专业英语第八章课文翻译1
Chiguo Chapter 8 Section 1 Coal-Fired Power Plants燃煤发电站第一段：在化石燃料发电厂中，煤，石油或者天然气在燃烧室中燃烧，燃烧产生高温的水，然后转换成水蒸气，高温的水蒸气将驱动汽轮机，汽轮机与发电机机械地连接在一起。
图8.1展示了一个典型的图表示意图。
发电厂的运行用一下简洁的语言概述。
从仓库取出煤块放入粉煤机（或者磨粉机）中粉碎，然后与预热的空气混合，最后充入燃烧室中燃烧。
燃烧室包含一个复杂的管道，抽上的水灌输到一个叫锅炉的设备中，锅炉里面水的温度逐渐上升直至它们成为水蒸气。
水蒸气被送至汽轮机中，与此同时，燃烧的废气（烟道气体）通过物理和静电除尘装置除掉99%以上的固体颗粒（灰尘）在通过烟囱或烟囱体排放出去之前。
第二段：刚刚描述的单元，是输入煤粉，空气和水输出水蒸气的单元，这几个方面的系统被统称为蒸汽发电机组，或燃烧室，或者蒸汽发生器。
当考虑根据是燃烧过程的时候常用“燃烧室”这个术语，同时当考虑因素是水汽循环时，“蒸汽发生器”这个术语被更频繁的使用。
水蒸气的3500磅/平方英寸的典型气压和华氏零下1050度的条件，是通过控制和停止（关闭）汽轮机阀门来提供的。
整齐的热能转化为水轮机的机械能。
从排气机中排出的蒸汽在热交换器中成为冷凝器中冷却形成水，再次被泵抽回锅炉里。
通过调节蒸汽的流量变化来控制涡轮发电机的输出。
截止阀具有保护作用，它通常是完全开放的，但可以“跳闸”关闭，以防止汽轮机发电机组超速，使电力输出突然下贱（由于断路器的行动）和控制阀不关闭。
第三段：图8-1表明的是一个单阶段汽轮机，但在实际中一个更加复杂的多级排列被使用以便能实现相对较高的热效率。
一个典型的多级排列如图8-2所示。
它包括四个有着不同蒸汽气压的汽轮机机械地耦合串联在一起。
用常规的概述就是高压蒸汽来自锅炉然后进入高压汽轮机。
在之前离开高压汽轮机的水蒸气回到锅炉（再热器）地区，然后送往中压汽轮机。

1.These parts can be grouped into four major categories; body, engine, chassis and electrical system.2.The internal combustion engine is most common; this obtains its power by burning a liquid fuel inside the engine cylinder.3.The chassis includes the power train, steering, suspension, and braking systems.4. A power train can include a clutch for manual transmission or a torque converter for automatic transmission, a transmission, a drive shaft, final driveand differential gears and driving axles.5.Basic types are: leaf springs, coil springs and torsion bars.6. A basic ignition system consists of the battery, low-lension cables, the ignition coil, distributor, coil high-tension cable, spark plug cables and sparkplugs.7.The operating strokes are: induction stroke, compression stroke, power stroke, exhaust stroke.8.The major parts of engine are engine block, engine heads, pistons, connecting rods, crankshaft and valves.9.These systems are the fuel system, intake system, ignition system, cooling system, lubrication system and exhaust system.10.The dry clutch mechanism includes three basic parts: driving member, driven member and operating members.11.The spur gears are mounted on four shafts: primary shaft (input shaft), layshaft (countershaft), mainshaft, and reverse idler shaft.12.The three types of braking systems are in use today: service braking system, parking braking system and additional retarding-braking system.13.It has five basic parts: the receiver, expansion valve, evaporator, compressor, and condenser.14.The three normally adjustable angles are caster, camber, and toe.段落一．Elements of the Power TrainThe elements of the power train must meet the following requirements;1)enable driving away,2)convert torque and speed,3)enable different directions of rotation for driving forward and backward,4)transmit tractive and pushing forces,5)permit different rotational speeds of the drive wheels when cornering,6)guarantee optimum operation of the engine (or electric motor ) in terms of fuel consumption and exhaust emissions.Standstill, driving-away and power interruption are made possible by operation the clutch .During driving away, the clutch slips and bridges the difference in rotational speed between engine and power train. When different operating conditions call for a shift of gear, the clutch separates the power train during shifting.Engine torque and engine speed are converted in the transmission in accordance with the tractive-power demand of the vehicle. The transmission design is influenced by the position of the engine and driven axle. Overall conversion takes place usually in a manually shifted transmission with variable transmission ratios and in a final drive with a constant transmission ratio. Nowadays, positive-locking