电类专业英语

Central Processing Unit (CPU) is the brain of a PLC controller. CPU itself is usually one of the microcontrollers. Aforetime these were 8-bit microcontrollers such as 8051, and now these are 16-and 32-bit microcontrollers. Unspoken rule is that you’ll find mostly Hitachi and Fujicu microcontrollers in PLC controllers by Japanese makers, Siemens in European controllers, and Motorola microcontrollers in American ones. CPU also takes care of communication, interconnectedness among other parts of PLC controllers, program execution, memory operation, overseeing input and setting up of an output. PLC controllers have complex routines for memory checkup in order to ensure that PLC memory was not damaged (memory checkup is done for safety reasons).Generally speaking, CPU unit makes a great number of check-ups of the PLC controller itself so eventual errors would be discovered early. You can simply look at any PLC controller and see that there are several indicators in the form. of light diodes for error signalization. System memory (today mostly implemented in FLASH technology) is used by a PLC for a process control system. Aside form. this operating system it also contains a user program translated forma ladder diagram to a binary form. FLASH memory contents can be changed only in case where user program is being changed. PLC controllers were used earlier instead of PLASH memory and have had EPROM memory instead of FLASH memory which had to be erased with UV lamp and programmed on programmers. With the use of FLASH technology this process was greatly shortened. Reprogramming a program memory is done through a serial cable in a program for application development. User memory is divided into blocks having special functions. Some parts of a memory are used for storing input and output status. The real status of an input is stored either as “1”or as “0”in a specific memory bit/ each input or output has one corresponding bit in memory. Other parts of memory are used to store variable contents for variables used in used program. For example, time value, or counter value would be stored in this part of the memory. PLC controller can be reprogrammed through a computer (usual way), but also through manual programmers (consoles). This practically means that each PLC controller can programmed through a computer if you have the software needed for programming. Today’s transmission computers are ideal for reprogramming a PLC controller in factory itself. This is of great importance to industry. Once the system is corrected, it is also important to read the right program into a PLC again. It is also good to check from time to time whether program in a PLC has not changed. This helps to avoid hazardous situations in factory rooms (some automakers have established communication networks which regularly check programs in PLC controllers to ensure execution only of good programs). Almost every program for programming a PLC controller possesses various useful options such as: forced switching on and off of the system input/outputs (I/O lines), program follow up in real time as well as documenting a diagram.

1.英语学术论文的语言风格特点就(知人方能论世) 为什么我们会读不懂SCI上面的文章呢? 第一,由于SCI里面出现的专业词汇一般都是出现在特定领域,一类是一词对应于一意,另外一类则是一词多义。 其次,名词化结构则是另外另外一个普遍出现的现象,可以看到,复合名词,加前缀和后缀,以及省略现象可谓是漫山遍野,因为文体要求行文简洁、表达客观、内容确切、信息量大、强调存在的事实,一般文章不会夹杂着太多主观看法。 最后,大量使用长句和定语从句SCI论文发表中大量使用长句和定语从句,在论证上起到连接信息和强调信息的作用。广泛使用被动语态SCI论文发表中侧重叙事推理,强调客观准确,第一、二人称使用过多,会造成主观臆断的印象。因此尽量使用第三人称叙述,采用被动语态。名词作定语和缩写词使用频繁SCI论文发表中要求结构紧凑、行文简炼,缩写词和名词作定语的频繁使用,增大了信息密度,简化了句型。 如果我们能逆向思维,转换个角度去看文章,如果你要发表一篇SCI论文,你会怎么去构造你的行为,你如何组织你文章的逻辑,特别是用词方面,口语和一些狸语在一般

情况不应该出现在文章中。还有些中式英语也会极大地影响我们的阅读,例如说足球比赛,可不是我们想象中的football match (之前有次演讲说,英语里面不能有2个名词的情况,在此就举了个例子bicycle man),而应该做football play亦作soccer play。 2.翻译是一门艺术,从某种意义上来讲是没有标准答案的。 这里本人想要想要阐述这样一种观点,翻译是一个不断精进的过程,翻译最初的目的即是为了实现语言之间的一个互相沟通,然而不同的人对一句话,应该会有着不同的理解。这也就有了译者极大的自由发挥性,但是译者必须准确理解原文的基础之上的。 有三个字可以高度概括翻译的精髓“信,达,雅”,想必大家都应该听过。”“信”指意义不背原文,即是译文要准确,不歪曲,不遗漏,也不要随意增减意思;同样可以举个例子?This is a pan in my hand (请问如何翻译呢?) “达”指不拘泥于原文形式,译文通顺明白;这里就涉及到一个直译和意译的关系啦,否则就会出现像bicycle

