Resistor

A resistor is a two-term inal electro nic comp onent that opposes an electric curre nt by produc ing a voltage drop betwee n its termi nals in proport ion to the curre nt, that is ,in accorda nee with Ohm ' s law :V=IR .The electrical resistance R is equal to the voltage drop V across the resistor divided by the current I through the resistor. 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 . A cha nging curre nt in the first circuit creates a cha nging

magn etic field; in turn, this magn etic field in duces a cha nging voltage in the sec ond circuit. By add

ing a load to the sec on dary circuit, one can make curre nt flow in the tran sformer, thus tran sferri ng

en ergy from one circuit to the other.

变压器是一种通过感应耦合将电能从一个电路传输到另一个电路的装置。在第一电路中的一

个变化的电流创建一个不断变化的磁场;反过来,这个磁场诱导第二个电路中的电压变化。

通过向二次回路中增加负载,使电流在变压器中流动,从而将能量从一个电路传递到另一个

电路中。

Relay

A relay is an electrical switch that ope ns and closes un der the con trol of ano ther electrical circuit .

In the origi nal form ,the switch is operated by an electromag net to ope n or close one or many sets of con tacts. It was inven ted by Joseph Henry in 1835. Because a relay is able to con trol an output circuit of higher power tha n the in put circuit ,it can be con sidered to be, in a broad sen se, a form of an electrical amplifier. 继电器是一种电子开关,控制另一个电路的打开和关闭。在原始形式中,该开关是由一个电磁铁操作,打开或关闭一个或多个触点。它是由约瑟夫亨利在1835年发明的。由于继电器

能够控制比输入电路功率更高的输出电路,广义上说,它可以被认为是电子放大器的一种形

式。

Types of circuits

In any circuit where the on ly oppositi on to the flow of electr ons is resista nee , there is a defi nite relati on

ship betwee n the values of voltage , curre nt, and resista nee. This relati on ship was discovered by George Sim on Ohm in 1827. It is known as Ohm ' s law.

任何电路中电阻仅仅阻止电子的流动,电压,电流和电阻的值之间有一个明确关系。这种关

系在1827年由格奥尔格西蒙欧姆发现。它被称为欧姆定律。

Duality

Because of the strong similarity between the Fourier analysis and synthesis equations in continuous time , there is a duality between the time domain and frequency domain . However , for the discrete-time Fourier transforms of aperiodic signals , no similar duality exists , since aperiodic signals and their Fourier transforms are very different kinds of functions : Aperiodic discrete-time signals are , of course, aperiodic sequences , while their Fourier transforms are always periodic fun cti ons of a con ti nu ous freque ncy variable .

由于傅里叶分析和合成方程在在连续时间上有很大的相似性,有一个时域和频域之间的二元

性。然而,对于非周期信号的离散傅里叶变换,没有类似的二元性存在,由于非周期信号和它

们的傅立叶变换有着迥然不同的功能:当然,非周期离散时间信号,非周期序列,然而他们的傅

里叶变换总是周期性的频率连续变化的函数。

Network Con figurati on

Broadly speaking , there are two types of network configuration based on their

layout ,peer-to-peer n etworks and clie nt/server n etwork.

Peer-to-peer networks are more commonly implemented where less than ten computers are in volved and where strict security is n ot n ecessary. All computers have the same status , hence the term ” peer ” a nd they com muni cate with each other on an equal foot ing .Files , such as word processing or spreadsheet documents ,can be shared across the network and all the computers on the n etwork can share

devices ,such as prin ters or sca nners ,which are conn ected to any one computer.

