外文翻译英文原文 Belt Conveying Systems Development of driving system Among the methods of material conveying employed，belt conveyors play a very important part in the reliable carrying of material over long distances at competitive cost．Conveyor systems have become larger and more complex and drive systems have also been going through a process of evolution and will continue to do so．Nowadays，bigger belts require more power and have brought the need for larger individual drives as well as multiple drives such as 3 drives of 750 kW for one belt(this is the case for the conveyor drives in Chengzhuang Mine)．The ability to control drive acceleration torque is critical to belt conveyors’performance．An efficient drive system should be able to provide smooth，soft starts while maintaining belt tensions within the specified safe limits．For load sharing on multiple drives．torque and speed control are also important considerations in the drive system’s design. Due to the advances in conveyor drive control technology，at present many more reliable．Cost-effective and performance-driven conveyor drive systems covering a wide range of power are available for customers’ choices[1]. 1 Analysis on conveyor drive technologies 1．1 Direct drives Full-voltage starters．With a full-voltage starter design，the conveyor head shaft is direct-coupled to the motor through the gear drive．Direct full-voltage starters are adequate for relatively low-power, simple-profile conveyors．With direct fu11-voltage starters．no control is provided for various conveyor loads and．depending on the ratio between fu11-and no-1oad power requirements，empty starting times can be three or four times faster than full load．The maintenance-free starting system is simple，low-cost and very reliable．However, they cannot control starting torque and maximum stall torque；therefore．they are

Lesson One: The Time Message Elwood N, Chapman 新的学习任务开始之际，千头万绪，最重要的是安排好时间，做时间的主人。本文作者提出了7点具体建议，或许对你有所启迪。 1 Time is tricky. It is difficult to control and easy to waste. When you look a head, you think you have more time than you need. For Example,at the beginning of a semester, you may feel that you have plenty of time on your hands, but toward the end of the term you may suddenly find that time is running out. You don't have enough time to cover all your duties (duty), so you get worried. What is the answer? Control! 译：时间真是不好对付，既难以控制好，又很容易浪费掉，当你向前看时，你觉得你的时间用不完。例如，在一个学期的开始，你或许觉得你有许多时间，但到学期快要结束时，你会突然发现时间快用光了，你甚至找不出时间把所有你必须干的事情干完，这样你就紧张了。答案是什么呢？控制。 2 Time is dangerous. If you don't control it, it will control you. I f you don't make it work fo r you, it will work against you. So you must become the master of time, not its servant. As a first-year college student, time management will be your number one Problem. 译：时间是危险的，如果你控制不了时间，时间就会控制你，如果你不能让时间为你服务，它就会起反作用。所以，你必须成为时间的主人，而不是它的奴仆，作为刚入学的大学生，妥善安排时间是你的头等大事。 3 Time is valuable. Wasting time is a bad habit. It is like a drug. The more time you waste,the easier it is to go on wasting time. If seriously wish to get the most out of college, you must put the time message into practice. 译：时间是珍贵的，浪费时间是个坏习惯，这就像毒品一样，你越浪费时间，就越容易继续浪费下去，如果你真的想充分利用上大学的机会，你就应该把利用时间的要旨付诸实践。 Message1. Control time from the beginning. 4 Time is today, not tomorrow or next week. Start your plan at the Beginning of the term. 译：抓紧时间就是抓紧当前的时间，不要把事情推到明天或是下周，在学期开始就开始计划。 Message2. Get the notebook habit. 5 Go and buy a notebook today, Use it to plan your study time each day. Once a weekly study plan is prepared, follow the same pattern every week with small changes. Sunday is a good day to make the Plan for the following week.

Unit 1 Changes in the Way We Live 在美国，不少人对乡村生活怀有浪漫的情感。许多居住在城镇的人梦想着自己办个农场，梦想着靠土地为生。很少有人真去把梦想变为现实。或许这也没有什么不好，因为，正如吉姆·多尔蒂当初开始其写作和农场经营双重生涯时所体验到的那样，农耕生活远非轻松自在。但他写道，自己并不后悔，对自己作出的改变生活方式的决定仍热情不减。 Mr. Doherty Builds His Dream Life Jim Doherty 有两件事是我一直想做的――写作与务农。如今我同时做着这两件事。作为作家，我和E·B·怀特不属同一等级，作为农场主，我和乡邻也不是同一类人，不过我应付得还行。在城市以及郊区历经多年的怅惘失望之后，我和妻子桑迪终于在这里的乡村寻觅到心灵的满足。这是一种自力更生的生活。我们食用的果蔬几乎都是自己种的。自家饲养的鸡提供鸡蛋，每星期还能剩余几十个出售。自家养殖的蜜蜂提供蜂蜜，我们还自己动手砍柴，足可供过冬取暖之用。这也是一种令人满足的生活。夏日里我们在河上荡舟，在林子里野餐，骑着自行车长时间漫游。冬日里我们滑雪溜冰。我们为落日的余辉而激动。我们爱闻大地回暖的气息，爱听牛群哞叫。我们守着看鹰儿飞过上空，看玉米田间鹿群嬉跃。但如此美妙的生活有时会变得相当艰苦。就在三个月前，气温降

