科技翻译练习二 II: 汉译英 VR（虚拟现实）技术可广泛的应用于城市规划、室内设计、工业仿真、古迹复原、桥梁道路设计、房地产销售、旅游教学、水利电力、地质灾害、教育培训等众多领域，为其提供切实可行的解决方案。 在先进制造业领域，站在大飞机发动机的3D影像面前，“可任意拆卸”这个虚拟现实的强项表现得淋漓尽致。操作人员可以把虚拟发动机的许多部件逐一拆下，再进入发动机内部。“虚拟现实”实现了跨平台的交互式设计、虚拟展示、虚拟装配、CAE数据可视化等功能，大幅提高设计团队的设计效率，使研发人员能及时发现、修正设计缺陷和潜在的工艺问题，提高产品开发的制造成功率。 虚拟现实技术在教育培训领域也大有用武之地。为真实实验不具备或难以完成的教学功能创造条件。在涉及高危或极端的环境、不可及或不可逆的操作，高成本、高消耗、大型或综合训练等情况时，虚拟现实技术能提供可靠、安全和经济的实验项目。华东理工大学的G-Magic虚拟现实实验室，就是高校虚拟现实教学的一个范例。该实验室拥有CAVE洞穴式虚拟现实系统，可以把大学生设计的作品投影到墙面、天花板和地面上。比如，学生设计了一间淋浴房，他能利用这套系统把它展现在实验室里，和真实的淋浴房一样大小。营造出这种教学环境后，教师就能与学生更方便地交流各个环节的设计优劣，并随时做出修改。 企业的一些培训项目，同样离不开HYPERLINK "https://www.360docs.net/doc/7c8632781.html,/view/7299.htm" \t "_blank" 虚拟现实 。以石油化工为例，众所周知，大型石油灌区集中了大量危险化学品，一旦操作不当，便可能引发火灾、爆炸事故，并造成环境污染等次生灾害。因此，政府和企业对大型石油灌区的安全性和操作人员的专业性提出了很高要求。虚拟现实技术可以构建储罐区应急救援及安全培训系统，它不但能向员工呈现操作流程的各种场景，引导他们学习、掌握安全操作技能，还能模拟事故发生、火光熊熊的场面，让员工在沉浸式虚拟影像中开展救援行动。 VR (Virtual Reality) technology can be widely used in many areas,such as urban planning, interior design, industrial simulation, historic restoration, design of bridges and roads, real estate sales, tourism, education, water power, geological disasters, education and training, and provide practical solutions. In the field of advanced manufacturing, standing in front of large aircraft engines of 3D image, The strengths of virtual -"can be arbitrary tear down" express thoroughly.The operators can put a lot of virtual engine parts one by one, and then into the internal engine.Virtual reality achieves many functions, such as,a cross-platform interactive design, virtual display, virtual assembly, and CAE data visualization capabilities, so it increase the team's design efficiency drastically, and researchers can find the corrected design flaws and potential process problems timely and improve product development manufacturing success rate. Virtual reality technology is also very useful in the field of education and training.It creates conditions for the real tests which are not available or difficult to complete the teaching function.When it refers to high-risk or extreme environments, inaccessible or irreversible operation, high cost, high consumption, large or comprehensive training, etc., virtual reality technology can provide reliable, safe and economical experimental projects.G-Magic Virtual Reality Lab of East China University is an example of virtual reality in University Teaching.The lab has a CAVE virtual reality of cave system and college students’design work can be projected onto the walls, ceiling and floor.For example, the student designed a shower room, he can use the system to show it in the laboratory as the same size as the real
