专业英语大作业 一:英译汉 翻译范围TCP/IP Illustrated, V olume 1: The Protocols 5.1~5.5 15.1~15.2 第5章RARP:逆地址解析协议 5.1简介 5.2 RARP报文格式 5.3 RARP示例 5.4 RARP服务的设计 5.5小结 练习 5.1简介 一个拥有本地磁盘的系统通常是从磁盘文件读取配置文件中获取其IP地址。但一个没有磁盘的系统,如X终端或无盘工作站,需要一些其它方式去获得其IP地址。 每个系统在网络上都有一个唯一的硬件地址,由网络接口的制造商分配。 RARP的原则是无盘系统从接口卡上读取其独特的硬件地址,并发送RARP请求(网络上的广播帧)要求别人对无盘系统的IP地址(使用RARP回应)进行应答。 虽然这个概念很简单,执行往往比ARP更难,在本章后面会描述其原因。 RARP的正式规范是RFC 903。 5.2 RARP报文格式 RARP报文的格式几乎与ARP报文是相同的(图4.3)。唯一的区别是,RARP 的请求或应答帧类型为0×8035,并且在操作层RARP请求值为3、RARP应答值为4。 图4-3 ARP在网络上请求与应答报文的格式 与ARP一样,RARP服务器请求是广播和RARP应答通常是单播。 5.3 RARP示例 在我们的网络,我们可以强制sun主机从网络引导,而不是它的本地磁盘。 如果我们在主机bsdi上运行RARP服务器和tcpdump,我们得到如图5.1所示的输出。我们使用-e参数去标记tcpdump的打印硬件地址:

图5.1 RARP请求和应答。 该RARP请求是广播(1号线)的,第2行的RARP应答是单播的。第2行的输出,“at sun”,意味着RARP应答包含了主机sun(140.252.13.33)的IP地址。 在第3行,我们看到,一旦sun接收其IP地址,它会发出一个TFTP读请求(RRQ)的文件8CFCOD21.SUN4C。(TFTP是简单文件传输协议,我们在第15章进行详细描述)。在文件名中的8个十六进制数字是sun主机的IP地址140.252.13.33的十六进制表示形式。这是在RARP应答中返回的IP地址。该文件名的其余部分,后缀SUN4C表示系统正在引导的类型。 Tcpdump表示第3行是一个长度为65的IP数据报,而不是一个UDP数据报(实际上它确实是),因为我们运行tcpdump命令使用-e参数,看硬件级别的地址。另一点,在图5.1要注意的是在第2行的以太网帧的长度似乎比最小较短(我们所说的是在4.5节60字节)。原因是我们的系统,该系统上运行的tcpdump 发送该以太网帧(BSDI)。该应用程序rarpd,写42字节到BSD分组过滤器装置(14字节的以太网报头和28字节的RARP应答),这是什么的tcpdump收到的副本。但以太网设备驱动程序垫这个短帧的最小尺寸为传输(60 )。如果我们在另一个系统上已经运行的tcpdump ,长度会是60。 我们可以看到在这个例子,当这种无盘系统接收在RARP应答它的IP地址,它会发出一个TFTP请求来读取一个引导映像。在这一点上,我们不会进入其他详细介绍无盘系统是如何引导自己。(第16章介绍了使用RARP ,BOOTP和TFTP无盘X终端的引导顺序。) 图5.2表示出了如果有在网络上没有RARP服务器所得到的数据包。每个数据包的目的地址为以太网的广播地址。以太网地址跟随的是目标硬件地址,并按照发送端的硬件地址发送。

