专业英语重要部分翻译

第一课P3

But when we see that the three classes of modern society, the feudal aristocracy, the bourgeoisie and the proletariat, each have a morality of their own, we can only draw the one conclusion：that men, consciously or unconsciously, derive their ethical ideas in the last resort from the practical relations on which their class position is based--from the economic relations in which they carry on production and exchange.

但是，如果我们看到，现代社会的三个阶级即封建贵族，资产阶级和无产阶级都各有自己特殊的道德，那么我们由此只能得到这样的结论：人们自觉的或不自觉，归根到底总是从他们阶级地位所依据的实际关系中——从他们进行生产和交换的经济关系中，吸取自己的道德观念。

P5道德和法。平等

The idea that all men, as men, have something in common, and that to that extent they are equal, is of course primeval. But the modern demand for equality is something entirely different from that; this consists rather in deducing from that common quality of being human, from that equality of men as men, a claim to equal political and social status for all human beings, or at least for all citizens of a state or all members of a society.

切人，作为人来说，都有某些共同点，在这些共同点所及的范围内，他们是平等的，这样的观念自然是非常古老的。但是现代的平等要求与此完全不同；这种平等要求更应当是从人的这种共同特性中，从人就他们是人而言的这种平等中引伸出这样的要求：一切人，或至少是一个国家的一切公民，或一个社会的一切成员，都应当有平等的政治地位和社会地位。要从这种相对平等的原始观念中得出国家和社会中的平等权利的结论，要使这个结论甚至能够成为某种自然而然的、不言而喻的东西，必然要经过而且确实已经经过了几千年

P11

The idea of equality, both in its bourgeois and in its proletarian form, is therefore itself a historical product, the creation of which required definite historical conditions that in turn themselves presuppose a long previous history. It is therefore anything but an eternal truth. And if today it is taken for granted by the general public —in one sense or another —if, as Marx says, it "already possesses the fixity of a popular prejudice", this is not the effect of its axiomatic truth, but the effect of the general diffusion and the continued appropriateness of the ideas of the eighteenth century.

可见，平等的观念，无论以资产阶级的形式出现，还是以无产阶级的形式出现，本身都是一种历史的产物，这一观念的形成，需要一定的历史条件，而这种历史条件本身又以长期的以往的历史为前提。所以，这样的平等观念说它是什么都行，就不能说是永恒的真理。如果它现在对广大公众来说——在这种或那种意义上——是不言而喻的，如果它像马克思所说的，“已经成为国民的牢固的成见”那么这不是由于它具有公理式的真理性，而是由于18 世纪的思想得到普遍传播和仍然合乎时宜。

第二课，苏格拉底回忆录4段P24

He said that justice, moreover, and all other virtue is wisdom. That is to say, things just, and all things else that are done with virtue, are "beautiful and good"; and neither will those who know these things deliberately choose aught else in their stead, nor will he who lacks the special knowledge of them be able to do them, but even if he makes the attempt he will miss the mark and fail. So the wise alone can perform the things which are "beautiful and good"; they that are unwise cannot, but even if they try they fail. Therefore, since all things just, and generally all things "beautiful and good," are wrought with virtue, it is clear that justice and all other virtue is wisdom.

苏格拉底说：正义和所有其它的一切美德都是智慧。也就是说，正义之事及一切按美德而行的事物都是“美而好的”；知道美德之事人不会有意去选择其他的事物，缺乏美德知识的人则没有能力去做，即使他尝试去做，也会失败。（知行合一）因此，智慧的人能做美而好的事情；而愚昧的人则不能做美而好的事情，尽管他们试着去做，也是注定要失败的。因此，既然所有的正义之事和其他一切美而好的事都是美德，非常明显，正义和所有其它美德都是智慧。

第三课第一段P37

Virtue, then, being of two kinds, intellectual and moral, intellectual virtue in the main owes both its birth and its growth to teaching (for which reason it requires experience and time), while moral virtue comes about as a result of habit, whence also its name (ethike) is one that is formed by a slight variation from the word ethos (habit). From this it is also plain that none of the moral virtues arises in us by nature; for nothing that exists by nature can form a habit contrary to its nature.

