科技英语翻译Unit 1—Unit 7
Unit 1 Electronics:Analog and Digital
1.As with series resonance, the greater the resistance in the
circuit the lower the Q and, accordingly, the flatter and broader the resonance curve of either line current or circuit impedance.
对于串联谐振，电路中的电阻愈大Q值就愈低，相应地线路电流或电路阻抗的谐振曲线也就愈平、愈宽。
2.A wire carrying a current looks exactly the same and weighs
exactly the same as it does when it is not carrying a current.
一根带电的导线其外表与重量都与不带电导线完全一样。
3.Click mouse on the waveform and drag it to change the pulse
repetition rate, or directly enter a new value of the period in the provided dialogue box, while keeping the pulse width unchanged.
在波形上点击鼠标并拖动来改变脉冲重复频率，或者在提供的对话框中直接输入新的周期值，而保持脉冲宽度不变。
4.Electronics is the science and the technology of the passage of
charged particles in a gas, in a vacuum, or in a semiconductor.
Please note that particle motion confined within a metal only is not considered electronics.
电子学是一门有关带电粒子在气体、真空或半导体中运动的科学技术。注意，在本书中粒子运动仅限于金属的情况不属于电子学。
5.Hardware technologies have played vital roles in our ability to
use electronic properties to process information, but software and data processing aspects have not developed at the same speed.
硬件技术在我们使用电子特性来处理信息的能力中一直起着重要作用，而软件及数字处理方面却没能与硬件同步发展。
6.However, in a properly designed DC amplifier the effect of
transistor parameter variation, other than Ico, may be practically eliminated if the operation point of each stage is adjusted so that it remains in the linear operation range of the transistor as temperature varies.
然而在设计得当的直流放大器中，若调节每一级的工作点使之在温度变化时保持在晶体管线性区，就能在实际上消除Ico以外的晶体管参数变化所造成的影响。
Unit 2 Integrated Circuits
1.If analog signals are to be transmitted digitally, they first have
to be sampled at a specified rate and further converted to discrete amplitude samples by quantization.
如果要以数字方式传输模拟信号，首先必须以一定的频率对信号进行采样，然后通过量化进一步将它们转换为离散的幅度样本。
2.Linear filters amplify or attenuate selected spatial frequencies,
can achieve such effects as smoothing and sharpening, and usually form the basis of re-sampling and boundary detection algorithms.
线性滤波器放大或衰减选择的空间频率，能够实现像平滑和锐化这些效果，通常是重采样和边缘检测算法的基础。
3.Stability and repeatability are fundamental attributes of digital
circuits, however, and the necessary accuracy can be obtained in a digital version of the modulator by an appropriate choice of word length to represent the signals.
稳定性和可重复性是数字电路的基本性质，不过在数字式调制器中必要的精度可通过适当地选择代表信号的字长而获得。
4.The first observation is made on the fundamental relationship
between the nature of system and the periodicity of its frequency response: a continuous system has an aperiodic frequency response, while a discrete system has a periodic frequency response.
从系统性质和它频率响应的周期性之间的基本关系中首先可以看到：连续系统有非周期性的频率响应，而离散系统有周期性的频率响应。
5.The main function of the receiver is to extract the input
message signal from the degraded version of the transmitted signal coming from the channel.
接收器的主要功能是从由信道传输来的退化了的信号中提取出输入消息。
Unit 3 EM Fields,Antenna and Microwaves
1.A very commonly used method of microwave measurements is
based on the study of a standing wave pattern formed along the line because of the interference of incident and reflected waves.
一个很常用的微波测量方法是基于对驻波图形的研究，这种驻波是由入射波和反射波之间的干涉而沿着传输线形成
的。
https://www.sodocs.net/doc/445177070.html,putations show a reduction of 6dB in the EM field
intensity with the distance doubled, and an increase of 3dB in the intensity with the transmitted power doubled. This result provides verification to the algorithm used.
计算表明，当距离增大一倍时，电磁场强度减小6分贝；
而发射功率增大一倍时，场强则增加3分贝。这一结果验证了所用算法的正确性。
3.Like transfer of heat by conduction, convection and radiation,
microwave heating can be considered as another mode of heat transfer, in which heat is produced directly at the location of the dielectric losses.