《自动化专业英语》翻译大作业 所选文字出处:选自论文《PLC的发展和应用》 班级:学号:姓名:成绩: PLC全名为可编程控制器,定义是种数字运算操作的电子系统,专为在工业环境应用而设计的,主要结构由电源,中央处理单元,存储器,输入输出接口电路,功能模块,通信模块组成。PLC具有通用性强、使用方便、适应面广、抗干扰性强、编程简单等特点,在军事、国防、航空航天、交通、工业生产中的地位,在可预见的将来中是无法取代的。PLC有很多流派,我国的PLC研发、生产和应用发展很快,尤其在应用方面更为突出。 PLC的发展历程和主要流派 在工业生产过程中,大量的开关量顺序控制,它按照逻辑条件进行顺序动作,并按照逻辑关系进行连锁保护动作的控制,及大量离散量的数据采集。传统上,这些功能是通过气动或电气控制系统来实现的。1968年美国GM(通用汽车)公司提出取代继电气控制装置的要求,第二年,美国数字公司研制出了基于集成电路和电子技术的控制装置,首次采用程序化的手段应用于电气控制,这就是第一代可编程序控制器,称Programmable Controller(PC)。个人计算机(简称PC)发展起来后,为了方便,也为了反映可编程控制器的功能特点,可编程序控制器定名为Programmable Logic Controller(PLC),现在,仍常常将PLC简称PC。PLC的定义有许多种。国际电工委员会(IEC)对PLC的定义是:可编程控制器是一种数字运算操作的电子系统,专为在工业环境下应用而设计。它采用可编程序的存贮器,用来在其内部存贮执行逻辑运算、顺序控制、定时、计数和算术运算等操作的指令,并通过数字的、模拟的输入和输出,控制各种类型的机械或生产过程。可编程序控制器及其有关设备,都应按易于与工业控制系统形成一个整体,易于扩充其功能的原则设计。上世纪80年代至90年代中期,是PLC发展最快的时期,年增长率一直保持为30~40%。在这时期,PLC在处理模拟量能力、数字运算能力、人机接口能力和网络能力得到大幅度提高,PLC逐渐进入过程控制领域,在某些应用上取代了在过程控制领域处于统治地位的DCS系统。在世界上200多家PLC厂商,400多品种的PLC产品大体可以按地域分成三个流派:一个流派是美国产品,一个流派是欧洲产品,还有一个流派是日本产品。同一地区的产品相互借鉴的比较多,相互影响比较大,技术参透比较深,面临的主要市场相同,拥护要求接近,这一切就使得同一地域的PLC产品表现出比较多的相似性。美国PLC技术的形成与欧洲PLC技术的形成是在相互隔离的情况下,独自研究开发获得的,因此美国的PLC产品与欧洲的PLC产品常表现出来明显的差异性。日本的PLC技术是由美国引进的,因此日本的产品对美国的产品有一定的继承性。世界上比较先进的PLC生产厂家有德国的的西门子、日本的三菱、美国的A-B公司等等。

lesson 10 P1 P2 The mould designer is frequently confronted with a component design that incorporates a recess or projection which prevents the simple removal of the molding from the mould. The mould design for this type of component is inevitably more complex than for the in line of draw component, as it necessitates the removal of that part of the impression which forms the undercut prior to ejection ①. The splits can be incorporated in the mould design in several ways. The designer considers more complex systems where the splits are retained on the mould plate and actuated automatically. There are two basic designs: sliding and angled-lift splits. In both designs there are moving parts and it is necessary to arrange for (i) guiding the splits in the desired direction, (ii) actuating the splits, and (iii) securely locking the splits in position prior to the material being injection into the moul d②. 模具设计师经常面临的一个组成部分的设计,包括凹槽或投影,防止简单去除成型模具。因为脱模前要先抽出形成侧型芯的那部分型腔,这类零件的模具设计比直接脱模的零件复杂的多。 滑块可纳入模具设计的几种方法。设计师认为,更复杂的系统,滑块将自动保留并驱动在模板中。有两个个基本的设计思路:滑动和斜滑块。 在两者的设计中都有活动零件,而且有必要安排:沿着正确方向导向滑块,驱动滑块,在材料注射进模具之前安全地锁紧滑块。 Lesson 1 The injection molding and machine 1.1The injection molding 2Injection molding is principally used for the production of the thermoplastic parts, although some progress has been made in developing a method for injection molding some thermosetting materials. The problem of injecting a melted plastic into a mold cavity from a reservoir of melted material has been extremely difficult to solve for thermosetting plastics which cure and harden under such conditions within a few minute s①. The principle of injection molding is quite similar to that of die-casting. The process consists of feeding a plastic compound in powdered or granular from a hopper through metering and melting stages and then injecting it into a mol d②. After a brief cooling period, the mold is opened and the solidified part ejected. Injection-molding machines can be arranged for manual operation, automatic single-cycle operation, and full automatic operation. The advantage of injection molding are: (i) a high molding speed adapted for mass production is possible; (ii) there is a wide choice of thermoplastic materials providing a variety of useful properties; (iii) it is

Hoboken, NJ Wiley Interscience; 2006.$150.00. The last decade has been a remarkably productive and interesting time for those vision scientists who study the retinal structure of the human eye. In great part this has been made possible by the introduction of a technological advance in their field that has dramatically increased their ability to resolve the fine detail of the retina. This advance is the incorporation of adaptive optics into their imaging systems and by so doing, to almost completely remove the natural optical aberrations of the eye. Those involved in this field are comparatively few in number, and there are a limited number of centers throughout the world equipped to conduct this research. However, there is great interest in their findings throughout the large field of vision scientists and eye care professionals. So, a number of pioneers in the field of adaptive optics for vision science thought to put together a book “to equip engineers, scientists, and clinicians with the basic concepts, engineering tools, and tricks of the trade required to master adaptive optics-related application in vision science and ophthalmology.”Adaptive Optics in