德性有两种：理智的和道德的。理智的德性，是由于训练而产生和增长的(所以必需时间和经验)，道德的德性则是习惯的结果；以我们希腊的语言来说，道德的德性这个名字，是由习惯这个名字稍加变化而成。从这一点说，显然，我们没有天赋的道德的德性；因为天赋的东西是不能由于训练而改变的。

第六段P40

But though our present account is of this nature we must give what help we can.First, then, let us consider this, that it is the nature of such things to be destroyed by defect and excess, as we see in the case of strength and of health (for to gain light on things imperceptible we must use the evidence of sensible things); both excessive and defective exercise destroys the strength, and similarly drink or food which is above or below a certain amount destroys the health, while that which is proportionate both produces and increases and preserves it. [pr?'p?:??nit] 虽然如此，但是我们仍必须尽力研究它。我们首先必须注意，过度与不及，均足以败坏德行。这正如体力和健康的情形一样（因为我们只能用可见事物来说明不可感的东西），运动太多或太少，同样有损体力；饮食过度或过少，也会损害健康；惟有适度才可以产生、增进和保持健康。节制，勇敢，及其他德性，也正是这样。一个畏首畏尾、退缩不前、永不能应事的人，可以变为懦夫；同时，一个无所畏惧、敢冒一切危险的人，则会成为莽汉。一个纵情恣乐，毫无节制的人，会变成放荡的人；一个像乡下人一样、忌避一切快乐的人，会变为麻木不仁。所以，过度与不及都有损节制和勇敢，惟适度可以保全之。

第20段（即第五部分）P45

Next we must consider what virtue is. Since things that are found in the soul are of three kinds- passions, faculties, states of character, virtue must be one of these. By passions I mean appetite, anger, fear, confidence, envy, joy, friendly feeling, hatred, longing, emulation, pity, and in general the feelings that are accompanied by pleasure or pain; by faculties the things in virtue of which we are said to be capable of feeling these, e.g. of becoming angry or being pained or feeling pity; by states of character the things in virtue of which we stand well or badly with reference to the passions, e.g. with reference to anger we stand badly if we feel it violently or too weakly, and well if we feel it moderately; and similarly with reference to the other passions

其次，我们必须研究德性是什么？在灵魂里可以看到三类东西：情感，官能，习惯或品性，德性必是这三者之一。所谓情感，是指嗜欲，忿怒，恐惧，自信，嫉妒，喜悦，友情，憎恨，渴望，好胜心，怜悯心，和一般伴随痛苦或快乐的各种感情；所谓官能，是指使我们能获得感情的东西，例如，我们借我们的官能，方能发怒、感觉痛苦、起怜悯心等；习惯或品性是指我们借以调摄我们的情感变好或变坏的东西，例如我们竟至于暴怒，或应怒而不怒，这是调摄得坏的结果，

但是若怒而适得其当，这就是调摄得好。至于其他的情感，可以类推

第七部分P50

We must, however, not only make this general statement, but also apply it to the individual facts。For among statements about conduct those which are general apply more widely, but those which are particular are more genuine, since conduct has to do with individual cases, and our statements must harmonize with the facts in these cases. We may take these cases from our table.

（关于德性和过恶）只作这样的一般叙述，是不够的。我们必须进一步把这种一般的理论用到特殊的实例(即若干种德性与过恶)上去。关于行为，一般的叙述嫌广泛，不如特殊的叙述表达得较真切。行为总是与特殊事件相关，所以我们的一般叙述，也必须能用到特殊事件上，才算有效。那么，我们从下面的表里，取出这些特殊的例子来加以论列。

第四课第一段P77

The next good quality belonging to a gentleman, is good breeding. There are two sorts of ill-breeding: the one a sheepish bashfulness, and the other a mis-becoming negligence and disrespect in our carriage; both which are avoided by duly observing this one rule, not to think meanly of ourselves, and not to think meanly of others.