就像通过传导、对流、辐射来传递热量一样，微波加热可以看作热传递的另一种方式，即热量直接产生于发生介电损耗的地方。
4.Operation of the radar is based on the measurement of the time
it takes for a pulse transmitted from an antenna to get reflected by the object to be detected and to return at the antenna and the receiver.
雷达的工作是基于对天线发出的脉冲被所要探测的目标反射，（然后）回到天线和接收机所需时间的测量。
5.Other motivations for using CAD in circuit design includes the
wish to acquire confidence in a design that was accomplished by other means, and, not least in importance, a sense of curiosity or perhaps a desire to discover the unexpected.
在电路设计中使用CAD的其它动机包括：想要验证用别的方法设计出来的电路；满足好奇心或者可能是想发现预想不到的现象。后一个动机并非是最不重要的。（取得信心，并非最不重要，意料之外的事）
6.The spacing between the repeating amplifiers is a function of
the cable attenuation and the system bandwidth so that the gain provided by these amplifiers compensates for the loss introduced by the cable.
中继放大器之间的间距是电缆衰减和系统带宽的函数，以便这些放大器提供的增益补偿电缆引起的损耗。
7.When the cut-off frequency is no less than the maximal
frequency of the original signal, nor is it greater than the difference between the sampling frequency and the maximal frequency, the original signal may be completely rebuilt.
当截止频率不小于原始信号的最高频率，也不大于采样频
率和最高频率之差，原始信号可以完整地重建。
8.While the politics of the last one hundred years centered
around Industrial Age technology, the politics of the future will be based on Information Age concerns oriented towards the storage, protection and exchange of information.
尽管近百年来的政治活动是以工业时代的技术为中心的，未来的政治活动将基于信息时代的事物，面向信息的存储、保护和交换。Unit 4 Communication and Information Theory https://www.sodocs.net/doc/445177070.html,munication may be broadly defined as the transfer of
information from one point to another. When the information is to be conveyed over any distance a communication system is usually required. Within a communication system the information transfer is frequently achieved by superimposing or modulating the information on to an electromagnetic wave which acts as a carrier for the information signal. This modulated carrier is then transmitted to the required destination where it is received and the original information signal is obtained by demodulation. Sophisticated techniques have been developed for this process by using electromagnetic carrier waves operating at radio frequencies as well as microwave and millimeter wave frequencies. However, communication may also be achieved by using an electromagnetic carrier that is selected from the optical range of frequencies.
通信可以广义地定义为从一处到另一处的信息传递。当要将信息传输到任何距离以外时就需要有一个通信系统。在通信系统内部，信息的传输经常通过将信息叠加或调制到作为信号载体的电磁波上来实现。经调制的载波然后被传送到要求的目的地，在那里被接收，原始信号通过解调被恢复出来。
为了实现这一过程，已经利用工作在射频、微波以及毫米波频率上的电磁载波开发了复杂的技术。不过通信也可以用光波频段上的电磁载波来实现。
2.Electronic communications is the transfer and movement of
data between locations through the use of computers. An electronic communication system includes the equipment needed to support the movement of information, the communication lines and media to carry the information, the computer software and programs to control the flow of information, the personnel to plan, implement, and operate communications, and the management of all these resources.
Electronic communications establishes links between people as well as computers.
电子通信就是通过使用计算机在不同的地点之间传输数据。
一个电子通信系统包括：支持信息流动所需要的设备，承载信息的通信线路和媒介，控制信息流的计算机软件和程序，计划、实施、操作通信系统的人员，以及对所有这些资源的管理。电子通信建立起人和人、计算机和计算机之间的联系。
3.First generation communications systems can be characterized
by the use of analog transmission techniques, and the use of simple multiplex access techniques such as frequency division multiple access (FDMA). They suffered from a low user capacity, and security problems due to the simple radio interface used. Second generation systems were introduced in the early 1990’s, and all use digital technology. This provide d an increase in the user capacity of around three times, achieved by compressing the voice waveforms before transmission.
Third generation systems are an extension on the complexity of second-generation systems and are to be introduced after the year 2000. The system capacity will be increased to over ten times original first generation systems, achieved by using complex multiplex access techniques such as code division multiplex access (CDMA), or an extension of TDMA, and by improving flexibility of services available.
