The positive charge of a proton is similar to the negative charge of an electron. However, a positive charge is the opposite of a negative charge. These charges are called electrostatic charges. Each charged particle is surrounded by an electrostatic field.质子和电子部件的原子构成一切事物在我们的世界。
正电荷的质子是类似于负电荷的电子。
然而,一个正电荷的反面是一个负电荷。
这些指控被称为静电荷。
每个带电粒子周围是一个静电场。
The effect that electrostatic charges have on each other is very important. They either repel (move away) or attract (come together) each other. It is said that like charges repel and unlike charges attract.这个效应,静电指控对方是非常重要的。

Unit 1Reading A The Human complex— A Never –failing Source of Wonderment(人类的复杂性——一个永远不会失去惊叹的话题)“ In my view, ” wrote Thomas Jefferson in 1814 , “no knowledge can be more satisfactory to a man that of his own frame, its parts, their functions and action s. ” Distinguished thinkers before and since Jefferson have held this belief, but curiously, it is not one that the average person wholeheartedly shares.Man’s attitude toward his own body—his single most precious possession—is decidedly ambivalent. At one and the same time he is fascinated by it and fearful of it, partly in echo of ancient taboos, partly in the conviction that the body is too complicated to understand.( “在我看来，”托马斯杰佛逊于1814年写道：“对人来说，没有什么知识会比了解自身的架构、部件、功能和作用更能使他满足。
”包括杰佛逊在内的杰出思想家均持有这个观点，但有趣的是，这个观点并不为普罗大众所由衷地接受。
人们对自己的身体，这个对他自身来说最为宝贵的财富，态度其实是充满矛盾的。

第一单元Human bodyTo understand the human body it is necessary to understand how its parts are put together and how they function. The study of the body's structure is called anatomy; the study of the body's function is known as physiology. Other studies of human body include biology, cytology, embryology, histology, endocrinology, hematology, immunology, psychology etc.了解人体各部分的组成及其功能，对于认识人体是必需的。
研究人体结构的科学叫解剖学；研究人体功能的科学叫生理学。
其他研究人体的科学包括生物学、细胞学、胚胎学、组织学、内分泌学、血液学、遗传学、免疫学、心理学等等。
Anatomists find it useful to divide the human body into ten systems, that is, the skeletal system, the muscular system, the circulatory system, the respiratory system, the digestive system, the urinary system, the endocrine system, the nervous system, the reproductive system and the skin. The principal parts of each of these systems are described in this article.解剖学家发现把整个人体分成骨骼、肌肉、循环、呼吸、消化、泌尿、内分泌、神经、生殖系统以及感觉器官的做法是很有帮助的。

Historical Development of Matertials and TechnologyThe common engineering materials include metals, cementing materials, concrete building stones, clay products, insulating materials, timber. Some of them are described here from the stand-point of occurrence, manufacture, properties, methods of testing, and use.The development of materials with improved properties is a vital phase of engineering. Progress in engineering construction has been dependent on the availability of materials of suitable physical properties in large quantities; for example, the development of the modern automobile was critically dependent on availability of high quality alloy steels, and the all-metal airplane was made possible by the development of light weight high-strength alloys.◆Phase: 相；阶段。
◆a distinct period or stage in a process of change or forming part ofsomething's developmentExample：phase two of the development is in progress.◆第二阶段开发正在进行中。

It shelters us from the elements and provides a place to live, work, and play. Initial responses fron architects and engineers to that early crisis were to explore such alternative energy sources as active and passive solar heating systems. Years of experimentation followed until the premise of that direction was questioned. Instead of replacing the energy source, why not reduce the need for it ? That questioned to the development of what were called super insulated homes, some of which required as little as 5% of the energy used by conventional homes at the time. But initial applications of this technology suffered serious problems with moisture generated from normal household activities and resulted in s focus on indoor air quality. That focus evolved beyond moisture and resulting biological contaminants to gradually include radon and other soil gases , volatile organic compounds, and combustion pollutants. 房子的基本作用没有改变自人类住在山洞里。

Charge and CurrentThe concept of electric charge is the underlying principle for explaining all electrical phenomena. Also, the most basic quantity in an electric circuit is the electric charge. Charge is an electrical property of the atomic particles of which matter consists, measured in coulombs (C).电荷和电流电荷的概念是用来解释所有电气现象的基本概念。
也即，电路中最基本的量是电荷。
电荷是构成物质的原子微粒的电气属性，它是以库仑为单位来度量的。
We know from elementary physics that all matter is made of fundamental building blocks known as atoms and that each atom consists of electrons, protons, and neutrons. We also know that the charge e on an electron is negative and equal in magnitude to 1.60210×10 19C, while a proton carries a positive charge of the same magnitude as the electron. The presence of equal numbers of protons and electrons leaves an atom neutrally charged.我们从基础物理得知一切物质是由被称为原子的基本构造部分组成的，并且每个原子是由电子，质子和中子组成的。