广义地说,有基于两种类型网络配置的的布局,对等网络和客户机/服务器网络。

对等网络较为普遍实现,其中不到10台计算机参与并且不需要很严格的安全性。所有计算

机都具有相同的地位,因此被称为“对等”,而且他们平起平坐相互通信。文件,例如文字

处理或电子表格文档,可以通过网络共享来和所有的网络上的计算机进行设备共享,打印机

或者扫描仪,可以连接到任何一台计算机。

电气工程及其自动化专业英语第二章课文翻译

第二章第一篇 To say that we live in an age of electronics is an understatement. From the omnipresent integrated circuit to the equally omnipresent digital computer, we encounter electronic devices and systems on a daily basis. In every aspect of our increasingly technological society— whether it is science, engineering, medicine, music, maintenance, or even espionage—the role of electronics is large, and it is growing. 谈论关于我们生活在一个电子学时代的论调是一种空泛的论调。从无处不在的集成电路到同样无处不在的数字计算机,我们在日常活动中总会遇到电子设备和电子系统。在我们日益发展的科技社会的方方面面——无论是在科学、工程、医药、音乐、维修方面甚至是在谍报方面——电子学的作用是巨大的,而且还将不断增强。 In general, all of the tasks with which we shall be concerned can be classified as "signal-processing“tasks. Let us explore the meaning of this term 一般说来,我们将要涉及到的工作被归结为“信号——处理”工作,让我们来探究这个术语的含义吧。 A signal is any physical variable whose magnitude or variation with time contains information. This information might involve speech and music, as in radio broadcasting, a physical quantity such as the temperature of the air in a room, or numerical data, such as the record of stock market transactions. The physical variables that can carry information in an electrical system are voltage and current. When we speak of "signals", therefore, we refer implicitly to voltages or currents. However, most of the concepts we discuss can be applied directly to systems with different information-carrying variables. Thus, the behavior of a mechanical system (in which force and velocity are the variables) or a hydraulic system (in which pressure and flow rate are the variables) can often be modeled or represented by an equivalent electrical system. An understanding of the behavior of electrical systems, therefore, provides a basis for understanding a much broader range of phenomena. 信号就是其与时间有关的量值或变化包含信息的任何物理变量。这种信息或许像无线电广播的演讲和音乐,或许是像室内温度的物理量,或许像股市交易记录的数字数据。在电气系统中能够载有信息的物理变量是电压和电流。因此当我们谈到“信号”,我们不言而喻指的是电压和电流,然而,我们要讨论的大多数概念是可以被直接应用于载有不同信息的变量的系统,因此,一个机械系统(在这个系统中力和速度是其变量)或者液压系统(在这个系统中压力和流速是其变量)的性能通常可以用一个等效的电气系统来模拟或表示。因此,我们对于电气系统性能的理解为理解更宽领域的现象打下了一个基础。 A signal can carry information in two different forms. In an analog signal the continuous variation of the voltage or current with time carries the information. An example, in Fig.2-l, is the voltage produced by a thermocouple pair when the two junctions are at different temperatures. As the temperature difference between the two junctions varies, the magnitude of the voltage across the thermocouple pair also varies. The voltage thus provides an analog representation of the temperature difference. 一个信号可以以两种形式来承载信息。在一个模拟信号中电压或电流随时间而产生的连续变化载有信息。在图2-1中,当一对热电偶的接头处于不同的温度时由热电偶所产生的电压就是一个例子。当两个接头之间的温度差改变时,一对热电偶两端的电压也将改变。于是电压就提供了温度差的模拟表现形式 The other kind of signal is a digital signal. A digital signal is one that can take on values within two discrete ranges. Such signals are used to represent ON-OFF or YES-NO information. An ordinary household thermostat delivers a digital signal tocontrol the furnace. When the

