1.(P1) Computer science deals with the theoretical foundations of information and computation, together with

practical techniques for the implementation and application of these foundations, such as programming language theory, computational complexity theory, computer graphics and human-computer interaction.

计算机科学涉及信息和计算的理论基础，以及这些基础的实施和应用的实际技术，如编程语言理论，计算复杂性理论，计算机图形学和人机交互。

2.(P17) The most important piece of graphics hardware is the graphics card, which is the piece of equipment

that renders out all images and sends them to a display. There are two types of graphics cards: integrated and dedicated. An integrated graphics card, usually by Intel for use in their computers, is bound to the motherboard and shares RAM (Random Access Memory) with the CPU, reducing the total amount of RAM available. This is undesirable for running programs and applications that use a large amount of video memory. A dedicated graphics card has its own RAM and Processor for generating its images, and does not slow down the computer. Dedicated graphics cards also have higher performance than integrated graphics cards. It is possible to have both dedicated and integrated graphics card, however once a dedicated graphics card is installed, the integrated card will no longer function until the dedicated card is removed.

最重要的一块图形硬件是显卡，是一件呈现出所有的图像，并将它们发送到一个显示器的设备。有两种类型的显卡：集成和专用。集成的显卡，通常由英特尔在他们的计算机上使用，被绑定到主板并且与中央处理器共享内存（随机存取存储器），减少了可用的内存总量。这对于使用大量视频内存的程序和应用来说是不可取的。

专用显卡有它自己的内存和处理器，用于生成它的图像，并且不会减慢计算机的速度。专用显卡也比集成显卡有更高的性能。有可能既有专门的也有集成的显卡，但是，一旦安装了专用显卡，集成显卡将不再起作用，直到专用显卡被移除。

3.(P18) Channel I/O requires the use of instructions that are specifically designed to perform（执行）I/O

operations. The I/O instructions address（处理）the channel or the channel and device; the channel asynchronously（异步的）accesses all other required addressing and control information. This is similar to DMA, but more flexible.

I/O通道需要使用专门设计来执行I/O操作的指令。I/O指令处理通道或通道和设备；通道异步访问所有其他所需的寻址和控制信息。这是类似于DMA，但更灵活。

4.(P19) 调制解调器是在模拟和数字信号之间进行转换的设备，它经常用于实现计算机之间通过电话线的互相通

信。如果两个调制解调器可同时互相发送数据，那么它们采用的就是全双工工作方式；如果一次只有一个调制解调器可以发送数据，那么它们采用的则是半双工工作方式。

Modem is a device that converts analog（模拟）signals to digital signals or conversely（相反地）. It is often used to communicate between computers via（渠道）telephone lines. If the two modems can send data to each other, they use full-duplex mode; if only one modem can transmit data, they use half-duplex mode.

6.(P21) We many have defined our last generation of computer and begun the era of generationless

computers. Even though computer manufactu rers talk of “fifth” and “sixth” generation computers, this talk is more a marketing play than a reflection of reality.

我们已经定义了我们的上一代计算机，并且开始了计算机的无代时代。即使计算机制造商谈论的“第五”和“第六”

代电脑，这个说法比起现实的反映更像是一个营销游戏。

7.(P21) Although microprocessors are still technically considered to be hardware, portions of their function are

also associated with computer software. Since microprocessors have both hardware and software aspects they are therefore often referred to as firmware.

虽然微处理器仍然在技术上被认为是硬件，它们的部分功能也与计算机软件有联系。因为微处理器有硬件和软件两个方面，因此，他们往往被称为固件。

8.(P22) Electronic hardware consists of interconnected（互联的）electronic components（元件/组件）which

perform analog or logic operations on received and locally stored information to produce as output or store resulting new information or to provide control for output actuator mechanisms（机制）.

Electronic hardware can range from individual chips/circuits to distributed information processing systems.

Well-designed electronic hardware is composed of functional modules which inter-communicate via precisely defined interfaces.