TEM-8 翻译部分英语专业八级翻译真题（1998年——2007年）第一部分汉译英Passage 1.( 1998年)1997年2月24日我们代表下榻日月潭中信大饭店，送走了最后一批客人，已是次日凌晨3点了。
我躺在床上久久不能入睡，披衣走到窗前，往外看去，只见四周群峦叠翠，湖面波光粼粼。
望着台湾这仅有的景色如画的天然湖泊，我想了许多，许多……这次到台湾访问交流，虽然行程匆匆，但是，看了不少地方，访了旧友，交了新知，大家走到一起，谈论的一个重要话题就是中华民族在21世纪的强盛。
虽然祖国大陆、台湾的青年生活在不同的社会环境中，有着各自不同的生活经历，但大家的内心都深国统一大业的早日完成。
世纪之交的宝贵机遇和巨大挑战把青年推到了历史的前台。
跨世纪青年一代应该用什么样的姿态迎接充满希望的新世纪，这是我们必须回答的问题。
日月潭水波不兴，仿佛与我一同在思索……Passage 2.( 1999年)加拿大的温哥华1986年刚刚度过百岁生日，但城市的发展令世界瞩目。
以港立市，以港兴市，是许多港口城市生存发展的道路。
经过百年开发建设，有着天然不冻良港的温哥华，成为举世闻名的港口城市，同亚洲、大洋洲、欧洲、拉丁美洲均有定期班轮，年货物吞吐量达到8，000万吨，全市就业人口中有三分之一从事贸易与运输行业。
温哥华（Vancouver）的辉煌是温哥华人智慧和勤奋的结晶，其中包括多民族的贡献。
加拿大地广人稀，国土面积比中国还大，人口却不足3000万。
吸收外来移民，是加拿大长期奉行的国策。
可以说，加拿大除了印第安人外，无一不是外来移民，不同的只是时间长短而已。
温哥华则更是世界上屈指可数的多民族城市。
现今180万温哥华居民中，有一半不是在本地出生的，每4个居民中就有一个是亚洲人。
而25万华人对温哥华的经济转型起着决定性的作用。
他们其中有一半是近5年才来到温哥华地区的，使温哥华成为亚洲以外最大的中国人聚居地。
Passage 3.( 2000年)中国科技馆的诞生来之不易。
关于经济管理专业英语第四版部分翻译
第一部分 PART 1 MICROECONOMICS第一篇The Concept of Utility 效用的概念经济学家最开始研究消费者行为学是在一个多世纪前当心理学界流行一种说法：人们的很多行为可以解释为人们为了尽可能获得更多的幸福、规避更多的痛苦而做的努力。
这种苦乐心跳很快便被经济学家借用了并运用于消费者的消费行为中并使之成为解释消费者行为的第一个系统理论：基础的经济论点是理智的消费者会有意识的管理他们对于商品和服务的消费来时总体满意度最大。
经济学家把人们对商品和服务的需求与满足称为“效用”。
效用的概念侧重于拥有、使用、消费商品与服务或者从中获益相关的快乐和满足。
是商品固有的效用而且不管商品具有什么样的质量它都有满足幸福感的能力。
效用的来源和引发效用的原因是多种多样的，提一下最主要的：更加健康的身体、富有美感的外观和设计、简单的使用方法、风格和品位、耐用性、方便性、奢华度、舒适度、个性、快乐、威信、地位自尊、安全、自我满足还有权力。
因此效用既有客观特征又有主观特征尤其跟个人品味、偏好、感觉、个性的构成及思维的状态有关。
总的来说，商品拥有的或可识别的效用是可变的，并不是绝对的。
首先，对于同一件商品两个人不会拥有同样程度的满足感，一个人可能通过吸烟获得巨大的效用然而另外的人却觉得很讨厌；凯迪拉克对某些人而言可以说是重要的地位象征（因此获得巨大的效用），然而对已其他人却只有很少或几乎没有效用。
不同的人买同样一件商品的用途和目的有很大的不同。
以花生为例，有的人买了后放在鸡尾酒晚会上油的人买来做花生糖，还有人买来喂松鼠，有几种不同的情形就有几种不同的效用，而且一种商品产生的效用也会随着时间的不同而不同。
汽油价格的上升，很快的调整了人们对小型汽车的效用的看法，羊毛衣的效用或说需求满足的动力对于段冬气候下的人和长冬气候下的人而言就不一样。
不同的人队商品和服务的看法不同，如果这些因素都不考虑的话，对于人们买什么或卖多少，效用的概念提供了以个有意义的根据来解释人们的这种偏好。

