【分析】

1．本句重点考察两个知识点。一个是乐趣之一，说明此处的乐趣应该用复数，必须是可数名词，因此选择pleasure。另一个是题目中给出的visit，需要谨慎处理，是用做动词还是名词。此处我们给出一个时间状语从句when people visit Shanghai，同时还可使用其他从句进行处理。所以答案是Delicious food is one of the pleasures when people visit Shanghai. 2．本题难度不大，重点是明亮的色彩的表达，可以使用bright colors, 也可以使用bright and vivid colors. 所以答案是Street artists bring bright and vivid colors into older neighborhoods with originality

3．本题考查there be + 定语从句从而构成条件状语从句。另外考察“道歉”用“make apology to sb.”。所以答案是If there is someone to whom you need say sorry in your life, make an apology to him.

4．本题考察what引导的主语从句，以及“be peculiar to”的用法。所以答案是What makes this game peculiar lies in that it teaches kids how to handle the problems in real life.

5．本题主要考固定词组的掌握，为了使用in order that引导出的目的状语从句。另外也考查 preferred school，have…knowledge/ understanding of…，overall，accurate等。所以答案是The applications should be carefully prepared in order that the school you like can have an overall and accurate knowledge of your abilities.

Resistors are used as part of electrical networks and electronic circuits. 电阻器是一个二端口电子元件，电阻是阻止电流流动，通过按比例产生其端子之间的电压降的电流，也就是 说，根据欧姆定律:V = IR。电阻R等于电压降V除以通过电阻的电流I。电阻作为电子网络和电子电路的一部分。 Tran sistor In electro nics, a tran sistor is a semic on ductor device commo nly used to amplify or switch electro nic sig nals . A tran sistor is made of a solid piece of a semic on ductor material , with at least three term in als for connection to an exter nal circuit. A voltage or curre nt applied to one pair of the tran sistor ' s term in als cha nges the curre nt flow ing through ano ther pair of term in als. Because the con trolled curre nt can be much larger tha n the con trolli ng curre nt, the tran sistor provides amplificati on of a sig nal. The tran sistor is the fun dame ntal buildi ng block of moder n electro nic devices, and is used in radio, telepho ne, computer and other electr onic systems. Some tran sistors are packaged in dividually but most are found in in tegrated circuits. 在电子技术中，晶体管是一种，常用来放大或进行开关控制电子信号的半导体器。晶体管是 由一块固体半导体材料制成的，且至少有三个终端与外部电路连接。电压或电流适用于一双 晶体管的终端改变目前流经的另一对终端。因为受控电流可以远大于控制电流，晶体管提供 信号的放大。晶体管是构建现代电子设备的基本单元，并在收音机，电话，计算机和其它电子系统被使用。一些晶体管被单独包装，但大多数都在集成电路中。 Tran sformer A transformer is a device that transfers electrical energy from one circuit to anther through in ductively coupled electrical con ductors .