小议科技英语翻译技巧
小议科技英语翻译技巧 科技文体崇尚严谨周密，概念准确，逻辑性强，行文简练，重点突出，句式严整，少有变化，常用前置性陈述，即在句中将主要信息尽量前置，通过主语传递主要信息。科技文章文体的特点是：清晰、准确、精练、严密。那末，科技文章的语言结构特色在翻译过程中如何处理，这是进行英汉科技翻译时需要探讨的问题。现分述如下： 一、大量使用名词化结构 大量使用名词化结构（Nominalization）是科技英语的特点之一。因为科技文体要求行文简洁、表达客观、内容确切、信息量大、强调存在的事实。而非某一行为。 Archimedes first discovered the principle of displacement of water by solid bodies. 阿基米德最先发展固体排水的原理。 句中of displacement of water by solid bodies 系名词化结构，一方面简化了同位语从句，另一方强调displacement 这一事实。 The rotation of the earth on its own axis causes the change from day to night. 地球绕轴自转，引起昼夜的变化。 名词化结构the rotation of the earth on its own axis 使复合句简化成简单句，而且使表达的概念更加确切严密。 If you use firebricks round the walls of the boiler, the heat loss, can be considerably reduced. 炉壁采用耐火砖可大大降低热耗。 科技英语所表述的是客观规律，因之要尽量避免使用第一、二人称；此外，要使主要的信息置于句首。 Television is the transmission and reception of images of moving objects by radio waves. 电视通过无线电波发射和接受活动物体的图象。 名词化结构the transmission and reception of images of moving objects by radio waves 强调客观事实，而"谓语动词则着重其发射和接受的能力。 二、广泛使用被动语句 根据英国利兹大学John Swales 的统计，科技英语中的谓语至少三分之一是被动态。这是因为科技文章侧重叙事推理，强调客观准确。第一、二人称使用过多，会造成主观臆断的印象。因此尽量使用第三人称叙述，采用被动语态，例如：Attention must be paid to the working temperature of the machine.应当注意机器的工作温度。而很少说：You must pay attention to the working temperature of the machine .你们必须注意机器的工作温度。此外，如前所述，科技文章将主要信息前置，放在主语部份。这也是广泛使用被动态的主要原因。试观察并比较下列两段短文的主语。 We can store electrical energy in two metal plates separated by an insulating medium. We call such a device a capacitor, or a condenser, and its ability to store electrical energy capacitance .It is measured in farads. 电能可储存在由一绝缘介质隔开的两块金属极板内。这样的装置称之为电容器，

科技英语翻译的原则_方法及技巧.
翻译是把一种语言里已经表达出来的事物用另一种语言准确流畅地进行重新表达的过程。与其他题材的文章相比,科技专业文章在内容、表达形式和风格上有很大的差别,具有科技性强、专业性强、逻辑严密、表达要求简练的特点,在翻译上力求准确全面、严谨明确和通顺简练。 1科技英语翻译遵循的基本原则 从科技文章的特点来看,大多具有以下几个特征:述说事理、逻辑性强、结构严密、术语繁多,语言严谨、数据精确。这就要求译文必须概念清楚、条理分明、逻辑正确、数据无误,尤其对定义、定律、公式、图表、结论等更应特别注意。科技英语作为特殊英语的一个分支,在词汇构成、遣词造句等方面都有其自身的特点,其语法结构不十分严密、语言习惯和汉语也有不少差别、词汇量大、词语繁多,因此科技英语翻译起来比较困难。另外,科技文章比较重视叙事逻辑上的连贯及表达上的明晰与畅达; 避免行文晦涩,避免表露个人感情,避免论证上的主观随意性。因此,科技英语翻译力求少用或不用描述性形容词以及具有抒情作用的副词、感叹词及疑问词,而是大量使用科技词汇、专业技术用语,译者应尊重客观事实,不能随意改动数据、回避不易翻译的文字,更不能加进自己的主观想象,进行自由翻译。 我国著名翻译家严复提出的“信、达、雅”三准则一直为不少翻译工作者所接受。 “信”指的是译文要忠实于原文,“达”是指译文的通顺达意,“雅”指的是译文的用词修辞。三准则体现了译文和原文信息等值这一基本要领。 “信、达、雅”的翻译准则对各种英语文体的翻译实践都具有指导意义,是衡量一篇译文好坏的标准,也同样适用于科技文献的翻译。由于科技文章特有的文体特征,与其他类文章相比,其“达”和“雅”的内涵不同,它要求在准确传达信息的基础上,使译文更加简洁明快,流畅通顺。2科技英语翻译的基本方法