第一代通信系统以模拟传输技术和简单复用技术如频分复用为特征。这些系统用户容量低，而且因为使用简单的无线电接口而存在安全问题。第二代通信系统于20世纪90年代初开始引入，全部使用数字技术。通过在传输前将话音波形
压缩使得用户容量提高了三倍。第三代通信系统是对第二代系统在复杂性方面的扩展，预计于2000年以后启用。通过使用复杂的复用技术如CDMA或TDMA的扩展，并提高服务的灵活性使得系统容量比原来的第一代系统提高10倍。
4.For each combination of communication (modulation/detection)
type, channel fading model, and diversity type, the average bit error rate (BER) and/or symbol error rate (SER) of the system is obtained and represented by an expression in a form that can readily be evaluated. All cases considered correspond to real practical channels, and in many instances the BER and SER expressions obtained can be evaluated numerically on a hand-held calculator.
对于通信（调制/检测）类型、信道衰落模型、分集类型的每一种组合，得到系统的平均误码率（BER）和符号错误率（SER），并以容易求值的形式表示。所有考虑的相应于实际信道的情况，以及许多情况下得到的BER和SER表达式均可用手持计算器来计算。
5.Modulation is the systematic variation of some attribute of a
carrier waveform such as the amplitude, phase, or frequency in accordance with a function of the message signal. It is used in communication systems for matching signal characteristics to channel characteristics, for reducing noise and interference, for simultaneously transmitting several signals over a single channel, and for overcoming some equipment limitations. A considerable portion of this book is devoted to the study of how modulation schemes are deigned to achieve the above tasks. The success of a communication system depends to a large extent on the modulation.
调制是载波波形的某些属性，例如幅度、相位和频率，根据消息信号的函数有规则的变化。它用于通信系统以使信号特
性匹配信道特性，减少噪声和干扰，在单个信道上同时传输多个信号，并克服某些设备的限制。本书相当大部分内容是研究如何设计调制方案以实现上述任务。一个通信系统的成功很大程度上依赖于调制。
Unit 6 Mobile Communications
https://www.sodocs.net/doc/445177070.html,munication is the transmission of information from one
point to another. This transmission requires the ability to vary signals with time in a manner which is unpredictable to the receiver.
通信就是信息从一点传送到另一点。这种传送要求信号随时间发生的变化不能在接收端预测。
2.It is true of any communication system that the shape and
amplitude of the transmitted signal will be continuously degraded by the introduction of noise, and the attenuation along the transmission path.
传输的信号会不断地被噪声的引入和线路上的衰减所损伤，对任何通信系统都是如此。
3.Since the very beginning, communications systems have
consisted of three major parts, namely, the equipment, the medium, and the protocol. It is still the case today. However, the close link of telecommunications with the computer technology has brought about tremendous changes in communications, from the concepts, to the contents and the methods.
从一开始通信系统就由设备、媒介和协议三个要素组成。至今依然如此。然而电信与计算机技术的紧密联系使得通信从概念到内容和手段都发生了重大的变化。
4.The availability of such a large collection of system
performance curves in a single compilation allows the researcher or system designer to perform trade-off studies among the various communication type/fading channel/diversity combinations so as to determine the
optimum choice in the face of his or her available constraints. 在一本书中提供如此大量的系统性能曲线，使研究者或系统设计者能在各种通信类型、衰落信道、分集组合之间进行比较研究，从而在他或她所面临的限制之下做出最佳的选择。
5.The channel provides the electrical connection between the
information source and the user. The channel can have many different forms such as a microwave radio link over free space,
a pair of wires, or an optical fiber.
信道提供信息源和用户之间的电路联接。信道可以有许多不同的形式，比如自由空间里的微波联接，一对电线，或者一根光纤。
6.The degradation of the transmitted signal is a result of signal
distortion due to imperfect response of the channel and due to undesirable electrical signals (noise) and interference. Noise and signal distortion are two basic problems of electrical communication.