大学英语综合教程4Unit 1Text A人在自然界|亚历山大·斯伯金Nature nurtures mankind unselfishly with its rich resources. Yet, man is so carried away in his transformation of nature that he is unaware that it also has limitations and needs constant care. Now worn by the excessive demands of mankind, nature is unable to maintain the ecological balance needed. Humanity is faced with the problem of how to stop, or at least to moderate, the destruction of Mother Nature.人类生活在大自然的王国里。
他们时刻被大自然所包围并与之相互影响。
人类呼吸的空气、喝下的水和摄入的食物，无一不令人类时刻感知到大自然的影响。
我们与大自然血肉相连，离开大自然，我们将无法生存。
Human beings live in the realm of nature. They are constantly surrounded by it and interact with it. Man is constantly aware of the influence of nature in the form of the air he breathes, the water he drinks, and the food he eats. We are connected with nature by "blood" ties and we cannot live outside nature.人类不仅生活在大自然之中，同时也在改变着大自然。

在试验中，他用了一直径63.1厘米的旧自行车轮。
他在车轮接触地面的轮胎上做了标记，而且将车轮向前转动20次。
接下来，他测量了车轮经过的距离，是39.69米。
他用3969除20*63.7得到了数π的近似值3.115384615。
当然，这只是对数π的估计值，并且他也意识到不是很准确。

Primitive by today' s standards, it contained a mere 2, 300 transistors and performed about 60, 000 calculations in a second. Today, the microprocessor is the most complex mass- produced product ever, with millions of transistors performing hundreds of millions of calculations each second.1971年11月，英特尔公司推出了世界上第一台商用微处理器,代号4004，由三位因特尔工程师发明。

Unit1 chemistry and chemists一、英译汉：化学是什么呢？给化学下个定义，就是对物质及其性质的研究。
给物质下个定义，就是所有有重量、占据一定空间体积的东西。
这些定义是能让人接受的，但是并没有解释一个人为什么要懂化学。
这个问题的答案是，我们生活的世界是化学的世界。
你自己的身体就是一个复杂的化学工厂：用化学过程使你所吃的食物和呼吸的空气变化到骨骼、肌肉、血液和组织，甚至你每天所用的能量。
如果疾病阻止这些过程的某个部分发挥正常功能，医生就会开一些化学类的药物，这些药物要么是从自然界中分离的，要么是化学家从化学实验室合成的。
如果没有化学，我们的生活将无法想象，因为化学就在我们身边发挥作用。
想想如果没有化学生活将会变成什么样子——我们家里将没有塑料、电、用来保护的涂料。
将没有合成纤维使我们有衣穿，没有化肥使我们有足够的食物吃。
因为汽车、轮船和飞机没有金属、橡胶和燃料，我们也不能旅行。
没有电话、收音机、电视和计算机，我们的生活将发生很大变化，所有这些产品都靠化学来生产其中的部件。
因为没有药物治疗疾病，人的寿命也将会变短。
化学处在科学研究的前沿，我们喜欢这个迅速发展的技术，你可以为此做出自己的贡献。
看看最近的几个科技研究：计算机图形学能使我们预知小分子能否与大分子结合或反应，这个足以给治疗疾病的药物带来场新的革命；化学家也正在研究运用化学试剂来获得太阳能并使海水淡化的方法；因为金属易腐蚀，化学家也正在研究使用新型的陶瓷材料代替金属的可能性。
在生物技术帮助下，我们发展了食品的新来源、产生燃料的新方法、以及新的丝绸补救方法。
因为计算机帮助我们预知和解释从试管得到的结果，结果的速度、准确性、质量得到迅速提高，所有这些给产品发展带来益处。
化学家应该给我们提供新材料伴随我们进入新世纪。
从事这项学科，你能为社会做出积极的贡献。
这儿有一些选择化学作为职业的好理由。
首先，如果你对化学有兴趣，你可以有机会给新技术的发展做出贡献。