电子硬件是由互连的电子元件组成的，这些电子元件对接收到的和本地存储的信息执行模拟或逻辑运算，以产生输出或存储产生的新信息或提供控制输出执行机构的机制。

电子硬件的范围可以从单独的芯片/电路到分布式信息处理系统。精心设计的电子硬件是由相互通信的功能模块，通过精确定义的接口组成。

9.

10.(P23) Hardware logic is primarily a differentiation of the data processing circuitry from other more generalized

circuitry. For example, nearly all computers include a power supply which consists of circuitry not involved in data processing but rather powering the data processing circuits. Similarly, a computer may output information to a computer monitor or audio amplifier which is also not involved in the computational process.

硬件逻辑主要是从其他更广义电路的数据处理电路的分化。例如，几乎所有的计算机都包括一个电源，该电源由不涉及数据处理的电路组成，而是提供数据处理电路的电源。同样地，计算机可以输出信息到计算机监视器或音频放大器，也不涉及计算过程。

11.(P23 3段)

12.(P30) The Space Shuttle avionics software represents a successful integration of many of the computer

industry's most advanced software engineering practices and approaches. Beginning in the late 1970's this software development and maintenance project has evolved one of the world's most mature software processes applying the principles of the highest levels of the Carnegie Mellon University Software Engineering, Institute's Capability Maturity Model, Trusted Software methodology, and ISO 9001 Standards.

This software process, considered to be a “best practice” by many software industry organizations includes state-of-the-practice software reliability engineering methodologies. Lve-critical Shuttle avionics software produced by this process is recognized to be highest quality and highest reliability software in operation in the world.

航天飞机的航空电子设备软件代表了许多计算机行业最先进的软件工程实践和方法的成功整合。从十九世纪七十年代后期开始，这个软件开发和维护项目已经发展为世界上最成熟的软件过程之一。应用最高水平的卡内基梅隆大学软件工程研究所的能力成熟度模型，可信软件方法，和国际标准化组织9001标准的原则。这个软件过程，被许多软件行业组织认为是一个“最佳实践”，包括实践性的软件可靠性工程方法论。由这个过程产生的

关键的航天飞机航空电子设备软件，被认为是世界上公认的质量最高的和可靠性最高的软件。

13.(P35) Unix was originally written in assembly language. Ken Thompson wrote B, mainly based on BCPL,

based on his experience in the MULTICS project. B was replaced by C, and Unix, rewritten in C, developed into a large, complex family of inter-related operating systems which have been influential in every modern operating system. The Unix-like family is a diverse group of operating systems, with several major sub-categories including System V, BSD, and Linux.

UNIX是用汇编语言写的。肯汤普森写的B，主要基于BCPL，基于他在Multics项目的经验。B是由C和UNIX 所取代，用C重写，发展成一个庞大的、复杂的相互关联的操作系统，对所有现代操作系统有影响。类UNIX 系统是一组不同的操作系统中，几个主要的子类包括系统V，BSD，Linux。

14.(P37) Log management module plays an important role in the massive spatial database management

system. There are few three-dimensional spatial database management systems with pertinent log management sub-system, or the administrator can only use the log, which is attached by database system, to recover the data. To improve this issue, hierarchical structure of the log management module should be taken into account. The overall design of three-dimensional spatial database management system is as follows: three-dimensional spatial database (including database system, file system), three-dimensional spatial data engine, and three-dimensional space management tools.

日志管理模块在海量空间数据库管理系统中起着重要的作用。三维空间数据库管理系统与相关的日志管理子系统很少，或管理员只能使用数据库系统所附的日志恢复数据。为了改善这个问题，应考虑日志管理模块的层次

结构。三维空间数据库管理系统的总体设计是：三维空间数据库（包括数据库系统、文件系统）、三维空间数据引擎和三维空间管理工具。

15.(P37) According to the 3D spatial database management system design, we divided the log management

into three layers. The log management system includes monitor layer of three-dimensional spatial database's triggers and file database system operations recording statements, interface layer of log management module of three-dimensional spatial database engine, and graphical user interface layer of log management module of three-dimensional spatial data management tools.