基本电路 包括电路模型的元素被称为理想的电路元件。一个理想的电路元件是一个实际的电气元件的数学模型，就像一个电池或一个灯泡。重要的是为理想电路元件在电路模型用来表示实际的电气元件的行为可接受程度的准确性。电路分析，本单位的重点，这些工具，然后应用电路。电路分析基础上的数学方法，是用来预测行为的电路模型和其理想的电路元件。一个所期望的行为之间的比较，从设计规范，和预测的行为，形成电路分析，可能会导致电路模型的改进和理想的电路元件。一旦期望和预测的行为是一致的，可以构建物理原型。 物理原型是一个实际的电气系统，修建从实际电器元件。测量技术是用来确定实际的物理系统，定量的行为。实际的行为相比，从设计规范的行为，从电路分析预测的行为。比较可能会导致在物理样机，电路模型，或两者的改进。最终，这个反复的过程，模型，组件和系统的不断完善，可能会产生较准确地符合设计规范的设计，从而满足需要。 从这样的描述，它是明确的，在设计过程中，电路分析中起着一个非常重要的作用。由于电路分析应用电路模型，执业的工程师尝试使用成熟的电路模型，使设计满足在第一次迭代的设计规范。在这个单元，我们使用20至100年已测试通过机型，你可以认为他们是成熟的。能力模型与实际电力系统理想的电路元件，使电路理论的工程师非常有用的。 说理想电路元件的互连可用于定量预测系统的行为，意味着我们可以用数学方程描述的互连。对于数学方程是有用的，我们必须写他们在衡量的数量方面。在电路的情况下，这些数量是电压和电流。电路分析的研究，包括了解其电压和电流和理解上的电压施加的限制，目前互连的理想元素的每一个理想的电路元件的行为电路分析基础上的电压和电流的变量。电压是每单位电荷，电荷分离所造成的断电和SI单位伏V = DW / DQ。电流是电荷的流动速度和具有的安培SI单位（I= DQ/ DT）。理想的基本电路元件是两个终端组成部分，不能细分，也可以在其终端电压和电流的数学描述。被动签署公约涉及元素，当电流通过元素的参考方向是整个元素的参考电压降的方向端子的电压和电流的表达式使用一个积极的迹象。 功率是单位时间内的能量和平等的端电压和电流的乘积;瓦SI单位。权力的代数符号解释如下： 如果P> 0，电源被传递到电路或电路元件。 如果p<0，权力正在从电路或电路元件中提取。 在这一章中介绍的电路元素是电压源，电流源和电阻器。理想电压源保持一个规定的电压，不论当前的设备。理想电流源保持规定的电流不管了整个设备的电压。电压和电流源是独立的，也就是说，不是任何其他电路的电流或电压的影响;或依赖，就是由一些电路中的电流或电压。一个电阻制约了它的电压和电流成正比彼此。有关的比例常数电压和一个电阻值称为其电阻和欧姆测量。 欧姆定律建立相称的电压和电流的电阻。具体来说，V = IR电阻的电流流动，如果在它两端的电压下降，或V=_IR方向，如果在该电阻的电流流是在它两端的电压上升方向。 通过结合对权力的方程，P = VI，欧姆定律，我们可以判断一个电阻吸收的功率：P = I2R= U2/ R 电路节点和封闭路径。节点是一个点，两个或两个以上的电路元件加入。当只有两个元素连接，形成一个节点，他们表示将在系列。一个闭合的路径是通过连接元件追溯到一个循环，起点和终点在同一节点，只有一次每遇到中间节点。 电路是说，要解决时，两端的电压，并在每个元素的电流已经确定。欧姆定律是一个重要的方程，得出这样的解决方案。 在简单的电路结构，欧姆定律是足以解决两端的电压，目前在每一个元素。然而，对于更复杂的互连，我们需要使用两个更为重要的代数关系，被称为基尔霍夫定律，来解决所有的电压和电流。 基尔霍夫电流定律是： 在电路中的任何一个节点电流的代数和等于零。 基尔霍夫电压定律是： 电路中的任何封闭路径上的电压的代数和等于零。 1.2电路分析技术 到目前为止，我们已经分析应用结合欧姆定律基尔霍夫定律电阻电路相对简单。所有的电路，我们可以使用这种方法，但因为他们而变得结构更为复杂，涉及到越来越多的元素，这种直接的方法很快成为累赘。在这一课中，我们介绍两个电路分析的强大的技术援助：在复杂的电路结构的分析节点电压的方法，并网电流的方

