经济管理学院专业英语结课论文

一学习总结 1理论课程学习总结 人说，“走进大学就一只脚踏进了社会”，这句话没说错。上大学之前，我们有三分之二的时间在学校认真学习科学知识，缺乏自理能力，不懂人情世故。而上了大学之后，不仅要学习，还要管理好自己的生活、处理好与同学、老师的关系。所有这些都不是老师和爸妈能教会的，要靠自己在日常生活中不断的学习和总结经验教训。 在大学里，有些人刻苦专研专业知识，希望将来在专业方面有所突破或能继续深造；有些人则在学好功课的基础上，发现了自己某方面的潜力，比如：较强的社交能力、体育比较好等。而大学这样一个宽松的环境正为他们提供了一个实现自我的舞台。因此，在大学里，我们不仅可以更深入的学习科学知识，还可以在业余时间挖掘自身的潜力和增强自身的特长。但不管将来你从事什么工作，首先要学好英语和用好计算机，这是形势所迫，也是现实。随着现代化步伐的加快，计算机已经成为我们进行各项工作的主要工具，而学好英语是用好计算机的基础，以后走上工作岗位，不会英语和计算机，我们将寸步难行。 但有很多同学说，英语很难学，就是学不好。其实并不是不能学好，我认为没有学不会的东西，除非你不去努力或方法不对。说句实在话，学语言确实是一件比较困难的事，尤其是在一个没有相关语言环境的情况下去学。因为学语言包括听，说，读，写四个方面，要想做到这四个方面都强确实不容易。但我们可以先掌握好基础知识，再根据自己以后的发展方向决定在哪个方面进行提高。比如，你决定以后从事软件开发的工作，那你可以多看看这方面的英文版的书籍。 可是，尽管英语是如此的难学，很多同学还是不以为然。许多同学进入大学后就想着如何去玩，觉得初中、高中这六年憋得实在不行了。可是放松也要有限度，不能荒废了学业，难道辛辛苦苦考上大学就是来玩的吗？因此，当我们在享受大学生活给我们带来新鲜和刺激时，不要忘了花点时间去读读单词，看看英语文章。把英语学习当成一种乐趣，而不仅仅是应付学校的考试和通过四六级。 其次，就要说到计算机知识的学习了，对于我们信息管理专业来说，计算机就是我们谋生的工具。首先，我们应学会最基本的使用电脑的操作，如开机、关机、软件的安装、office的使用、电脑的日常维护等。此外，随着科学技术的日新月异的发展，网络在人们的生活中起着越来越重要的作用，不管是日常生活、交友、娱乐还是工作，人们越来越依赖于网络。因此我们还要学会上网，学会利

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