根据三维空间数据库管理系统的设计，将日志管理分为三个层次。日志管理系统包括监控层、接口层和图形用户界面层。监控层包括三维空间数据库的触发器和文件数据库系统操作记录报表。接口层包括日志管理模块的三维空间数据库引擎。图形用户接口界面层包括日志管理模块的三维空间数据管理工具。

16.(P37 3段)

18.(P72) E-mail is a pipeline to thousands of experts on virtually everything; it is a means of meeting people with

similar interests or problems. What it's not is live chat—real-time conversations like those on ham radio or CB.

对于成千上万的专家来说，电子邮件是一条通向任何事的管道，它是和有类似兴趣和问题的人交友的一种方式。

它不是实时聊天-使用业余无线电或CB进行实时交谈。

19.(P125) Information Security Attributes: or qualities, i.e., Confidentiality, Integrity and Availability (CIA).

Information System are composed of three main portions, hardware, software and communications with the purpose to help identify and apply information security industry standards, as mechanisms of protection and prevention, at three levels or layers: physical, personal and organizational. Essentially, procedures or policies are implemented to tell people (administrators, users and operators) how to use products to ensure information security within the organizations.

信息安全属性或特质，即保密性，完整性和可用性（CIA）。信息系统是由三个主要部分组成，在物理，个人和组织三个层次或层作为保护和预防机制。三个部分为硬件，软件和通信，目的是帮助识别和应用信息安全行业标准。从本质上讲，程序或政策的实施，告诉人们（管理员，用户和运营商）如何使用产品，以确保组织内的信息安全。

英文翻译练习（一） The status of Philosophy in Chinese culture has always been regarded as a comparison with that of religion in other cultures. In China, Philosophy is the concerned field by each educated one. Long time ago in China, a person would firstly accept enlightened education in Philosophy if he could be given education. Children should read the Analects, Mencius, The great Learning, The Doctrine of mean once they entered school. The Four Books were regarded as the most important documents after Song(regarded as “new Confucianism”in west).When children began to learn words, the commonly used textbook is Three Words, in which every three words a group, every six words one sentence, and the even sentence rhyme has rhyme, easy to read aloud and easy to remember. In fact, this book is used to learn words for Chinese children. The first sentence of Three Words “Man’s nature is good at birth.” Is the basic idea of philosophy of Mencius.

Americans are much more likely than citizens of other nations to believe that they live in a meritocracy, i.e. Government by people selected according to merit. But this self-image is a fantasy: America actually stands out as an advanced country in which it matters most who your parents were, the country in which those born on one of society’s lower rungs have the least chance of climbing to the top or even to the middle. And if you ask why America is more class-bound in practice than the rest of the Western world, a large part of the reason is that our government falls down on the job of creating equal opportunity. The failure starts early: in America, the holes in the social safety net mean that both low-income mothers and their children are all too likely to suffer from poor nutrition and receive inadequate health care. It continues once children reach school age, where they encounter a system in which the affluent send their kids to good, well-financed public schools or, if they choose, to private schools, while less-advantaged children get a far worse education. 美国人可能比任何其他国家的人都更相信他们生活在一个精英制度之下，人们推选的政府也是据其优势。然而，这个自我形象是一种幻想：作为先进国家，实际上美国的突出特点是出身至关重要，在这个国度里，来自社会底层的人几乎没有机会爬到社会中层，更不用说社会顶层。 如果你要问为什么实际上美国比其他西方国家都要阶级分明，主要原因就是我们的政府在创造公平机会方面的失败。 这种不公平很早以前就开始了：在美国，由于社会安全网存在漏洞，这就意味着低收入的母亲和他们的孩子完全有可能存在营养不良，得不到足够的医疗服务。孩子到了上学年龄这种情况也不会得到改观，他们所遇到的体制是富人可以送自己的孩子到资金充足的好的公立学校上学，如果愿意，还可以从送到私立学校上学，而穷人孩子接受的教育却非常差。