1.This electron beam sweeps across each line at a uniform rate，then flies back to scan another line directly below the previous one and so on，until the horizontal lines into which it is desired to break or split the picture have been scanned in the desired sequence． 电子束以均匀的速率扫描每一行，然后飞速返回去扫描下一行，直到把被扫描的图像按所希望的顺序分割成行。 2.The technical possibilities could well exist，therefore，of nation-wide integrated transmission network of high capacity，controlled by computers，interconnected globally by satellite and submarine cable，providing speedy and reliable communications throughout the word 因此，在技术上完全可能实现全国性的集成发送网络。这种网络容量大，由计算机控制，并能通过卫星和海底电缆实现全球互联，提供世界范围的高速、可靠的通信。 3.Transit time is the primary factor which limits the ability of a transistor to operate at high frequency． 渡越时间是限制晶体管高频工作能力的主要因素 4.The intensity of sound is inversely proportional to the square of the distance measured from the source of the sound. 声强与到声源的距离的平方成反比。 5.The attenuation of the filter is nearly constant to within 0.5 dB over the entire frequency band． 该滤波器的衰减近于恒定, 整个频带内的变化在0.5 dB以内。 6.At present, the state of most semiconductor device technology is such that the device design and process technology must be supplemented by screening and inspection procedures, if ultimate device reliability is to be obtained and controlled． 目前, 大多数半导体器件的技术尚未十分完善, 以至若要获得并控制器件最终的可靠性, 就必须辅以筛选和检验, 以弥补设计和工艺技术之不足 7.Bandwidth of transistor amplifiers vary from about 250 MHz in the L band to 1000 MHz in the X band． 晶体管放大器的带宽在L波段约为250 MHz, 在X波段为1000 MHz。 8.The output of the differential amplifier is fed to the circuit’s output stage via an offset-compensation network, which causes the op-amp’s output to center at zero volts. The output stage takes the form of a complementary emitter follower, and provides a low-impedance output. 差动放大级的输出通过一个失调补偿网络与输出级相连, 目的是使运放的输出以0 V为中心。输出级采用互补的射极跟随器的形式以使输出阻抗很低 9.Because of the very high open-loop voltage gain of the op-amp, the output is driven into positive saturation (close to +V) when the sample voltage goes slightly above the reference voltage, and driven into negative saturation (close to-V) when the sample voltage goes slightly below the reference voltage. 由于运放的开环电压增益很高, 当取样电压略高于参考电压时, 输出趋向于正向饱和状态(接近+V)。当取样电压低于参考电压时, 输出趋向于负向饱和状态(接近-V)。 10.If the signal source were direct connected instead of capacitor coupled, there would be a low resistance path from the base to the negative supply line, and this would affect the circuit bias conditions. 如果信号源和电路不是用电容耦合而是直接相连，从基极到负电源线就会一个低阻通路，并且这将影响到电路偏置状态 11.The differential amplifier has a high-impedance (constant-current)“tail”to give it a high input impedance and a high degree of common-mode signal rejection. It also has a high-impedance collector (or drain) load, to give it a large amount of signal-voltage gain (typically about 100 dB). 差动放大极有一个高阻抗的“尾巴”（恒流源）以提供高输入阻抗和对共模信号的深度抑制，同时，它还具有一个高阻抗和集电极或漏极负载以提供高的信号电压增益（典型的数据是100dB). 12.On the other hand, a DC negative-logic system, as in Figure 3.6(b), is one which designates the more negative voltage state of the bit as the 1 level and the more positive as the 0 level. 另一方面, 如图3.6(b)所示, 把比特的较低的电压状态记为1电平, 较高的电压状态记为0电平, 这样的系统称为直流负逻辑系统。 13.For example, to represent the 10 numerals (0, 1, 2, …, 9) and the 26 letters of the English alphabet would require 36 different combinations of 1’s and 0’s. Since 25<36<26, then a minimum of 6 bits per bite are required in order to accommodate all the alphanumeric characters. 例如，要表示0～9十个数字和英文字母表中的26个字母，就需要0和1的36种不同的组合。因为25<36>26,

英文原文： With all the exciting developments in the realm of communications technology over the last few years it would be easy to think that we are living in times of the most astounding transformations. However, the technologies that so many of us are addicted to today mobile phones, the internet, satellite TV are built on the achievements of our endeavors. The history of communication goes back thousands of years. Each new development has transformed the world we live in. An understanding of the journey we have taken to get where we are now shows that today’s techniques are refinements of what came before. Really big revolutions may be still to come. communication begins with the first conversations between people it is believed that language developed through gestures using the hands and bodies, and had evolved into spoken tongues by the time of the great migration of humans from Africa some 100,000 years ago.The first long distance communication must have arisen shortly after conversation, with the discovery that it was possible to make oneself heard from a distance by shouting, or banging objects together to make a sound that travels far. The fire and the smoke it produces may also have been used for simple communication between separated groups. Communication techniques such as shouting and smoke signals allow people to make their mark over a wider area. The recording of information allowed human beings to communicate over great expanses of time. Cave paintings up to 36,500 years old have been found people from that far back are communicating with us today although it is hard to know what they were saying. 5,500 years ago, more systematized alphabets were developed by the Phoenicians. Sumerians and Egyptians. They also developed new ways of storing their information, some of which have survived till today. Scholars have had some success in translating these alphabets and the languages they convey, giving us insight into societies long dead. The realisations that it is possible to communicate through space and time are the two most important communication leaps in history. Everything that has come since has merely improved the efficiency of these two tasks. The next leap was the combination of writing and transmitting information. This begin with people or animals acting as couriers, delivering written messages. The first postal services were in China around 900BC. Human runners and birds were used to transport messages starting in at least 776BC, when the winner of the Olympic games was reported to the Athenians via homing pigeons possible the first journalist reporting back to base from a remote location. With the discovery of electricity the speed and range of communication once again began to increase. In 1793 Claude Chappe invented the Semaphore telegraph line, which allowed reliable