传输信号的退化是信号失真的结果，而这种失真又是由信道的非理想响应及不想要的电信号（噪声）和干扰引起的。噪声和信号畸变是电子通信的两个基本问题。
Unit 8 Optical Communications
1.Early in the twentieth century, it was found that light could cause atoms to emit electrons
and that, when light released an electron from an atom, the energy possessed by the electron very greatly exceeded that which the atom could, according to the electromagnetic wave theory, have received.
在二十世纪早期，人们发现光能够使原子放出电子，而且当光从原子中释放一个电子时，电子所包含的能量大大超过由电磁波理论得到的原子所接收的能量。
2.Pulse broadening determines the minimum separation between adjacent pulses, which in
turn determines the maximum information-carrying capacity of the optical fiber.
脉冲的展宽决定了相邻脉冲之间的最小间隔，这一间隔进而又决定了光纤的最大信息容量。
3.If one were to transmit such information without impressing it on an optical carrier but
instead on a radio frequency (RF) carrier a bit higher than the maximum rate, the transmission wavelength of the RF carrier would be centimeters or larger.
如果传输这样的信息不是将它加载到光纤上，而是加载在略高于最大速率的射频载波上，则此射频载波就会是厘米波或是波长更长一些的波。
4.The smallness of the optical wavelength, therefore, allows for the miniaturization of
transmit and receive modules, which should allow considerable reduction in size, weight, and cost of optical communication systems with respect to microwave/radio wave counterparts.
光波波长之小使发射和接收模块得以小型化，这就使光通信系统的尺寸、重量以至价格与相应的微波、无线电波通信系统相比都大为降低。
5.Although all the advantages of coherent optical communication systems have yet to be
brought to fruition, another property of optical radiation has made today’s optical communication systems not desirable for applications.
虽然相干光通信系统的所有优点还有待于落实在具体成果中，光辐射的另一性质却使目前的光通信系统不利于应用。
6.When coupled with light’s short wavelength which allows for miniature sources and
detectors and micron-sized waveguides, direct detection schemes have allowed for small, lightweight, high bandwidth systems which are competitive in many areas, most notably to the present telecommunications transmission, although a myriad of other applications are continually opening up.
光的波长很小，可以使用小型的光源和检测器以及微米级的波导，于是用直接检测方案可实现在许多领域具有竞争力的小巧的宽带系统，这些领域中特别引人注目的是当前电信传输中的应用，尽管无数其他应用也在不断涌现出来。
7.As mentioned previously, these applications have tended to open up more slowly than
originally predicted, as cost was really not much of a consideration in telecommunications, where equipment costs are swamped by other considerations.
如前所述，（线路）成本并非电信系统中真正重要的考虑因素，通信设备的成本主要受到其他因素的制约，因此这些应用比预料的出现得慢。
8.As wavelengths decrease to approach the size of circuit components, circuit elements are
no longer lumped as such, and leads can act as reflective components and/or antennas and lumped elements as electromagnetic resonators.
随着波长减小到接近于电路元件的尺寸，电路单元就不再是集总的，导线可起到反射元件以及（或）天线的作用，集总单元则成为电磁谐振器。
Unit 17 Computers and Networks
1.For the first time ever the landscape is changing, as high
volume personal computer multimedia applications proliferate.
First affected were monitors, which for some time have offered higher-than-broadcast speed and resolution. One can
expect cameras to follow, with high-speed, high-resolution devices driven by consumer digital still camera technology and lower-resolution, ultra low cost units driven by entertainment, internet conferencing, and perceptual user interface applications.
随着大量个人计算机多媒体应用的急剧增加，情况首次发生了变化。最早受到影响的是显示器，相当长时间以来它已经能够提供比广播级更高的速度和分辨率。人们可期待照相机/摄像机也随之跟上，包括由民用数字照相机所推动的高速度、高分辨率器件，娱乐业、互联网远程会议和用户视觉界
面应用所推动的低分辨率和极低价格的设备。
2.If you already have the fastest CPU in a particular family and
still want more performance, then it may be more cost-effective to add system RAM or cache RAM than to put in a processor from a different family. Adding system memory can bring significant performance increases at a relatively low cost, assuming you configure the memory correctly. In addition to added cache and system RAM, a faster and larger hard drive can save you time when running applications dependent on heavy drive access and data throughput. Adding
a graphics accelerator card can help, too, especially if you are
looking for a way to stay awake while your system redraws images.