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

Most people can formulate a mental picture of a computer, but computers do so many things and come in such a variety of shapes and sizes that it might seem difficult to distill their common characteristics into an all-purpose definition. At its core, a computer is a device that accepts input, processes data, stores data, and produces output, all according to a series of stored instructions. Computer input is whatever is put into a computer system. Input can be supplied by a person, by the environment, or by another computer. Examples of the kinds of input that a computer can accept include the words and symbols in a document, numbers for a calculation, pictures, temperatures from a thermostat, audio signals from a microphone, and instructions from a computer program. An input device, such as a keyboard or mouse, gathers input and transforms it into a series of electronic signals for the computer. In the context of computing, data refers to the symbols that represent facts, objects, and ideas. Computers manipulate data in many ways, and we call this manipulation processing. The series of instructions that tell a computer how to carry out processing tasks is referred to as a computer program, or simply a "program." These programs form the software that sets up a computer to do a specific task. In a computer, most processing takes place in a component called the central processing unit (CPU), which is sometimes described as the"brain" of the computer. A computer stores data so that it will be available for processing. Most computers have more than one location for storing data, depending on how the data is being used. Memory is an area of a computer that temporarily holds data that is waiting to be processed, stored, or output. Storage is the area where data can be left on a permanent basis when it is not immediately needed for processing. Output is the results produced by a computer. Some examples of computer output include reports, documents, music, graphs, and pictures. An output device displays, prints, or transmits the results of processing. Computers are versatile machines, which are able to perform a truly amazing assortment of tasks, but some types of computer are better suited to certain tasks than other types of computers. Computers can be categorized as personal computer, handheld computers, workstations, mainframes, supercomputers , and servers. 大多数人可以制订一个电脑精神的图片,但电脑做很多事情,出现这样的形状和大小不同,它似乎难以提炼成一个全能的定义,它们的共同特点。在其核心,一台计算机是一种装置,它接受输入,处理数据,存储数据,并产生输出,根据对所有存储一系列指示。 什么是计算机输入到计算机系统的压力。输入可提供的一人,由环境,或由另一台计算机。对输入的各种例子,一个计算机可以接受包括文字和符号的文件,规定计算,图片,从恒温器的温度数字,音频信号从一个麦克风,从电脑程序指令。一个输入设备,如键盘或鼠标,集输和转换成一个电子信号的计算机的一系列。 在计算中,数据是指以符号代表的事实,对象和想法。计算机操作在很多方面的数据,我们称之为操作处理。一系列的指令,告诉计算机如何进行处理任务,被称为一个计算机程序,或只是一个“程序”。这些方案形成了软件,建立了计算机做特定的任务。在计算机中,大部分处理发生在一个组件的地方称为中央处理单元(CPU),有时为“大脑的计算机”来形容。 计算机存储数据,以便它会被用作处理可用。大多数计算机有多个用于存储数据的位置,这取决于数据如何被使用。内存是计算机的一个领域,数据是暂时持有等待处理,存储或输出。在数据存储,是可以在一个地区长期离开时,没有立即处理所需。 输出是由电脑产生的结果。电脑输出的一些例子包括报告,文件,音乐,图形,图片。输出设备显示,打印,或传送的处理结果。 电脑是多功能机,它能够执行各种各样的任务十分惊人,但某些类型的计算机更适合比其他类型的计算机的某些任务。计算机可以被归类为个人电脑,掌上电脑,工作站,大型机,超级计算机和服务器。