第一章第一篇sectiongTwo variables u(t) and i(t) are the most basic concepts in an electric circuit, they characterize the various relationships in an electric circuitu(t)和i(t)这两个变量是电路中最基本的两个变量，它们刻划了电路的各种关系。
Charge and CurrentThe concept of electric charge is the underlying principle for explaining all electrical phenomena. Also, the most basic quantity in an electric circuit is the electric charge. Charge is an electrical property of the atomic particles of which matter consists, measured in coulombs (C).电荷和电流电荷的概念是用来解释所有电气现象的基本概念。
也即，电路中最基本的量是电荷。
电荷是构成物质的原子微粒的电气属性，它是以库仑为单位来度量的。
We know from elementary physics that all matter is made of fundamental building blocks known as atoms and that each atom consists of electrons, protons, and neutrons. We also know that the charge e on an electron is negative and equal in magnitude to 1.60210×10 19C, while a proton carries a positive charge of the same magnitude as the electron. The presence of equal numbers of protons and electrons leaves an atom neutrally charged.我们从基础物理得知一切物质是由被称为原子的基本构造部分组成的，并且每个原子是由电子，质子和中子组成的。
Unit1课文译文
Unit 1Text A 胜过金钱的报酬我14岁时，夏天给人家修剪草坪挣点钱。
记住那些我不能砍掉的花，那些有意插在地里的东西，或丢失在草地里的东西，我开始了解各种各样的人。
我还通过人们所喜欢的支付方式——按工付酬、按月付酬或者干脆什么都不付，对住在肯塔基州路易斯维尔的邻居们有了些了解。
巴卢先生属于最后一种人，而且他总有自己的理由。
有时，他身上只有50元以上的大票子，有时却身无分文，有时，我敲他家门时，他干脆就不在家。
不过，如果不提钱，他倒是一个好老头，老远见到我，他总是挥挥他的帽子或轻抬帽沿跟我打招呼。
我想他可能只有微薄的退休金，或者他曾受过伤而不能干院里的杂活。
我记住不断加上去的总账，不过也不太在乎这笔钱一共有多少，无非是除草而已，而且巴卢先生园子里的草就那么一点，也花不了多少时间去修整。
七月中旬的一个傍晚，我走过他家，他示意我进去。
厅里很阴凉，也挺暗的，足足过了好一会儿我才适应昏暗的光线。
“我还欠你钱呢”巴卢先生开了腔，“不过……”我想还是让他省了找借口的麻烦吧，“没关系的，不用担心。
”。
“银行把我的账目搞错了”，他又说，没有理睬我的话。
“过上一两天，就可以搞清楚了。
同时，我想你也许可以挑上一两本书，权当付首付款吧。
”他向四面墙壁指了指，我看到屋里到处都堆着书，像个图书馆，只是放得太乱了，没有条理。
“慢慢看吧，”巴卢先生用鼓励的口气说。
“看也行，借也行，或者留着。
挑一些你喜欢的。
你平时看些什么书?”“我不知道。
”我确实不知道。
我通常读一些从杂货店平装书架上弄来的书，或是在家里找到的杂志、麦片盒背面印的东西或报上的连环画。
有意识地专门找某一本书，这想法对我来说倒挺新鲜，倒也不无吸引力，所以我就浏览了一遍那一堆堆的书，问道：“这些书你真的都看过？”巴卢先生点点头，“这只是我要收藏的，值得看第二遍的书。
”“那你给我挑吧。
”他扬了扬眉，把脑袋抬了抬，好像要给我量衣服一样从上到下把我打量了一遍。
过了一会儿，他从一堆书中找出一本递给我，封面是深红色的，挺厚的一本书。