一个绅士的第二种美德是良好的礼仪，礼仪不良有两种;第一种是忸怩羞怯，第二种是行为不检点和轻慢;要避免这两种情形就只有好好的遵守下面这条规则，就是不要看不起自己，也不用看不起别人。

P83 section145

Though the managing ourselves well in this part of our behaviour has the name of

good-breeding, as if peculiarly the effect of education; yet, as I have said, young children

should not be much perplexed about it; I mean, about putting off their hats, and making legs modishly. Teach them humility, and to be good-natur'd, if you can, and this sort of manners will not be wanting; civility being in truth nothing but a care not to shew any slighting or

contempt of any one in conversation.

虽然我们在这些方面做得好就叫做有教养，好像是教育的特有的效果似的，但是我也说过，年轻的儿童不应该因他多受烦扰，我的意思是指他们的时派地脱帽和退步致敬，如果你能尽力把谦虚和善良的品性交给他们，这种礼貌便不至于缺乏了，其实礼仪不过是一种小心，不在交往中对任何人表示任何轻视和侮蔑而已。

In the case of a resistor, the voltage-current relationship is given by Ohm’s law, which states that the voltage across the resistor is equal to the current through the resistor multiplied by the value of the resistance. 就电阻来说, 电压—电流的关系由欧姆定律决定。欧姆定律指出:电阻两端的 电压等于电阻上流过的电流乘以电阻值。 2]It may be that the inductor voltage rather than the current is the variable of interest in the circuit. 或许在电路中,人们感兴趣的变量是电感电压而不是电感电流。 Viewed in this light, it will be found that the analysis of three-phase circuits is little more difficult than that of single-phase circuits. 这样看来,三相电路的分析比单相电路的分析难不了多少。 At unity power factor, the power in a single-phase circuit is zero twice each cycle. 在功率因数为 1时,单相电路里的功率值每个周波有两次为零。 It should be noted that if the polarity of point Awith respect to N ( is assumed for the positive half-cycle, then when used in the same phasor diagram should be drawn opposite to, or 180? out of phase with, . 应该注意,如果把 A 点相对于 N 的极性(定为正半周,那么在用于同一相量图中时就应该画得同相反,即相位差为 180? One problem with electronic devices corresponding to the generalized amplifiers is that the gains, AU or AI, depend upon internal properties of the two-port system. 对应于像广义放大器这样的电子装置,一个问题就是增益 AU 或者 AI ,它们取决于两输入端系统的内部特性。

Chapter 1 Passage 1 Human Body In this passage you will learn: 1. Classification of organ systems 2. Structure and function of each organ system 3. Associated medical terms To 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。本文描绘并阐述了各系统的主要部分。 The skeletal system is made of bones, joints between bones, and cartilage. Its function is to provide support and protection for the soft tissues and the organs of the body and to provide points of attachment for the muscles that move the body. There are 206 bones in the human skeleton. They have various shapes - long, short, cube - shaped, flat, and irregular. Many of the long bones have an interior space that is filled with bone marrow, where blood cells are made. 骨骼系统由骨、关节以及软骨组成。它对软组织及人体器官起到支持和保护作用，并牵动骨胳肌，引起各种运动。人体有206根骨头。骨形态不一，有长的、短、立方的、扁的及不规则的。许多长骨里有一个内层间隙，里面充填着骨髓，这即是血细胞的制造场所。 A joint is where bones are joined together. The connection can be so close that no movement is possible, as is the case in the skull. Other kinds of joints permit movement: either back and forth in one plane - as with the hinge joint of the elbow - or movement around a single axis - as with the pivot joint that permits the head to rotate. A wide range of movement is possible when the ball - shaped end of one bone fits into a socket at the end of another bone, as they do in the shoulder and hip joints. 关节把骨与骨连接起来。颅骨不能运动，是由于骨与骨之间的连接太紧密。但其它的关节可允许活动，如一个平面上的前后屈伸运动，如肘关节；或是绕轴心旋转运动，如枢轴点允许头部转动。如果一根骨的球形末端插入另一根骨的臼槽里，大辐度的运动（如肩关节、髋关节）即成为可能。 Cartilage is a more flexible material than bone. It serves as a protective, cushioning layer where bones come together. It also connects the ribs to the breastbone and provides a structural base for the nose and the external ear. An infant's skeleton is made of cartilage that is gradually replaced by bone as the infant grows into an adult. 软骨是一种比一般骨更具韧性的物质。它是骨连结的保护、缓冲层。它把肋骨与胸骨连结起来，也是鼻腔与内耳的结构基础。一个婴儿的骨骼就是由软骨组成，然后不断生长、