1.2 总线互连 总线是连接两个或多个设备的通信通路。总线的关键特征是，它是一条共享传输介质。多个设备连接到总线上，任一个设备发出的信号可以为其他所有连接到总线上的设备所接收。如果两个设备同时传送，它们的信号将会重叠，引起混淆。因此，一次只能有一个设备成功地（利用总线）发送数据。 典型的情况是，总线由多条通信通路或线路组成，每条线(路)能够传送代表二进制1和0的信号。一段时间里，一条线能传送一串二进制数字。总线的几条线放在一起能同时并行传送二进制数字。例如, 一个8位的数据能在8条总线线上传送。 计算机系统包含有多种不同的总线，它们在计算机系统层次结构的各个层次提供部件之间的通路。连接主要计算机部件(处理机, 存储器, I/O)的总线称为系统总线。系统总线通常由50~100条分立的(导)线组成。每条线被赋予一个特定的含义或功能。虽然有许多不同的总线设计，但任何总线上的线都可以分成三个功能组：数据线、地址线和控制线。此外可能还有为连接的模块提供电源的电源线。 数据线提供系统模块间传送数据的路径，这些线组合在一起称为数据总线。典型的数据总线包含8、16或32根线，线的数量称为数据总线的宽度。因为每条线每次传送1位，所以线的数目决定了每次能同时传送多少位。数据总线的宽度是决定系统总体性能的关键因素。 地址线用于指定数据总线上数据的来源和去向。例如，如果处理机希望从存储器中读一个字的数据，它将所需要字的地址放在地址线上。显然，地址总线的宽度决定了系统最大可能的存储器容量。 控制线用来控制对数据线和地址线的访问和使用。由于数据线和地址线被所有部件共享，因此必须用一种方法来控制它们的使用。控制信号在系统模块之间传送命令和定时信息。定时信息指定了数据和地址信息的有效性，命令信号指定了要执行的操作。 大多数计算机系统使用多总线，这些总线通常设计成层次结构。图1.3显示了一个典型的高性能体系结构。一条局部总线把处理机连接到高速缓存控制器，而高速缓存控制器又连接到支持主存储器的系统总线上。高速缓存控制器集成到连接高速总线的桥中。这一总线支持连接到：高速LAN、视频和图形工作站控制器，以及包括SCSI 和FireWire的局部外设总线的接口控制器。低速设备仍然由分开的扩充总线支持，用一个接口来缓冲该扩充总线和高速总线之间的通信流量。 PCI 外部设备互连是流行的高带宽的、独立于处理机的总线，它能够作为中间层或外围设备总线。当前的标准允许在66MHz频率下使用多达64根数据线，其原始传输速率为528MB/s, 或4.224Gbps。PCI被设计成支持各种各样基于微处理机的配置，包括单处理机和多处理机的系统。因此，它提供了一组通用的功能。PCI使用同步时序以及集中式仲裁方案。 在多处理机系统中，一个或多个PCI配置可通过桥接器连接到处理机的系统总线上。系统总线只支持处理机/高速缓存单元、主存储器以及PCI桥接器。使用桥接器使得PCI独立于处理机速度，又提供快速接收和传送数据的能力。 2.1 光存储介质：高密度存储器 2.1.1 光盘 光盘技术最终可能使磁盘和磁带存储淘汰。用这种技术，磁存储器所用的读/写头被两束激光代替。一束激光通过在光盘上刻制微小的凹点，对记录表面进行写；而另一束激光用来从光敏感的记录表面读取数据。由于光束容易被偏转到光盘上所需要的位置，所以不需要存取臂。 对用户而言，光盘正成为最有吸引力的选择。它们(光盘)对环境变化不太敏感，并且它们以每兆字节比磁盘低得多的存储器价格提供更多的直接存取存储器。光盘技术仍在出现，并且还需要稳定；然而，目前有三种主要类型的光盘。它们是CD-ROM、WORM盘和磁光盘。 CD-ROM 1980年引入的，非常成功的CD，或紧密盘是设计来提高音乐的录音重放质量的光盘。为了制作一张CD，把音乐的模拟声音转换成等价的数字声音，并且存储在一张4.72英寸的光盘上。在每张光盘上可以用数字格式（用20亿数字位）记录74分钟的音乐。因为它的巨大存储容量，计算机工业的企业家们立刻认