电子信息与通信工程专业外语(张雪英)课文翻译1.4节基础电子学

基础电子学 电子学衍生于对电力的研究和应用，是工程学和应用物理学的领域。电力涉及力的产生，传输与使用金属导体。电子学利用电子不同的运动方式及通过供气材料，如硅与锗等半导体，其他设备如太阳能电池，LED ，微波激射器，激光及微波管等实现。电子学应用于包括广播、雷达、电视、卫星系统传输，导航辅助设备系统，控制系统，空间探测设备，微型设备如电子表，许多电气设备和电脑等方面。 1. 电子学的开端电子学的历史始于20 世纪，包括三个关键元素：真空管，晶体管和集成电路。 19 世纪早期是理论和发明取得重大发展的时代。发现了红外线和紫外线。道尔顿在1808 年提出了原子理论。在1840 年之前就发现了热电效应、电解效应和光电效应。20 年之间相继产生了工作在低压下的放电管，辉光放电，新型电池及早期的扩音器。因此，在1800—1875 年之间，发现了基本的物理现象，电话，留声机，麦克风及扬声器等在实际应用中达到了极致。至于 19 世纪末期，无线电报，磁记录，阴极射线示波器等都被发明了。 20 世纪早期也见证了现代电子技术的开端。1880 年爱迪生发明了白炽灯成为现代电子领域的历史先驱者。他发现有微弱的电流从加热的灯丝流向真空管内附着的金属板。这就是众所周知的“爱迪生效应”。如果使用了一个非电器的热源，注意到电池仅是必要的用来加热灯丝使电子移动。1904 年，约翰利用爱迪生效应发明了二极管，李.德.佛列思特紧接着在1906 年发明了三极管。这些真空管设备使电子能源控制的放大及传输成为可能。20 世纪初真空管的引入使现代电子学快速成长。采用真空管让信号的控制成为可能，这是早期的电报电话电路不可能实现的，也是早期用高压电火花产生无线电波的发射机所不能实现的。 电子管首先应用于无线通信。Guglielmo Marconi 于1896 年开辟了无线电报的发展，于1901 年实现了远距离广播交流。早期的收音机包括了无线电报（摩尔斯电码信号传输）或收音机电话（语音留言）。所有基于二极管和快速的发展都归功于一战期间军队的武力交流。早期的无线电广播发射机，电报机和电话利用高电压火花来产生电波和声音。真空管放大微弱的音频信号，并将这些信号叠加在无线电波上。1918 年，Edwin Armstrong 发明了 超外差接收机，它可以在众多信号或信源中选择，还可接收远距离信号。于是无线广播在1920 年得到空前发展。1920 年至1935 年只有调幅被使用，而Armstrong 于1935 年发明了调频。 一战通过电阻和电容等元件推动了无线传播的发展。1920 年，匹兹堡的KDKA 广播首先预定了Westinghouse Corp 的无线广播。1925 年，贝尔实验室发明了一台用电来记录声音的设备。 但是，二战对于元件的发展却有惊人的效果，因为战争将要面临全世界各地的气候。 也许二战之前最重要的发明之一是雷达。雷达是由一组英国科学家研究无线电波反射的产物。雷达是Radio Detection And Ranging 的首字母缩略词。通过无线电微波的回音来测量一个物体的距离及方向。它用于航空、船侦查、核武器控制、导航及其他形式的监控。由于战争，电路学，视频，脉冲技术及微波传送被改进并快速地被电视产业接受。1950 年中期，电视已经超越广播被用于家庭使用及娱乐。 二战后，电子管用来开发第一台电脑，但是由于它们的元件大小变得不实际。1946 年印制电路开始应用于微型管。1947 年，贝尔实验室的一组工程师发明了晶体管。因此，John Bardeen,Walter Brattain,Willian Shockley 获得了诺贝尔奖，但是很少人可以预知到晶体管可 以多么快速，激烈地改变着世界。晶体管的功能与真空管相似，但尺寸小，重量轻，功耗低，工作更为可靠。它由金属电极和半导体材料构成，成本较低。 Geoffrey W.A.Dummer 于1952 年提出集成电路的概念，他是工作在皇室雷达机构的电子专家。在整个20 世纪50 年代，晶体管是大量生产的单一晶片及分立元件。总的半导体电路迈出了简单的一小步，它把晶体管和二极管（有源器件）和电容、电阻（电阻器件）组成 在一个简单的晶片上。半导体工业和非集成电路同时在德州仪器及费尔柴尔德半导体公司形成。到1961 年，一定数量的企业全面生产集成电路，并且为了从多方面适应这种技术，快速改变设备设