英语专业实习报告

英语专业实习报告 ????实习学校.市二中学,上海市第二中学,自己初中,高中7年的母校,可以说是再熟悉不过,看到大学里对口的学校里有这所的时候,没有丝毫犹豫地就填进了志愿里,也如愿的在母校开始了大学必经的实习阶段,也是别有一番意义的.回学校实习,亲切万分,亲爱的老师们还在,接受教育的学生们却是一张张全新的面孔,想想自己离开学校3年来的进进出出,目前的3个年级都是我毕业后考进市二的学生.学校的操场,小花园,甚至是几间教室,都是充满回忆的地方,接下来实习的日子,走过这些地方的时候,过去的记忆就不断在脑海里回旋. ????初日.我们一行8位同学到达市二后,接待我们的是现任教导主任高萍老师,她向我们简单介绍了下学校目前的状况,以及实习期间需要注意的一些事项.接下来是认识带教老师,我与其他2位同学分到高一,其余5位同学到高二.英语学科的带教老师是王雅芬老师,教学经验丰富,还担任高一的年级组长;班主任唐虹老师,自己高三时,她教过我政治,算是相当熟悉,呵呵.带教老师和班主任都向我们简单介绍了一下所带班级的基本情况.第一天只是熟悉下校园,第二天正式到班级,当时想到就要面对40多个学生,不免还是有点担心和紧张. ????身份.实习老师,是个很特别的存在.还记得第一次被班级里学生叫老师好的时候的那种错愕,渐渐适应,然后自如反应,点头示意.开始的一个礼拜,日渐习惯起学校的生活,仿佛重回高中时代一般,只是是以一种全新的角度来看待学生,以老师的身份来要求自己了,这种感觉挺奇妙的,以往觉得“高高在上”的老师,突然间成了身边的“同事”,作为实习老师,又该以怎样的态度去面对高中的学生?身份的转变,是实习阶段第一个要跨越的坎吧,正确认识自己的身份:带教老师的学生,高中学生的老师. ????高一(X)班.担任实习班主任工作的班级是高一(7)班,高一年级两个理科班之一,与我那时的理科班大为不同,现在理科班的学生不像我们那时那么沉闷,就像班主任唐老师所说,对于老师来说是喜忧参半吧,毕竟调皮的学生太多,比较不容易控制.一进教室就看到教室后的墙壁上贴满了奖状,看的出来这个班级在学校里也是相当活跃的,学校里评选的各个之星,几乎7班也每个都有份.班上同学的性格很活泼,几天相处下来,就建立起了不错的关系,谈谈班级同学,日常琐事,甚至也有同学会来找我解答问题,谈谈理想,也让自己渐渐有了的确是个老师了的觉悟. ????听课.实习的必经阶段,听课不仅能够学习带教老师的教学方法,也能熟悉自己将要教学的班级.高中阶段的英语课程与大学里大不相同,尽管自己以前高中时也上过牛津的教材,现在的教学要求又有新的变化,也因老师的不同,教学方法上有很大的差异.带教的王老师教态相当严谨,备课很充分,听第一节课的时候就觉得整节课规划的很好,让学生知道这节课要完成的内容,就算有突发状况的发生,也能自行控制好时间等等.学校规定的听课是10节左右,自己基本上能去听的课都去了,为的是想了解整个章节上课的完整过程,每个部分都有不同的上课手段和形式,都是值得学习的地方.大学里所学的英语教学法课程,提及不少教学

过程装备与控制工程专业英语翻译6

Reading Material 6 Stainless Steel Stainless steels do not rust in the atmosphere as most other steels do. The term "stainless" implies a resistance to staining, rusting, and pitting in the air, moist and polluted as it is, and generally defines a chromium content in excess of 11 % but less than 30%. And the fact that the stuff is "steel" means that the base is iron. Stainless steels have room-temperature yield strengths that range from 205 MPa (30 ksi) to more than 1725 MPa (250 ksi). Operating temperatures around 750 C (1400 F) are reached. At the other extreme of temperature some stainless steels maintain their toughness down to temperatures approaching absolute zero. With specific restrictions in certain types, the stainless steels can be shaped and fabricated in conventional ways. They can be produced and used in the as-cast condition; shapes can be produced by powder-metallurgy techniques; cast ingots can be rolled or forged (and this accounts for the greatest tonnage by far). The rolled product can be drawn, bent, extruded, or spun. Stainless steel can be further shaped by machining, and it can be joined by soldering, brazing, and welding. It can be used as an integral cladding on plain carbon or low-alloy steels. The generic term "stainless steel" covers scores of standard compositions as well as variations bearing company trade names and special alloys made for particular applications. Stainless steels vary in their composition from a fairly simple alloy of, essentially, iron with 11% chromium, to complex alloys that include 30% chromium, substantial quantities of nickel, and half a dozen other effective elements. At the high-chromium, high-nickel end of the range they merge into other groups of heat-resisting alloys, and one has to be arbitrary about a cutoff point. If the alloy content is so high that the iron content is about half, however, the alloy falls outside the stainless family. Even with these imposed restrictions on composition, the range is great, and naturally, the properties that affect fabrication and use vary enormously. It is obviously not enough to specify simply a "stainless steel.” Classification the various specifying bodies categorize stainless steels according to chemical composition and other properties. However, all the stainless steels, whatever specifications they conform to, can be conveniently classified into six major classes that represent three distinct types of alloy constitution, or structure. These classes are ferritic, martensitic, austenitic, manganese-substituted austenitic, duplex austenitic ferritic, and precipitation-hardening. Each class is briefly described below. (1) Ferrous stainless steels: This class is so named because the crystal structure of the steel is the same as that of iron at room temperature. The alloys in the class are magnetic at room temperature and up to their Curie temperature (about 750 C; 1400 F). Common alloys in the ferrous class contain between 11% and 29% chromium, no nickel, and very little carbon in the wrought condition. (2)Martensitic stainless steels: Stainless steels of this class, which
