Unit 8 Computer Basics
Text
We can define a computer as a device that accepts input, processes data, stores data, and produces output. According to the mode of processing, computers are either analog or digital. They can be classified as mainframes, minicomputers, workstations, or microcomputers. All else (for example, the age of the machine) being equal, this categorization provides some indication of the computer’s speed, size, cost, and abilities.
Unit 8 Computer Basics
Computer architecture, in computer science, is a general
term referring to the structure of all or part of a computer system. The term also covers the design of system software, such as the operating system (the program that controls the computer), as well as referring to the combination of hardware and basic software that links the machines on a computer network. Thus, computer architecture covers computer systems, microprocessors, circuits, and system programs.
unit8 专业英语的翻译-5：被动句的翻译
科技文章侧重描述和推理，强调客观准 确，所以谓语大量地采用被动语态，以 避免过多的使用第一、第二人称而引起 主观臆断的印象。英语和汉语都有被动 语态，但两种语言在运用和表达上不尽 相同。因此，翻译时必须对被动句做适 当的灵活处理。
被动句的翻译
1、英语中有些着重被动动作的被动句，为突 出其被动意义，可直接译为汉语的被动句，翻 译时最常见的方式是在谓语动词前加“被”。但 过多的使用同一个词会使译文缺乏文采，因而 应根据汉语习惯采用一些其他的方式表达被动 态，如可用：“由”、“给”、“受”、“加以”、 “把”、“使”等。如： The machine tools are controlled by PLC. 机床由可编程控制器控制。
被动句的翻译
The quartz crystal does not vibrate at certain frequency until the voltage is applied. 直到电压加上去以后，石英晶体才会以 某一频率振荡。 Recently some new kinds of steel have been developed in our country. 译：最近，我国研制出一些新钢。
被动句的翻译
People’s life has been improved greatly in recent years.
译：近年来人们的生活得到很大改善。
被动句的翻译
有些原句中没有行为主体，翻译时可增加适当 的主语使译文通顺流畅，如“人们”、“有人”、 “大家”、“我们”等。如： A few years ago it was thought unbelievable that the computer could have so high speed as well so small volume. 几年前人们还认为计算机具有如此高的运行速 度和如此小的体积是一件难以置信的事。

New Words and Expressions
coal-fired a. 燃煤的 furnace n. 炉，炉膛，燃烧室 pulverizer n. 磨煤机，粉煤机 preheated a. 预热的 boiler n. 锅炉，蒸发器，蒸汽发生器 flue gas 烟气，废气，排烟 electrostatic a. 静电的 precipitator n. 除尘器
Section 1 Coal-Fired Power Plants
the intermediate-pressure (IP) turbine. Leaving the IP turbine, steam (at lower pressure and much expended) is directed to the low-pressure (LP) turbines. The exhaust steam from the LP turbines is cooled in a condenser, and as feed-water, is reheated (with steam extracted from the turbines) and pumped back to the boiler.
Section 1 Coal-Fired Power Plants
In fossil-fuel power plants, coal, oil, or natural gas is burned in a furnace, the combustion products heat water, converting it to steam, and the steam drives a turbine which is mechanically coupled to an electric power generator. A schematic diagram showing a typical coal-fired power plant is given in Fig.8-1. In very brief outline, the operation of the plant is as follows. Coal is taken from storage and fed to a pulverizer (or a mill), mixed with preheated air, and blown into the furnace, where it is burned. The furnace contains a complex of tubes and drums

Two common applications of local area networks are hardware resource sharing and information resource sharing．Hardware resource sharing allows each personal computer on the network to access and use devices that would be too expensive to provide for each user．[1] Information resource sharing allows anyone using a personal computer on the local area network to access data stored on any other computer in the network．In actual practice ， hardware resource sharing and information resource sharing are often combined．

Electromotive force 电动势
• Any combination of a conductor and of a source of e.m.f which permits electrons to travel round in a continuous stream is called an electric circuit.
[brɑ:ntʃ] 分支 [pɑ:θ] 路径，轨道

• In ordinary house lighting, for instance, lamps are connected in parallel, each lamp filament representing an independent path from the minus ['mainəs] main wire to the plus wire. [plʌs] 正的，正号 负的；负号 • In parallel circuits the total current is equal to the sum of all the currents that are passing through the branches of that of another.
['siəri:z] 系列，连续； 串联
串联电路
['pærəlel] 并行的；平行线
并联电路
• When electrical devices are connected so that the current is not divided at any point, they are said to be connected in series. • The current in every part of this kind of circuit is the same. • As a matter of fact, in everyday electric work we very often deal with circuits where the current branches between two or more paths.