Historical Development of Matertials and Technology The 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 of something's development Example： 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。

United 1 材料科学与工程 材料在我们的文化中比我们认识到的还要根深蒂固。如交通、房子、衣物，通讯、娱乐和食物的生产，实际上，我们日常生活中的每一部分都或多或少地受到材料的影响。历史上社会的发展、先进与那些能满足社会需要的材料的生产及操作能力密切相关。实际上，早期的文明就以材料的发展程度来命名，如石器时代，铜器时代。早期人们能得到的只有一些很有限的天然材料，如石头、木材、粘土等。渐渐地，他们通过技术来生产优于自然材料的新材料，这些新材料包括陶器和金属。进一步地，人们发现材料的性质可以通过加热或加入其他物质来改变。在这点上，材料的应用完全是一个选择的过程。也就是说，在一系列非常有限的材料中，根据材料的优点选择一种最适合某种应用的材料。直到最近，科学家才终于了解材料的结构要素与其特性之间的关系。这个大约是过去的 60 年中获得的认识使得材料的性质研究成为时髦。因此，成千上万的材料通过其特殊的性质得以发展来满足我们现代及复杂的社会需要。很多使我们生活舒适的技术的发展与适宜材料的获得密切相关。一种材料的先进程度通常是一种技术进步的先兆。比如，没有便宜的钢制品或其他替代品就没有汽车。在现代，复杂的电子器件取决于所谓的半导体零件. 材料科学与工程有时把材料科学与工程细分成材料科学和材料工程学科是有用的。严格地说，材料科学涉及材料到研究材料的结构和性质的关系。相反，材料工程是根据材料的结构和性质的关系来设计或操纵材料的结构以求制造出一系列可预定的性质。从功能方面来说，材料科学家的作用是发展或合成新的材料，而材料工程师是利用已有的材料创造新的产品或体系，和/或发展材料加工新技术。多数材料专业的本科毕业生被同时训练成材料科学家和材料工程师。“structure”一词是个模糊的术语值得解释。简单地说，材料的结构通常与其内在成分的排列有关。原子内的结构包括介于单个原子间的电子和原子核的相互作用。在原子水平上，结构包括原子或分子与其他相关的原子或分子的组织。在更大的结构领域上，其包括大的原子团，这些原子团通常聚集在一起，称为“微观”结构，意思是可以使用某种显微镜直接观察得到的结构。最后，结构单元可以通过肉眼看到的称为宏观结构。 “Property”一词的概念值得详细阐述。在使用中，所有材料对外部的刺激都表现出某种反应。比如，材料受到力作用会引起形变，或者抛光金属表面会反射光。材料的特征取决于其对外部刺激的反应程度。通常，材料的性质与其形状及大小无关。实际上，所有固体材料的重要性质可以概括分为六类：机械、电学、热学、磁学、光学和腐蚀性。对于每一种性质，其都有一种对特定刺激引起反应的能 力。如机械性能与施加压力引起的形变有关，包括弹性和强度。对于电性能，如电导性和介电系数，特定的刺激物是电场。固体的热学行为则可用热容和热导率来表示。磁学性质