transmissions with toothed gears as the most important elements are of even greater significance than non-positive friction-type transmissions.Two types of toothed-gear transmission are predominant: spur-gear transmissions of the countershaft type as manually shifted transmissions, and planetary-gear transmissions as power-shift transmissions. In addition, transmissions permit the different directions of rotation required for driving forward and backward.Final drive turns the drive through 90°and reduces the speed of the drive by a set amount to the vehicle.The differential provides for the equalization of the different axle and wheel speeds when cornering and for uniform distribution of the drive torque.二.The Hydrodynamic Coupling1. Hydrodynamic CouplingConventionally, the hydrodynamic coupling, also known as the Fötttinger coupling, has an impeller and a turbine wheel with vanes that usually extend in the radial direction. The impeller is often expanded to form a housing which surrounds the turbine. Since, due to the absence of an inner ring, there is no possibility of diverting the oil flow, the turbine torque is equal to the pump torque;公式Therefore 公式The index number depends on the design, the vane angle and the degree of filling of the coupling. The main working area of an hydrodynamic coupling is at v=0.9.2. Hydrodynamic ConverterThe hydrodynamic converter, also known as the Trilok or Fötttinger converter, is capable of operating in two phases: with torque increase in the first phase, and as a hydrodynamic coupling in the second phase. The usual design has three impellers:1) The pump, which is connected to the engine, acts like a centrifugal pump to produce the flow energy of a fluid.2) The turbine, which is connected to the transmission input, converts the flow energy back into mechanical energy.3) The reactor between turbine and pump diverts the flow of the fluid.Thus, the torque output is higher than the pump torque input from the engine. The torque increaseμμ=Mt/Mp is all the higher, the greater the speed difference (slip）between the pump and turbine. Withυ=0, i.e. with the turbine braked to a standstill (stall point, drive-away point), torque conversion reaches its maximum value and falls virtually linearly with rising turbine speed to a torque ratio of 1:1 at the coupling point. Above the coupling point, the reactor, which is supported on the housing by a one-way clutch, runs, torque-free, in the flow. Thus, the converter is now a clutch without torque conversion.For automobiles, the vane geometries are such that, at the drive-away point, the maximum torque increase μA is between 2 and 2.5. The hydraulic efficiencyηhydr=υμis similar in the conversion range to the speed ratioμand reaches values around 97% at high speed.Fluid couplings form the input element of automatic transmissions (in conjunction with planetary-gear trains, clutches, brakes and one-way clutches) and also of manually shifted transmissions in the form converter and clutch unit.三．Constant-mesh TransmissionFig.3-6 illustrates the flow of torque through a typical constant-mesh transmission. This type uses helical or double helical gears which are always in mesh. The mainshaft gear wheels are mounted on bearings and when a gear is required the mainshaft gear is locked to the shaft by a dog clutch.Although the mechanical efficiency is lower the helical gears are quieter and any damage resulting from a bad gear change occurs to the dog teeth instead of the actual gear teeth.元素的力量训练动力传动的要素必须符合下列要求;1)使开车逃走,2)把转矩和速度,3)使不同方向的旋转带动向前和向后,四)推进传送叶轮力量,5)允许不同转速时的驱动轮转弯时,六)保证了优化运行的引擎(或电机)从油耗和尾气排放。