计算机专业英语翻译 1.1细看处理器与主存储器 我们已经了解到所有计算机有类似的能力且能执行相同的功能,尽管一些可能比其他的快。我们知道电脑系统有输入、输出、仓储、加工的元件,还知道处理器是计算机系统的“智能”部分,并且知道一个简单的计算机系统可以有几个处理器。我们已经讨论了在电脑系统中数据以被称作位的电子状态来表示。我们现在准备阐释计算机系统核心的内部活动——处理器。 电脑的内部操作很有趣,但真的没有什么奥秘的事。这种神秘性存在于那些道听途说和相信科幻作家的人心中。计算机是不会思考的电子设备,它必须插入电源,就像一台烤面包机或一盏灯。 毫不夸张地讲,市场上有几百种不同类型的计算机在销售。每种类型可能都很复杂,但每个处理器,有时被称为中央处理器或者说CPU,只有两个基本部分:控制单元,算术和逻辑单元。主存储器在处理器的内部发挥着重要作用。这三个——主存、控制单元,算术和逻辑单元——一起工作。让我们来看看他们之间的功能和联系。 与磁辅助存储设备,如磁带、磁盘相比,主存没有移动部件。没有机械的运动,数据可以以电子的速度被存取访问,接近光速。今天大多数电脑的主存使用 DRAM(动态随机访问存储器)技术。先进的DRAM芯片大约有1/8邮票那么大,大约可以储存256,000万位或多于25,600,000字符的数据。 主存储器,或者主存,提供给处理器的程序和数据暂时的存储。在可执行程序或数据 本材料版权归八舍109所有，任何人以任何形式使用请自觉支付版税～

可以被处理之前,所有的程序和数据必须被从输入设备(如VDT)或从辅助存储(如磁盘)转移到主存储器。主要的存储空间总是很少;因此,在一个程序被执行后,它占领的储藏空间会被重新分配给另一个等待执行的程序。 图1 - 1说明了所有的输入/输出(I / O)“读”或“用”主要的存储。图中(输入)探讨是在VDT上。消息被查询的形式,是通过一个渠道到主存储器(如同轴电缆)。消息被解释,处理机从辅助存储设备取出所需的程序和数据。程序和数据被“装好”,或移动,从辅助存储器到主存储器。这是一个无损阅读过程。也就是说,程序和数据被从主要存储器(暂时的)和辅助存储器(永久)中读取。数据根据程序指令被操作,报告被从主存储器写入到打印机。 一个程序指令或一块数据保存在的特定的主存单元被称为地址。地址允许程序指令和数据被存储,访问和加工。每一个地址的内容随着不同程序的执行和新的数据的处理是不断变化的。 主存储器的另一个名字是随机存取存储器,或RAM。一种特殊类型的主存储器,称为只读存储器(ROM),不能被程序员改写。ROM的内容被制造商作为“只读”所固化,设计在芯片的逻辑上,。当你打开微机系统,一个ROM中的程序自动启动计算机系统。然后ROM程序初步显示屏幕提示。 ROM的一种变种是可编程的只读存储器(PROM)。RPOM是让用户能装载“只读”的程序和数据的ROM。一旦一个程序被加载到PROM,它简直从不改变。然而,如果你本材料版权归八舍109所有，任何人以任何形式使用请自觉支付版税～ 需要能够修改内容的PROM,有EPROM,可擦写的PROM。在写操作之前,所有的储存单元必须被删除到同样的初始状态。 一个更具有吸引力的形式的主读存储器是电可擦可编程只读存储器(EEPROM)。在任何时候都可以写入,不需擦除原先内容,且只是更新寻址到的字节或多个字节。