As time progressed after the inven ti on of LSI in tegrated circuits, the tech no logy improved and chips became smaller, faster and cheaper. The functions performed by a processor were impleme nted using several differe nt logic chips. In tel was the first compa ny to in corporate all of these logic comp onents into a si ngle chip, this was the first microprocessor. A microprocessor is a complete computati on engine that is fabricated on a sin gle chip. A microprocessor executes a collecti on of machi ne in struct ions that tell the processor what to do. Based on the in struct ions, a microprocessor does three basic things: https://www.sodocs.net/doc/0e6648539.html,ing the ALU (Arithmetic/Logic Unit), a microprocessor can perform mathematical operatio ns like additi on, subtract ion, multiplicatio n and divisi on; 2.A microprocessor can move data from one memory location to another; 3.A microprocessor can make decisi ons and jump to a new set of in struct ions based on those decisi ons. There may be very sophisticated things that a microprocessor does, but those are its three basic activities. Microprocessor has an address bus that sends an address to memory, a data bus that can send data to memory or receive data from memory, an RD(read) and WR(write) line that lets a clock pulse sequenee the processor and a reset li ne that resets the program coun ter to zero(or whatever) and restarts executi on. And let ' s assume that both the address and data buses are 8 bits wide here. Here are the comp onents of this simple microprocessor: 1. Registers A, B and C are simply latches made out of flip-flops. 2. The address latch is just like registers A, B and C. 3. The program coun ter is a latch with the extra ability to in creme nt by 1 whe n told to do so, and also to reset to zero whe n told to do so. 4. The ALU could be as simple as an 8-bit adder, or it might be able to add, subtract, multiply and divide 8- bit values. Let ' s assume the latter here. 5. The test register is a special latch that can hold values from comparisons performed in the ALU. An ALU can normally compare two numbers send determine if they are equal, if one is greater

2、应力和应变 在任何工程结构中独立的部件或构件将承受来自于部件的使用状况或工作的外部环境的外力作用。如果组件就处于平衡状态,由此而来的各种外力将会为零,但尽管如此,它们共同作用部件的载荷易于使部件变形同时在材料里面产生相应的内力。 有很多不同负载可以应用于构件的方式。负荷根据相应时间的不同可分为: (a)静态负荷是一种在相对较短的时间内逐步达到平衡的应用载荷。 (b)持续负载是一种在很长一段时间为一个常数的载荷, 例如结构的重量。这种类型的载荷以相同的方式作为一个静态负荷; 然而,对一些材料与温度和压力的条件下,短时间的载荷和长时间的载荷抵抗失效的能力可能是不同的。 (c)冲击载荷是一种快速载荷(一种能量载荷)。振动通常导致一个冲击载荷, 一般平衡是不能建立的直到通过自然的阻尼力的作用使振动停止的时候。 (d)重复载荷是一种被应用和去除千万次的载荷。 (e)疲劳载荷或交变载荷是一种大小和设计随时间不断变化的载荷。 上面已经提到,作用于物体的外力与在材料里面产生的相应内力平衡。因此,如果一个杆受到一个均匀的拉伸和压缩,也就是说, 一个力,均匀分布于一截面,那么产生的内力也均匀分布并且可以说杆是受到一个均匀的正常应力,应力被定义为 应力==负载 P /压力 A, 因此根据载荷的性质应力是可以压缩或拉伸的,并被度量为牛顿每平方米或它的倍数。 如果一个杆受到轴向载荷,即是应力,那么杆的长度会改变。如果杆的初始长度L和改变量△L已知,产生的应力定义如下: 应力==改变长△L /初始长 L 因此应力是一个测量材料变形和无量纲的物理量 ,即它没有单位;它只是两个相同单位的物理量的比值。 一般来说,在实践中,在荷载作用下材料的延伸是非常小的, 测量的应力以*10-6的形式是方便的, 即微应变, 使用的符号也相应成为ue。 从某种意义上说,拉伸应力与应变被认为是正的。压缩应力与应变被认为是负的。因此负应力使长度减小。 当负载移除时,如果材料回复到初始的,无负载时的尺寸时,我们就说它是具有弹性的。一特定形式的适用于大范围的工程材料至少工程材料受载荷的大部分的弹性, 产生正比于负载的变形。由于载荷正比于载荷所产生的压力并且变形正比于应变, 这也说明,当材料是弹性的时候, 应力与应变成正比。因此胡克定律陈述, 应力正比于应变。 这定律服从于大部分铁合金在特定的范围内, 甚至以其合理的准确性可以假定适用于其他工程材料比如混凝土,木材,非铁合金。 当一个材料是弹性的时候,当载荷消除之后,任何负载所产生的变形可以完全恢复,没有永久的变形。