第一课谷歌上过互联网的人都见过谷歌，许多人要在互联网上查找某方面的信息时，他们都会去“谷歌”一下。
作为全世界最有名的互联网搜索引擎，谷歌是网络业界功成名就的最好范例之一。
谷歌始于1996年1月斯坦福大学博士生拉里?佩奇的一个研究项目。
为了找到一种能帮助网络用户搜索到相关网页的更好方法，佩奇设想可以通过检索网页之间的关系来实现。
他认为其他网页链接最多的那些网页一定是最受欢迎的，这项技术结果看起来是成功的。
佩奇和他的合作伙伴谢尔盖?布林于1998年9月7日创建了自己的公司，并在之后的一周注册了这一网址。
这个搜索引擎很快声名鹊起，2000年谷歌开始在自己的网站出售广告。
在投资者的热情资助下，经过几年的发展，谷歌上市了，谷歌的很多雇员一夜之间成了百万富翁。
谷歌最近收购了互联网最大的视频共享网站，而且每天都在不断增加一些新功能，如工具栏、邮件和广告。
当然，成长与成功也带来了竞争。
微软最近就试图收购雅虎以便能在互联网搜索引擎领域与谷歌抗衡。
随着公司的壮大与知名度的提高，谷歌在美国公司就业吸引力的排名也上升到第一。
他们尝试打破传统的办公室设计，努力把办公室变成员工感觉舒适、并能充分发挥自己才华的地方。
现在，谷歌已拥有YouTube、Blogger和其他一些热门网站，并且成为网络广告收入方面的领头羊。
当初两个学生的一个小点子已发展成为一家拥有十亿美元资产的大公司，谷歌也成为全球最著名的商标之一。
谷歌的发展史为当今的网络企业家树立了一个完美的典范，也提供了灵感。

Fuel Supply System of Gasoline EngineAll the gasoline engines have substantially identical fuel systems and run on a mixture consisting of fuel vapor and air. The fuel system comprises the units designed to store, clear and deliver fuel, the units intended to clean air and a unit for preparing a mixture from fuel vapor and air.In a fuel system different components are used to supply fuel from the fuel tank into the engine cylinder. Some of the important components are fuel tank, fuel pump, fuel filter, carburetor, intake manifold and fuellines or tubes connecting the tank, pump and the carburetor.The fuel tank is a fuel container used for storing fuel. It is made of sheet metal. It is attached to the vehicle frame with metal traps and is located at the rear of the vehicle. They are mounted in a boot or boot-floor pan in case of front-engined cars and small commercial vehicles. In order to strengthen the tank as well as to prevent surging of fuel when the vehicle rounds a curve of suddenly stops, baffle plates are attached to the inside of the tank.A cap is used to close the filler opening of the tank. The fuel line is attached at or near the bottom of the tank with a filtering element placed at the connection. The other components of the fuel tank are the fuel gauge sending unit, a vent pipe, receiving unit. To prevent the dirt and water from entering the luggage compartment, a sealing strip is fitted between the fuel tank and boot floor pan. Moreover to limit the transmission of frame distortion to the tank giving rise to squeaking as the metal parts get rubbed together, rubber or felt pads are often fitted between the mountings and the tank. Provision is also made against drumming of the tank by these mountings. The tank may be placed at the side of the chassis frame for convenience in case of large commercial vehicles. The length of the connecting lines or tubes from the tank to the carburetor is also restricted by this at the same time.A porous filter is attached to the outlet lines. By drawing fuel from the tank through the filter, any water in the bottom of the tank as well as any dirt into the fuel gathers on the surface of the filter. To keep the fuel always under atmospheric pressure, the filter pipe or tank is vented.In order to prevent dirt in the fuel from entering the fuel pump or carburetor, fuel filters and screens are used in the fuel system. If the dirt is not removed from the fuel, the normal operation of these units will be prevented. The engine performance will also be reduced.The filter is either fitted inside the fuel tank and pump or operates as a separate unit connected between the fuel tank and pump or between pump and carburetor into the fuel lines. Carburetors are also provided filter screens while a filter element is provided in the fuel tank.The fuel filter used is generally a sediment bowl made of glass or metal and a strainer screen. When the fuel drawn from the