科技英语翻译的理解与表达随着世界科技发展的日新月异和我国对外科技交流的日益频繁，科技翻译的重要性越发凸显出来。
科技翻译要求确切理解和掌握原文的内容，不能主观地发挥个人的想法和推测,做到科学性和艺术性的完美结合。
其科学性和艺术性主要体现为“信、达、雅”的翻译标准。
下面就英语科技翻译的科学性和艺术性，以及翻译的三个标准，讨论科技英语翻译的理解与表达。
一、科技翻译的科学性科技英语的翻译由于其文体的特殊性，首先就要求它的译文要求忠于原文，它的文字表达不需要过于华丽的辞藻，语句直截了当，词意简单明了。
而做到这些就需要译者准确理解原文，包括掌握常用词汇的专业化和语句中词汇翻译的灵活性等。
例1：Applications and incomes become the carrier’s focus of attention. Personalized service has present itself as the high mode service.carrier：n.[化学]载体；运送者；带菌者；货架。
这些是“carrier”的常用词意，但是在科技英语翻译中，它更常用其专业释义。
这句句子中的“carrier”如果用常用的几个词意带入，很快就会发现句子是不通顺的，根据前后文则可以猜测它的词意应该与经济体有关。
实际上，这里“carrier”是“运营商”的意思。
译文：运营商的关注焦点已从技术转向了应用、服务和收益。
作为信息服务的高级形态，个性化服务开始逐步走上了前台。
例2：Ozone pollution is a concern during the summer months because strong sunlight and hot weather result in harmful ozone concentrations in the air we breathe.concern：vt.涉及，关系到；使担心。
科技英语翻译1.1翻译的标准第1节翻译练习1The power plant is the heart of a ship.动力装置是船舶的心脏。
The power unit for driving the machines is a50-hp induction motor.驱动这些机器的动力装置是一台50马力的感应电动机。
第1节翻译练习2Semiconductor devices,called transistors,are replacing tubes in many applications.半导体装置也称为晶体管，在许多场合替代电子管。
Cramped conditions means that passengers’legs cannot move around freely.空间狭窄，旅客的两腿就不能自由活动。
All bodies are known to possess weight and occupy space.我们知道，所有的物体都有重量并占据空间。
第1节翻译练习3The removal of minerals from water is called softening.去除水中的矿物质叫做软化。
A typical foliage leaf of a plant belonging to the dicotyledons is composed of two principal parts:blade and petiole.双子叶植物典型的营养叶由两个主要部分组成：叶片和叶柄。
1.2对译者的要求第4节翻译练习1Einstein’s relativity theory is the only one which can explain such phenomena.爱因斯坦的相对论是能解释这种现象的唯一理论。
（直译）All four(outer planets)probably have cores of metals,silicates,and water.这四颗外层行星的内核可能都由金属、硅酸盐和水构成。

参考译文Unit 1课文A石油1油，和煤一样，存在于沉积岩中，而且可能由死去很长时间的生物有机体形成。
含有石油的岩石几乎都来源于海洋，所以形成石油的有机物一定是海洋生物，而不是树木。
2 石油，并不是来自于逐渐积聚的木质物质，而可能是来自于逐渐积聚的海洋生物的脂肪物质。
比如浮游生物：大量浮游在海水表层的单细胞生物。
3 有机物的脂肪物质主要由碳氢原子组成，因此并不需要太多的化学变化就可以形成石油。
生物有机体只需在缺氧的条件下沉积到海湾浅水处的淤泥里。
其脂肪不是分解腐烂，而是逐渐积聚，并在深层的淤泥里圈闭起来，进而经过细微的原子重组，最终形成石油。
4 油比水轻，呈液态，会经由上方覆盖的孔隙性岩石向上渗透，在地球上有些地区到达表层，古人将这些表层石油称为沥青、柏油或异庚烷。
在古代和中世纪，这些石油油苗常被看作药品而不是燃料。
5 当然，表层的油苗数量很少。
而石油油藏上方有时覆盖的是非孔隙性岩石。
石油向上渗透抵达该岩石，然后在岩石下方逐渐积聚形成油层。
若在上方的岩石上钻个孔，石油就可以通过该孔向上迁移。
有时压力过大，石油会向高空喷出。
1859年在宾夕法尼亚州，由埃德温·德雷克成功打出第一口井。
6 如果可以发现一个合适的地点（勘探人员已经识别出地下可能圈闭有石油的地层结构），那么就很容易抽取这一液体燃料，这要比派人到地下把大块的固体煤炭砍成小块要容易得多。
而且一旦获得石油，可以通过地上管道运输，而不必像煤一样，由运货车经过繁重的装卸任务来运输。
7 石油便于抽取，易于运输，促进了石油的应用。
石油可以蒸馏成不同的馏分，每种馏分均由特定大小的分子组成，分子越小，该馏分就越容易蒸发。
8 到19世纪下半叶，最重要的石油馏分是由中等大小的分子构成的煤油，它不易蒸发，被用于照明。
9 然而，到19世纪末人们研制出了内燃机。
内燃机是通过在汽缸里将空气与可燃气体混合，产生爆炸来提供动力的。
最便利的可燃气体是汽油——石油的又一馏分，由小分子构成，容易蒸发。
Types of SustainabilityThe four types of sustainability include human, economic, social, and environmental. All four are required to maintain the entirety of life on Earth. Although interconnected, it is important to note the differences of each in terms of its nature and requirements.Types of Sustainability / HumanThe very basic need of human sustainability is good reproductive health and safe childbearing. Those that reproduce have the responsibility of caring for their children, giving them access to proper education, and promoting their health and wellness. At some point, the children should have enough skills and knowledge such that they can sustain their own way of life. It is at that point that they become considered as productive human capital as well as individuals that can go through the process of reproduction and rearing. As long as this process is maintained at a rate that all human systems can support, human sustainability should be no cause for concern.Types of Sustainability / EconomicIn simple terms, economic sustainability is having a set amount of capital for a certain period. Those who consume that capital must also conserve it so that they will continue to enjoy it towards the end of the specified period. This means that we must preserve all our resources as we consume them so that human beings in the future can enjoy them as well. To achieve this, we must regenerate our resources at a rate that is equal to or faster than our consumption.Types of Sustainability / SocialSocial capital is an important aspect of sustainability because it is through communities and civil societies that humankind can easily and inexpensively work together. Without proper levels of social capital, it can easily deplete and violence as well as mistrust can take over. When that happens, societies and everything else that depends on them will be destroyed. Through proper maintenance of and adherence to laws, rules, and values that societies have developed for the common good, social sustainability can be achieved.Types of Sustainability / EnvironmentalEnvironmental sustainability is important because it involves natural resources that human beings need for economic or manufactured capital. Materials taken from nature are used for solutions that address human needs. If nature is depleted faster than it can regenerate, human beings will be left without raw materials.Furthermore, environmental sustainability also involves ensuring that waste emissions are at volumes that nature can handle. If not, all humans and other living things on Earth can be harmed to the point of extinction.可持续性分类四种可持续性包括人类可持续性，经济可持续性，社会可持续性和环境可持续性。