电子信息专业英语

Unit 1 The Development of Electronics Electronics is a part of the larger field of electricity. The basic principles of electricity are also common to electronics, Modern advances in the fields of computers, control systems, communications have a close relationship with electronics. Electronics is a scientific study of electronic components such as electron tubes, diodes, transistors, integrated circuits and so on, electronic circuits and its applications. Electronics began in 1883, when Thomas Edison discovered the vacuum diode as part of his research on materials for a practical electric light. Edison’s discovery laid the foundation of electronics. The development of electronics has had three important steps: the first step was electron tube invented by Fleming, an English physicist in 1904. This invention led the world to step into an electronic era. During that time the application of electron tubes was in the communication industry, first in radios and later in televisions. Because of their large size and wasted power, most of their applications are replaced by transistors today. The invention of transistor was the second step in electronics. A transistor was made from semiconductor material. The early transistors were made from germanium. The most visible application of transistors was in small, portable AM broadcast receivers. Silicon transistor began to replace germanium transistors in the late 1950s, which made possible the next revolutionary step in electronics. And the third step was the development of integrated circuits (ICs), which made a commercial success in electronics. Jack Kilby, an American scientist, made the first single chip IC in 1985, which laid foundation of microminiaturization and integration. The development of IC created microelectronics and brought a wide use of electronics in everyday items. It created the modern computer industry and restructured communications. Without it, man could not explore space or fly to the moon. Electronic technology is developing rapidly in the world. And electronics industry is equipped to make yet another giant step forward.

电子信息类专业英语第五单元译文 李白萍主编

电子信息类专业英语（第二版）李白萍主编第五单元译文 第五单元 A compact disc (CD) is a laser-read (also termed “optically read”) data storage device on which audio, video, or textual material can be stored. Although it has been used primarily to record stereophonic sound and has supplanted the long-playing PHONOGRAPH record as the principal medium for music storage, it offers a huge potential as the medium for the storage of massive amounts of many types of information.[1] 一个光盘（CD）是在其上的音频，视频或文本材料可被存储在激光读取（也称为“光学读取”）数据存储设备。虽然它被主要用来记录立体声声音，并已经取代了留声机成为了主要的音乐存储媒体，但它作为能存储大量多种信息的媒体仍具有巨大的潜力。 Unlike the conventional phonograph record, the CD stores information in digital form. Stereophonic (two-channel) sound signals are digitally sampled at a rate of 44,100 times per second per channel. Each sample is expressed as a binary number value consisting of 16 binary digits, or bits. The sampled digital values, along with error correction data, tracking codes, and cueing data, are recorded on a digital tape, which is used to make compression-molded plastic discs 12 cm (4.72in) in diameter, each covered by a thin, reflective metallic layer and protected by a clear plastic coating.[2] During playback, a low-powered laser beam reads the digital data through the reflective rear surface of the disk.[1] 与传统的照片记录不同，光盘以数字形式存储的信息。立体声（双声道）声音信号以每秒44,100次每信道的速率进行数字采样。每个样本被表示为二进制数的值由16个二进制数位，或比特组成。样本数值，以及误差校正数据，跟踪代码和暗示的数据，记录在数字磁带上，它是用来制成直径为12厘米（4.72英寸）的压缩成形的塑料盘，各由一个薄的、反射性的金属层和一个透明的塑料涂层保护。在播放过程中，低功率激光束通过光盘表面的反射后读取数据。 The CD improves over conventional records and tape recordings with its more uniform and accurate frequency response, a complete absence of background noise, a wider dynamic range (the difference between the softest and loudest recordable musical sounds), and longer wear—since nothing mechanical touches the surface of the disc when it is played. 光盘改善了传统的记录和录音------更均匀、精确的频率响应，完全没有背景噪音，更宽的动态范围（不同于最柔软的和最大可录制音乐地声音），而且更耐用。因为当它被播放时没有机械接触光盘的表面。 Introduced in 1992, the Sony MiniDisc measures only 6.35cm(2.5in) in diameter, but it can be used to record as well as play up to 74 minutes of music. Its small size is