tank passes through the filter (through the bowl and strainer screen), particles of dirt and water settle in the bottom of the bowl. In certain vehicles, a separate filter either of the disk or ceramic type is used. It is either located between the fuel pump and carburetor or in the fuel line.For connecting the fuel tank to the fuel pump, metallic tubes or synthetic rubber hose used are called fuel lines. They are usually positioned with metallic clips along the frame side members. The tubing or fuel lines are also used to connect fuel pump to the carburetor. In order to absorb vibration as well as prevent breakage of the fuel lines, a short flexible line is used between the fuel pump and the tank.In order to meter and caution the driver of the motor vehicle about the quantity of fuel consumed and left in the tank, a fuel gauge is used. It is generally fitted on dash board for easy reading of the fuel. It is usually a balancing coil type having construction similar to that of an oil gauge. It is generally electrically operated.It consists of a sending unit mounted on the fuel tank and a receiving unit having a caliberated gauge mounted on the instrument panel.A sending unit consists of a float controlled thermostat or variable resistor. With a float and the float arm extending into the fuel tank, the whole unit is mounted on it. The level of fuel in the tank varies the position of the float. The amount of electrical resistance within the variable resistor for controlling the amount of current sent to receiving unit on the instrument panel is determined by the float position.The receiving unit mounted on the dash board indicates the amount of fuel in the tank on a caliberated gauge by the amount of current received from the sending unit.On modern automobiles, two types of fuel gauges; thermostatic type and an electromagnetic type are used.In order to prevent the rapid wear and tear of engine operating components causing reduced performance air cleaner is fitted to the carburetor air intake, it is mounted on thecarburetor air-horn for trapping dirt. Before entering the carburetor, the air must pass through it.To reduce the noise produced by the air rushing into the carburetor, a silencing chamber is built into the air cleaner. In case the engine misfires back through the carburetor, it acts as the flame arrestor.There are in general three types of the air cleaners used in modern automobiles. They are (a) oil bath cleaner (b) oil-wetted mesh air cleaner (c) dry type air cleaner. The first two are also known as heavy duty air cleaner while the third is known as light duty air cleaner.Fuel pumps are the devices used to supply fuel from the fuel tank to the carburetor. There are in general two main types of fuel pumps used in automobiles. They are main types of fuel pumps used in automobiles. They are (a) mechanical fuel pump (b) electric fuel pump.汽油发动机的燃料供给系统所有的汽油发动机具有基本相同的燃料系统和运行的燃料蒸气和空气组成的混合物中。

Types of Automobiles(UNITTWO)汽车的类型The automobile industry is a fast developing industry. Form the later 18th century when the first automobile was put on road, this industry has developed tremendously. Now there are thousands of factories all over the world manufacturing numerous types of automobiles. This industry employs crores of men and women directly and indirectly in allied industries. The automobile engines are also being used in engine powered machines for agriculture, construction and manufacturing processes. Various types of small engines are also being used in lawn movers, power saws, snow removers and similar equipment. The automobile industry is a developing and demanding industry which does not find its end or saturation point. There is a great demand for varied types of automotive products, vehicles and engines. There is also a great demand for trained and experienced persons in this industry for diagnosing motor vehicle troubles, repairing and replacing engines components, transmissions, propeller shafts, differentials, axles, steering system components, brake system components, suspension components, air conditioners, heaters, body and glass work.汽车产业是一个迅速发展的行业。
