance relation: covered core points, intersectant core points, and separate core points. Finally, the largest set of not-covered core points is found and based on the set the data can cluster very well. Because the largest set of not-covered core points is a lesser subset of the all core points, the new algorithm cuts short the time of searching all core points in the similar algorithms. The feasibility and the advantage or the new algorithm are proved in theory and experiment.福建省自然科学基金项目 (A0 3 10 0 0 8) ;; 福建省高新技术研究开放计划重点项目 (2 0 0 3H0 43