Fashion,which is as old as time and as new as tomorrow,is one of the most powerful forces in our lives .It influences what we wear,the way we talk,the foods we eat,the way we live,how and where we travel,what we travel,what we look at,and what we listen to.Fashion is what lead us todiscard a product that is still useful but is no longer ―in‖.It is also what makes us sometimes wear more clothes than we may actually need,and sometimes less than is needed to product us from the ccold or the sun. 流行是这样一种事物，是我们抛弃了还可以使用，但不再时髦的产品。有时候使我们穿比我们真正穿的衣服多，有时候比我们穿抵御严寒酷暑的少。 If there is one absolute constant pertaining to fashion,it is the fact that it is always changing-sometimes rapidly,sometimes slowly,but it is never static or dormant.This element of change is recognized in the definitions of fashion itself cited earlier,by the use of such words as ―prevailing‖or ―a given period of time.‖To ignore the element of change is like looking at a still photograph in place of a motion picture.The still tells you what is happening here and now ;the motion picture shows you what came before and what may lie ahead. 如果存在着一种符合流行的绝对永恒，那就是流行是永远变化着的这一事实，（这种变化）时快时慢，但绝不会固定下来或呈休止状态。 “Fashion is a social phenomenon which reflects the same continuing change that rides through any given age .‖Change in fashion ,he emphasized,‘correspond with the subtle and often hidden network of forces that operate on society……’ “流行是一种社会现象，它反映了任何特定年代同样都要经历的持续变化。‖他强调说：“流行变迁与那些作用于社会的影响力量所具有的微妙，而又常常是暗藏着的系统是一致的。”It is only in restrospect that fashion changes seem marked or sudden .Autually ,they come about as a result of a series of gradual shifts from one season to the next.For example ,when women’s skirts began inching up from midcalf in the 1960s,this gradual shortening was not particularly noticeable at first .It was only when skirts moved thigh-high,in the form of minis and micro-minis ,that people took notice of the approaching extreme.Similarly,when men begin to abandon ultrannarrow ties and suit lapels in favor of more and more width,the changs are not noticed at first. 只有当追溯过去的时候，流行的变迁才显得特别引人注目或突然，实际上，这些变迁的发生是从一个季节到另一个季节的一系列逐渐变化的结果。例如，女裙的逐渐变短的时候并没有被注意到，。 ………………………………………………………… Color can be the basis for a whole group or line .It is the first element to which consumers respond .People relate personally to color,usually either selecting or rejecting a garment beccause of its ccolor appeal.Therefore,designers must cconsider their customers and provide colors that are both appealing and flattering. 色彩是整个款式系列中的基本要素，它是能够引起顾客回应的第一要素。人们把色彩和个人联系起来，他们往往根据颜色来选择或拒绝一件衣服，因此设计师必须考虑他们的顾客，并且提供出令他们喜爱和满意的色彩，消费群体。 In clothing,neutrals such as beige,tan,brown,white ,gray,and black are even more popular than the ccolors just mentioned.The reason is probably that they present a pleasing background for the wearer without completing for attention. Neutrals are part of every season‖s fashion picture ,as either a strong fashion statement or a way to round out a color story. 在服装中，中色调例如灰中色，深褐，褐色，白灰和黑色，甚至还有比刚刚提到的更多的