如果你已经有了某一系列中最快的CPU而还想要更多的性能，那么增加系统RAM或高速缓存RAM也许比插入一枚另一系列的处理器更合算。假设你正确地配置内存，则增加
系统内存可以较低的代价带来可观的性能提高。除了增加高速缓存和系统RAM，一个更快和更大的硬盘可在运行依赖于大量读写硬盘和有大量数据吞吐时节省你的时间。增加一个图形加速器也是有益的，特别是你在寻找某种途径使你在系统重显图象时能保持“清醒”，则尤其是如此。
3.In university environments, MATLAB has become the
standard instructional tool for introductory courses in applied linear algebra, as well as advanced courses in other areas. In industrial settings, MATLAB is used for research and to solve practical engineering and mathematical problems. Typical uses include general purpose numerical computation, algorithm prototyping, and special purpose problem solving with matrix formulations that arise in disciplines such as automatic control theory, statistics, and digital signal processing (time-series analysis).
在大学环境里，MATLAB已成为应用线性代数导论以及其他领域中许多高级课程的标准教学工具。在工业界，MATLAB被用于研究和解决实际的工程和数学问题。典型的应用包括通用数值计算、算法原型测试以及使用矩阵公式的专门问题的解决，这些问题是在自动控制理论、统计、数字信号处理（时间序列分析）等学科中提出来的。
从科技英语翻译(1)
2007年6月 第8卷 第2期 长沙铁道学院学报(社会科学版) J un.2007 Vol.8 No.2 从文体特征谈科技英语的翻译3 禹智华 (中南大学外国语学院,湖南长沙 410075) 摘 要:每一类体栽的文章都有其独特的语言表现形式和结构规律。本文从文体学角度分析了科技英语在其词汇、句法、语篇等方面的特点及对其翻译方法的探讨。 关键词:文体特征;词汇;句法;语篇;翻译 在21世纪这个高度信息化的时代,科技英语越来越受到人们的重视。但对于大多数人而言,翻译科技英语时只是满足于表面的处理,并未研究真正的科学的语言,只是依据为一般读者编写的百科全书或图书中出现的通俗专业介绍。他们认为,只要懂得语法规则和一些科技词汇,就能够理解并翻译科技英语文章了。于是这样一个公式似乎顺理成章:科技英语=一般英语语法+科技词汇。其实不然科技英语它着重于对客观事物的描述,或者对逻辑概念的推理,因而在词汇、句法、语篇等方面有着与通用英语不同的自身特点,形成了独特的文体风格。从它特点看来,我们不仅要注意语法词汇等语言学的部分,同时更要根据英汉两种语言表达上的差异,进行原语与目标语之间的调整,使翻译作品更加符合译入语读者的思维习惯。 一、词汇特点 科技词汇主要由一般词汇、专业词汇和半专业词汇三部分构成,他们具有如下明显特点: 第一,科技词汇多源于希腊语和拉丁语,具有庄重、正式的语体特征,如pharmaceutical(药品)、circumvent(阻止)、mechanical(机械的)、technology(技术)等词汇。这类词一般词形较长,难于记忆,其有效的手段就是通过英语的构词法来掌握,尤其是派生法。主要特点是通过添加前、后缀构成新词,不少科技词汇均由此产生,如mono(单一)———monoxide (一氧化物)、di(二,双)———diatomic(双原子的)、anti(抗,防)———antiage(防老化的)、super(超)———(天体物理学)、under(低于,次于)———underreaction(反应不充分)。 第二,不少动词短语往往由一些“稳重”的规范动词替代,体现了科技英语精炼、严肃、权威的文体特征,如turn on--complete、use up--consume和exhaust、put up with--tolerate。 第三,同一词语词义的多专业化,即同一个英语常用词不仅被多个专业采用,而且含义也各不相同。例如“order”一词,在日常英语指“命令、订购”等,在军事上指“队形”,在计算机领域指“指令”,在法律上指“法院上的决议”,在数学方面指“阶,次序”,建筑学则指“柱型”。对于这一类词语,只有通过上下文和具体的语言环境才能确定其真正的含义。 第四,广泛使用缩略词。据统计,这类词语大约有2～3万,其构成方式分有三种:(1)将词的部分截缩而构成新词,如parachute———chute(降落伞)、semiconductor———semicon (半导体)、technology———tech(技术);(2)将词组中的每个词的首字母加在一起构成新词,如Unidentified Flying Object ———U FO(不明飞行物)、Liquefied Natural Gas———L N G(液化天燃气);(3)从两个单词中抽出部分字母而构成新词,如rectifier transformer———rectiforlner(整流变压器)、telegram exchange telex(电传)。过程。因此,从各方面提高科技翻译工作者的能力及加强对科技翻译的研究,找出其特色也显得尤为重要。 二、句法特点 11被动句的广泛使用 因为科技文章的主要目的是讲述客观现象,介绍科技成果,说明生产过程等,所以无须指出行为的主体,使用被动句不仅比主动句更少主观色彩,而且可以使读者的注意力集中在叙述的客体上,与日常英语相比,科技英语更倾向于使用被动句。英语被动语态句的处理,不外乎两种方法:一种是仍保留为被动句,另一种是转换成汉语的主动句。下面以一些句子进行举例说明。 例如:The outside of the converter is made of steel plates. 转钢炉的外壳由钢板制成。 Electrons closer to the nucleus are held more tightly than those in the outer orbits. 靠近原子核的电子比外层轨道上的电子结合的紧。 