AC500kV Substation Design In China Transmission and Substation Department,CPECC Abstract:Some brief informations about AC500kV substations in China,historical data of their design and essential design principles are presented in this paper.Some technical and engineering problems of AC500kV substation design and construction are discussed.It is emphasized to introduce the500kV substation scales,main electrical connections,selection of equipment and apparatus,insulation coordination,distribution switchyard,control and protection etc.Here we also discuss the policy of project cost control at present time and a prospective view of China AC substations in future. 1.Introduction The research and design of500kV substations in China were started in1977,and the first substation was put into operation in1981.From that time,because of the rapid development of electricity demand in China,design and construction of500kV substations have a great development.Especially in recent years,due to the increase of capital investment for power system construction from the State Government,500kV power system has developed even faster.Till1998about55substations(500kV)were already put into operation,in which217transformers were installed,and the total capacity reached60410 MVA.At present,there are30substations(total capacity26500MVA)under construction.In addition,it has been planned to construction/extends30substations(33transformers,24750 MVA)in accordance with the power delivery from Three Gorges Power Plant. A complete design system of AC500kV substation in China has been gradually established based on the past design and construction experiences and the use of new technologies.This system includes design procedures,design standards,rules and regulations, design management and so on. The essential design principles are safe and reliable,technically advanced,economical and reasonable,and good quality. 2.Size of Substations China is a developing country with broad territory.The economic development is very different from one region to another.In accordance with this fact,the500kV substation size is different at different time and for different region.

1.(P1) Computerscience deals with the theoreticalfoundations of informationand computation, together withpracticaltechniquesfortheimplementationand application of these foundations, such as programminglanguagetheory, computational complexitytheory, computergraphicsand human-computer interaction. 计算机科学涉及信息和计算的理论基础，以及这些基础的实施和应用的实际技术，如编程语言理论，计算复杂性理论，计算机图形学和人机交互。 2.(P17)The most important piece of graphics hardware is the graphics card, which is the piece of equipment that renders out all images and sends them to a display. There are two types of graphics cards: integrated and dedicated. An integrated graphics card, usually by Intel for use in their computers, is bound to the motherboard and shares RAM (Random Access Memory) with the CPU, reducing the total amount of RAM available. This is undesirable for running programs and applications that use a large amount of video memory. A dedicated graphics card has its own RAM and Processor for generating its images, and does not slow down the computer. Dedicated graphics cards also have higher performance than integrated graphics cards. It is possible to have both dedicated and integrated graphics card, however once a dedicated graphics card is installed, the integrated card will no longer function until the dedicated card is removed. 最重要的一块图形硬件是显卡，是一件呈现出所有的图像，并将它们发送到一个显示器的设备。有两种类型的显卡：集成和专用。集成的显卡，通常由英特尔在他们的计算机上使用，被绑定到主板并且与中央处理器共享内存（随机存取存储器），减少了可用的内存总量。这对于使用大量视频内存的程序和应用来说是不可取的。 专用显卡有它自己的内存和处理器，用于生成它的图像，并且不会减慢计算机的速度。专用显卡也比集成显卡有更高的性能。有可能既有专门的也有集成的显卡，但是，一旦安装了专用显卡，集成显卡将不再起作用，直到专用显卡被移除。 3.(P18) Channel I/O requires the use of instructions that are specifically designed to perform（执行）I/O operations. The I/O instructions address（处理）the channel or the channel and device; the channel asynchronously（异步的）accesses all other required addressing and control information. This is similar to