1.2 总线互连 总线是连接两个或多个设备的通信通路。总线的关键特征是，它是一条共享传输介质。多个设备连接到总线上，任一个设备发出的信号可以为其他所有连接到总线上的设备所接收。如果两个设备同时传送，它们的信号将会重叠，引起混淆。因此，一次只能有一个设备成功地（利用总线）发送数据。 典型的情况是，总线由多条通信通路或线路组成，每条线(路)能够传送代表二进制1和0的信号。一段时间里，一条线能传送一串二进制数字。总线的几条线放在一起能同时并行传送二进制数字。例如, 一个8位的数据能在8条总线线上传送。 计算机系统包含有多种不同的总线，它们在计算机系统层次结构的各个层次提供部件之间的通路。连接主要计算机部件(处理机, 存储器, I/O)的总线称为系统总线。系统总线通常由50~100条分立的(导)线组成。每条线被赋予一个特定的含义或功能。虽然有许多不同的总线设计，但任何总线上的线都可以分成三个功能组：数据线、地址线和控制线。此外可能还有为连接的模块提供电源的电源线。 数据线提供系统模块间传送数据的路径，这些线组合在一起称为数据总线。典型的数据总线包含8、16或32根线，线的数量称为数据总线的宽度。因为每条线每次传送1位，所以线的数目决定了每次能同时传送多少位。数据总线的宽度是决定系统总体性能的关键因素。 地址线用于指定数据总线上数据的来源和去向。例如，如果处理机希望从存储器中读一个字的数据，它将所需要字的地址放在地址线上。显然，地址总线的宽度决定了系统最大可能的存储器容量。 控制线用来控制对数据线和地址线的访问和使用。由于数据线和地址线被所有部件共享，因此必须用一种方法来控制它们的使用。控制信号在系统模块之间传送命令和定时信息。定时信息指定了数据和地址信息的有效性，命令信号指定了要执行的操作。 大多数计算机系统使用多总线，这些总线通常设计成层次结构。图1.3显示了一个典型的高性能体系结构。一条局部总线把处理机连接到高速缓存控制器，而高速缓存控制器又连接到支持主存储器的系统总线上。高速缓存控制器集成到连接高速总线的桥中。这一总线支持连接到：高速LAN、视频和图形工作站控制器，以及包括SCSI 和FireWire的局部外设总线的接口控制器。低速设备仍然由分开的扩充总线支持，用一个接口来缓冲该扩充总线和高速总线之间的通信流量。 PCI 外部设备互连是流行的高带宽的、独立于处理机的总线，它能够作为中间层或外围设备总线。当前的标准允许在66MHz频率下使用多达64根数据线，其原始传输速率为528MB/s, 或4.224Gbps。PCI被设计成支持各种各样基于微处理机的配置，包括单处理机和多处理机的系统。因此，它提供了一组通用的功能。PCI使用同步时序以及集中式仲裁方案。 在多处理机系统中，一个或多个PCI配置可通过桥接器连接到处理机的系统总线上。系统总线只支持处理机/高速缓存单元、主存储器以及PCI桥接器。使用桥接器使得PCI独立于处理机速度，又提供快速接收和传送数据的能力。 2.1 光存储介质：高密度存储器 2.1.1 光盘 光盘技术最终可能使磁盘和磁带存储淘汰。用这种技术，磁存储器所用的读/写头被两束激光代替。一束激光通过在光盘上刻制微小的凹点，对记录表面进行写；而另一束激光用来从光敏感的记录表面读取数据。由于光束容易被偏转到光盘上所需要的位置，所以不需要存取臂。 对用户而言，光盘正成为最有吸引力的选择。它们(光盘)对环境变化不太敏感，并且它们以每兆字节比磁盘低得多的存储器价格提供更多的直接存取存储器。光盘技术仍在出现，并且还需要稳定；然而，目前有三种主要类型的光盘。它们是CD-ROM、WORM盘和磁光盘。 CD-ROM 1980年引入的，非常成功的CD，或紧密盘是设计来提高音乐的录音重放质量的光盘。为了制作一张CD，把音乐的模拟声音转换成等价的数字声音，并且存储在一张4.72英寸的光盘上。在每张光盘上可以用数字格式（用20亿数字位）记录74分钟的音乐。因为它的巨大存储容量，计算机工业的企业家们立刻认