形成后18世纪当第一汽车被放在路,这个行业的发展极大。
现在有成千上万的工厂世界各地制造许多类型的汽车。
这个行业雇佣了卢比的男性和女性直接和间接地在盟军的产业。
汽车引擎也被用于发动机动力机器为农业、建筑业和制造业的过程。
各种类型的小引擎也被用于草坪搬家公司,电锯,雪消毒剂和类似的设备。
汽车行业是一个发展中国家和要求行业没有找到它的结尾或饱和点。

一般有三种主要分类的各种类型的车辆。
The single-unit vehicles or load carriers.车辆的单件或负载运营商。
Articulated vehicles.铰接车辆。
The heavy tractor vehicles.沉重的拖拉机车辆。
Single-unit vehicles are of conventional four-wheel type. The great majority of vehicles are of two axle design, In these vehicles the front axle is a steering non-driving axle and the rear axle is the driving axle. With the passage of time, a great many changes have taken place in the number of axles and the driving arrangements.单一制车辆四轮类型的传统。
绝大多数的车辆被两个轴的设计,在这些车辆前轴是转向非驱动轴和后轴驱动轴。
随着时间的流逝,许多变化已经发生轴的数量和驾驶的安排。
In this classification, digital terms like 4×2, 4×4, 6×4etc,are commonly used. The first figure denotes the total number of wheels and the second figure the number of driving wheels.在这个分类、数字术语像4×2、4×4、6×4等,被普遍使用。
第一个图表示轮子的总数和第二个图驱动轮的数量。
A lower powered three-wheeler with a single steering wheel in front and a conventional rear driving axle is an example of articulated vehicles. It has a greater handing ability in awkward places. It can be turned about its own tail due to the three-wheel construction. The coupling mechanism between semi-tailer and tractor in most of these vehicles is arranged for automatic connection and coupling up necessitating only its reversing into the position. But for uncoupling operation, a lever is provided within the driver‟s cabin to reverse the whole process. A pair of retractable wheels in front are also provided. Along with the coupling or uncoupling operation, they can be raised or lowered automatically.一个低功率的三轮车和一个方向盘在前面,一个传统的后方驱动轴是一个例子,铰接车辆。
它有一个更大的将在尴尬的地方的能力。
它可以被关于自己的尾巴由于三轮建设。
之间的耦合机理半挂车和拖拉机在大多数这些车辆安排自动连接和耦合起来只需要其扭转到位置。
但对于解偶联操作,一个杠杆是司机的机舱内提供扭转整个过程。
一双有可以伸缩的轮子还提供前面。
随着耦合或解偶联操作,它们可以自动上调或下调。
To move heavy loads, heavy tractor or independent tractor vehicles commonly operate in pair either in tandem or as …puller‟ and …pusher‟. A special consideration is made in respect of the drive to the front wheels in all-wheel-drive vehicles. We know that the front wheels are to travel farther than the rear wheels on every band. The wind-up produced by this difference of travel over-stresses the transmission system. To avoid this a great necessity of some form of differential or its equivalent has been felt to provide it the front and rear drives. It has been seen that if the conditions are not very abnormal, sufficient amount of tyre slip taking place under running conditions would release these stresses completely.移动重物,沉重的拖拉机或独立的拖拉机车辆操作对无论是在通常为“收割机”串联或和“推进器”。
一个特殊的考虑事项是在尊重的前轮驱动的车辆四轮驱动。
我们知道,前轮是旅行的距离比后轮在每个频带。
这种差异产生的发条的旅行在强调传动系统。
为了避免这一伟大的必要性,某种形式的微分或其等效一直觉得提供它的前方和后方驱动器。
它已经看到,如果条件不太正常,足够数量的轮胎滑发生在运行情况将完全释放这些压力。
An all-wheel drive is better than the introduction of differentials between the various axles. It provides adhesion under the worst possible conditions. On the other hand, the drive to all the other axles is liable to be lost if any one axle or group of axles loses adhesion.一个全轮驱动比引入各种轴之间的差异。