21大量使用名词化结构和非谓语动词形式 这种结构和形式能够把原来的施动结构蕴藏在深层结构里,从而把更多的信息融于一体,使彼此的逻辑关系更严密,表达更精确,这符合科技英语追求语言表达简练、凝重、客观与浓缩的要求。例如下面这句话,科技英语借助非谓语动词形式和名词化结构,只用一个谓语动词就表达了汉语须用几个行为动词才能表达清楚的概念。Applied science,on the other hand is directly concerned with the application of the working laws of pure science to the practical affairs of life and to increasing man’s control over his environment,thus leading to the development of new techniques processes and machines.应用科学则直接涉及应用问题,它研究的是如何将纯科学的工作定律应用于实际生活,应用于加强人类对其周围环境的控制,从而导致新技术、新工艺和新机器的产生。 31长句较多 2713收稿日期:2006-12-16 作者简介:禹智华(1981-),女,湖南邵阳人,硕士研究生。

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

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，

邢骏杰信息工程1班20091309010 We use touch screens everywhere: tourist kiosks, automatic teller machines, point-of-sale terminals, industrial controls. Half a dozen vendors, plus in-house departments at major manufacturers, produced $800 million worth in 2000. The market is growing because the interfaces are easy-to-use, durable and inexpensive. Touch screens employ one of three physics principles for detecting the point of touch. Pressing a “resistive” design with a finger or other stylus raises a voltage. In “capacitive” models, a finger draws a minute current (this method is often used for cursor pads on notebook computers). In other designs, a finger or stylus interrupts a standing pattern of acoustic waves or infrared lights that blanket the surface. Resistive screens are the oldest, most widely used and least expensive, and they work with any stylus (finger, pen). Capacitive screens must be touched by a finger or an electrically grounded stylus to conduct current. Wave screens are the newest and most expensive. Surface acoustic wave screens must be touched by a finger or a soft stylus such as a pencil eraser to absorb energy; infrared screens work with any stylus. The different technologies may be used in the same applications, although pros and cons lead to prevalent combinations: resistive screens for industrial controls and Palm Pilots; capacitive screens for slot machines; wave screens for A TMs and indoor kiosks. Most people are unaware of the type of screen they are using. But tricks can help you tell, according to Frank Shen of Elo TouchSystems in Fremont, Calif., the largest U.S. maker. Push the screen lightly with your fingernail (not your skin). If it responds, it could be resistive or infrared. In this case, place two separated fingers aga inst the screen at the same time. If the cursor moves beneath one finger, the unit is infrared (software registers the first touch); if the cursor moves between the fingers, it is resistive (the points are averaged). If the unit does not respond to your fingernail, again place two separated fingers against it. If the cursor moves beneath one finger, the unit is acoustic wave; if the cursor moves between the fingers, it is capacitive.