Historical Development of Matertials and TechnologyThe common engineering materials include metals, cementing materials, concrete building stones, clay products, insulating materials, timber. Some of them are described here from the stand-point of occurrence, manufacture, properties, methods of testing, and use.The development of materials with improved properties is a vital phase of engineering. Progress in engineering construction has been dependent on the availability of materials of suitable physical properties in large quantities; for example, the development of the modern automobile was critically dependent on availability of high quality alloy steels, and the all-metal airplane was made possible by the development of light weight high-strength alloys.◆Phase: 相；阶段。
◆a distinct period or stage in a process of change or forming part ofsomething's developmentExample：phase two of the development is in progress.◆第二阶段开发正在进行中。
◆Vital: 必要的，必不可少的。
◆it is vital that the system is regularly maintained.这个系统有必要经常维修。
翻译：常用工程材料包括金属、胶合材料、混凝土建筑石料、粘土产品、绝缘材料、木料。
对其中的一些在这儿从出现、制造、性质、检验方法和用途等方面加以描述。
具有改进性能材料的发展是工程上一个至关重要的发展过程。
工程建筑上的进步一直以来依赖于具有合适物理特性材料的大量供应，例如，现代汽车工业严重依赖于高品质的合金钢的可用性，而轻质高强度合金的发展使全金属飞机的成为可能。
It can be said that "The history of materials is the history of man". Of course, the reverse can be stated:"The history of man is the history of materials". It is said that "New materials are a prerequisite for new technologies". Again the reverse is true. Furthermore, it is true that technology influences man and vice versa. From this viewpoint the question of pre-eminence among the three partners, man, materials and technology is an intellectual game: a controversy of the chicken and the egg type.reverse 相反，相对。
文中作名词用“the reverse can be stated…..”Example: This materi al didn’t resist to the heat, quite the reverse.恰恰相反，这种材料根本就不耐热。
除做名词外，还可以做动词和形容词用。
做动词：the ship's engines reversed and cut out altogether.船上的发动机出现反转，然后就全停了。
做形容词：the trend appears to be going in the reverse direction.趋势似乎正在向反方向发展。
◆prerequisite 首要的，必备的，先决条件◆prerequisite for (to) … 的前提或…的先决条件:◆Training is a prerequisite for competence. 接受训练是掌握技能的前提。
◆Recognition is a prerequisite to understanding.◆认识是理解的前提。
◆pre-eminence 超群，优秀、卓越◆文中，”question of pre-eminence”译为：优先性命题。
◆Furthermore, it is true that technology influences man and viceversa.另外，技术的确影响着人类，反之亦然。
vice versa:相反，反之亦然adv.解释：with the main items in the preceding statement the other way round 反过来也一样，反之亦然e.g. science must be at the service of man, and not vice versa.科学必须为人类服务，反之并非这样。
◆From this view point the question of pre-eminence among the threepartners, man, materials, and technology, is an intellectual game: a controversy of the chicken and the egg type.◆从这一观点可见，人类、材料和技术三者之间谁先谁后的问题是一个智力游戏，是个象鸡和蛋之类的引起争论的问题。
（即到底是先有鸡然后有蛋，还是先有蛋然后有鸡这一类问题，人类、材料和技术三者谁为先，谁为后，就像鸡和蛋何者为先一样，所以说这一问题是一个智力游戏。
）The earth's population has been continuously multiplying since early man first appeared about two million years B.C. The population grew by a factor of 100 about 500,000 years, from 100,000 to 10 million, and this was reached about 4000 B.C. Despite natural catastrophes, plagures, and decimating wars, by 1820 the population had grown again by a factor of 100 to 1 billion people, this time in less than 6000 years. Today there are about 5 billion people and the doubling rate is only about 33 years. Accordingly, it is possible that in not quite 200 years' time there will already be 100 billion (109) people on Earth.◆翻译：◆自从人类在大约公元前两百万年前出现在地球上以来，地球上的人类一直在不停地成倍增长。
在大约50万年内，人类人口的数量增加了100倍，从10万到1千万，这一千万的人口大约是在公元前4000年达到的。
尽管受到了自然灾害、瘟疫和大规模杀戮战争，到1820年，人口总数又增加了100倍，达到了10亿，这次是在不到6000年的时间内完成的。
现在地球上的人口约有50亿，而翻倍的速度大约仅需要33年。
因此，可能在不到200年的时间内，地球上的人口会达到1千亿（109）。
◆catastrophe大灾害，灾祸。
◆an environmental catastrophe.环境大灾难。
◆Plague 瘟疫，祸患（文中做名词用）◆做动词用：折磨，烦扰，打扰。
◆he has been plagued by ill..◆他一直被病魔折磨着◆decimating 杀死大部分的，毁灭大部分的。
The condition for the flourishing of the species Homo Sapiens have improved over time such that man has made the Earth his subject. Through his materials and their uses in technical devices and processes, man has made favorable living conditions which he modifies continually and to which he in turn continuously adapts.Materials are on of our oldest cultural assets. Historical eras are named after the materials that dominated at that time: the Stone Age, the Bronze Age and the Iron Age possibly the end of which we are living through at this time. New materials such as polymers, semiconductors and superconductors, advanced alloys and ceramics, the amorphous metals, and increasingly the composite materials, are appearing on the scene and providing an impetus for technological developments, often with far-reaching consequences. One can expect the discovery of more materials in the future. Every chemical compound and every alloy is a material that could potentially revolutionize our lives to the extent thatthe first stone tools revolutionized the life the early man. Thus the name for the new era should be chosen carefully and perhaps is best left to the future; a position too close could distort the perspective.翻译：近代人类繁衍兴旺的条件随着时间的推移改善了很多，以至于人类使地球受其支配。
