外文文献翻译（译成中文2000字左右）： As research laboratories become more automated,new problems are arising for laboratory managers.Rarely does a laboratory purchase all of its automation from a single equipment vendor. As a result,managers are forced to spend money training their users on numerous different software packages while purchasing support contracts for each. This suggests a problem of scalability. In the ideal world,managers could use the same software package to control systems of any size; from single instruments such as pipettors or readers to large robotic systems with up to hundreds of instruments. If such a software package existed, managers would only have to train users on one platform and would be able to source software support from a single vendor. If automation software is written to be scalable, it must also be flexible. Having a platform that can control systems of any size is far less valuable if the end user cannot control every device type they need to use. Similarly, if the software cannot connect to the customer’s Laboratory Information Management System (LIMS) database,it is of limited usefulness. The ideal automation software platform must therefore have an open architecture to provide such connectivity. Two strong reasons to automate a laboratory are increased throughput and improved robustness. It does not make sense to purchase high-speed automation if the controlling software does not maximize throughput of the system. The ideal automation software, therefore, would make use of redundant devices in the system to increase throughput. For example, let us assume that a plate-reading step is the slowest task in a given method. It would make that if the system operator connected another identical reader into the system, the controller software should be able to use both readers, cutting the total throughput time of the reading step in half. While resource pooling provides a clear throughput advantage, it can also be used to make the system more robust. For example, if one of the two readers were to experience some sort of error, the controlling software should be smart enough to route all samples to the working reader without taking the entire system offline. Now that one embodiment of an ideal automation control platform has been described let us see how the use of C++ helps achieving this ideal possible. DISCUSSION C++: An Object-Oriented Language Developed in 1983 by BjarneStroustrup of Bell Labs,C++ helped propel the concept of object-oriented programming into the mainstream.The term ‘‘object-oriented programming language’’ is a familiar phrase that has been in use for decades. But what does it mean? And why is it relevant for automation software? Essentially, a language that is object-oriented provides three important programming mechanisms:
计算机专业英语翻译参考
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. 5.(P21) We many have defined our last generation of computer and begun the era of generationless computers. Even though computer manufacturers 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。 6.(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。 7.(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

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。