Unit 1 EnvironmentEarth’s Health in Sharp Decline, Massive Study Finds大规模研究发现：地球的“健康”每况愈下The report card has arrived from the largest ever scientific Earth analysis, and many of the planet’s ecosystems are simply not making the grade.有史以来对地球进行的最大规模的科学分析结果表明，地球上的许多生态系统都达不到标准。
The UN-backed Millennium Ecosystem Assessment Synthesis Report found that nearly two-thirds of Earth’s life-supporting ecosystems, including clean water, pure air, and stable climate, are being degraded by unsustainable use.由联合国主持的《千年生态系统评估综合报告》指出，由于不可持续的使用，地球上将近三分之二的用来维持生命的生态系统（包括干净的水源、纯净的空气以及稳定的气候）正遭受破坏。
Human has caused much of this damage during the past half century. Soaring demand for food, fresh water, timber, fiber and fuel have led to dramatic environmental changes, from deforestation to chemical pollution, the report says. The already grim situation may worsen dramatically during the first half of the 21st century, the report’s authors warn.以上大部分的破坏都是人类在过去的半个世纪里造成的。

科技英语阅读1-8单元译文：Unit 1罗素悖论的提出是基于这样的一个事例：设想有这样一群理发师，他们只给不给自己理发的人理发。
假设其中一个理发师符合上述的条件，不给自己理发；然而按照要求，他必须要给自己理发。
但是在这个集合中没有人会给自己理发。
（如果这样的话，这个理发师必定是给别人理发还要给自己理发）1901年，伯特兰·罗素悖论的发现打击了他其中的一个数学家同事。
在19世纪后期，弗雷格尝试发展一个基本原理以便数学上能使用符号逻辑。
他确立了形式表达式（如：x =2）和数学特性（如偶数）之间的联系。
按照弗雷格理论的发展，我们能自由的用一个特性去定义更多更深远的特性。
1903年，发表在《数学原理》上的罗素悖论从根本上揭示了弗雷格这种集合系统的局限性。
就现在而言，这种类型的集合系统能很好的用俗称集的结构式来描述。
例如，我们可以用x代表整数，通过n 来表示并且n大于3小于7，来表示4，5,6这样一个集合。
这种集合的书写形势就是：x={n：n是整数，3<n<7}。
集合中的对象并不一定是数字。
我们也可让y={x：x是美国的一个男性居民}。
表面上看，似乎任何一个关于x的描述都有一个符合要求的空间。
但是，罗素（和策梅洛一起）发现x={a：a不再a中}导致一个矛盾，就像对一群理发师的描述一样。
x它本身是在x的集合中吗？否定的答案导致了矛盾的出现。
当罗素发现了悖论，弗雷格立即就发现悖论对他的理论有致命的打击。
尽管这样，他还不能解决这个问题,并且上世纪有很多的尝试，去解决这个问题（但没有成功）。
罗素自己对这个悖论的回答促进了类型理论的形成。
他解释说，悖论的问题在于我们混淆了数集和数集的集合。
所以，罗素介绍了对象的分级系统：数、数集、数集的集合等等。
这个系统为形式化数学的形成奠定了基础，至今它还应用于哲学研究和计算机科学分支。
策梅洛对于罗素悖论的解决方法用新的公理：对于任意公式A（x）和任意集合b，都会有一个集合满足y={x：x既在b中又满足A（x）}取代了以前的公理：对于任意公式A（x），都会有一个集合满足y={x：x满足A（x）}。