到华氏零下30度，我们辛苦劳作了整整两天，用一个雪橇沿着河边拖运木柴。再过三个月，气温会升到95度，我们就要给玉米松土，在草莓地除草，还要宰杀家禽。前一阵子我和桑迪不得不翻修后屋顶。过些时候，四个孩子中的两个小的，16岁的吉米和13岁的埃米莉，会帮着我一起把拖了很久没修的室外厕所修葺一下，那是专为室外干活修建的。这个月晚些时候，我们要给果树喷洒药水，要油漆谷仓，要给菜园播种，要赶在新的小鸡运到之前清扫鸡舍。在这些活计之间，我每周要抽空花五、六十个小时，不是打字撰文，就是为作为自由撰稿人投给报刊的文章进行采访。桑迪则有她自己繁忙的工作日程。除了日常的家务，她还照管菜园和蜂房，烘烤面包，将食品装罐、冷藏，开车送孩子学音乐，和他们一起练习，自己还要上风琴课，为我做些研究工作并打字，自己有时也写写文章，还要侍弄花圃，堆摞木柴、运送鸡蛋。正如老话说的那样，在这种情形之下，坏人不得闲――贤德之人也歇不了。我们谁也不会忘记第一年的冬天。从12月一直到3月底，我们都被深达5英尺的积雪困着。暴风雪肆虐，一场接着一场，积雪厚厚地覆盖着屋子和谷仓，而室内，我们用自己砍伐的木柴烧火取暖，吃着自家种植的苹果，温馨快乐每一分钟。开春后，有过两次泛滥。一次是河水外溢，我们不少田地被淹了几个星期。接着一次是生长季节到了，一波又一波的农产品潮涌而来，弄得我们应接不暇。我们的冰箱里塞满了樱桃、蓝莓、草莓、芦笋、豌豆、青豆和玉米。接着我们存放食品罐的架子上、柜橱里也开始堆

2、应力和应变在任何工程结构中独立的部件或构件将承受来自于部件的使用状况或工作的外部环境的外力作用。如果组件就处于平衡状态,由此而来的各种外力将会为零,但尽管如此,它们共同作用部件的载荷易于使部件变形同时在材料里面产生相应的内力。有很多不同负载可以应用于构件的方式。负荷根据相应时间的不同可分为: (a)静态负荷是一种在相对较短的时间内逐步达到平衡的应用载荷。 (b)持续负载是一种在很长一段时间为一个常数的载荷, 例如结构的重量。这种类型的载荷以相同的方式作为一个静态负荷; 然而,对一些材料与温度和压力的条件下,短时间的载荷和长时间的载荷抵抗失效的能力可能是不同的。 (c)冲击载荷是一种快速载荷(一种能量载荷)。振动通常导致一个冲击载荷, 一般平衡是不能建立的直到通过自然的阻尼力的作用使振动停止的时候。 (d)重复载荷是一种被应用和去除千万次的载荷。 (e)疲劳载荷或交变载荷是一种大小和设计随时间不断变化的载荷。上面已经提到，作用于物体的外力与在材料里面产生的相应内力平衡。因此,如果一个杆受到一个均匀的拉伸和压缩，也就是说, 一个力,均匀分布于一截面,那么产生的内力也均匀分布并且可以说杆是受到一个均匀的正常应力,应力被定义为应力==负载 P /压力 A, 因此根据载荷的性质应力是可以压缩或拉伸的,并被度量为牛顿每平方米或它的倍数。如果一个杆受到轴向载荷，即是应力，那么杆的长度会改变。如果杆的初始长度L和改变量△L已知，产生的应力定义如下: 应力==改变长△L /初始长 L 因此应力是一个测量材料变形和无量纲的物理量 ,即它没有单位;它只是两个相同单位的物理量的比值。一般来说,在实践中,在荷载作用下材料的延伸是非常小的, 测量的应力以*10-6的形式是方便的, 即微应变, 使用的符号也相应成为ue。从某种意义上说，拉伸应力与应变被认为是正的。压缩应力与应变被认为是负的。因此负应力使长度减小。当负载移除时，如果材料回复到初始的，无负载时的尺寸时，我们就说它是具有弹性的。一特定形式的适用于大范围的工程材料至少工程材料受载荷的大部分的弹性, 产生正比于负载的变形。由于载荷正比于载荷所产生的压力并且变形正比于应变, 这也说明,当材料是弹性的时候, 应力与应变成正比。因此胡克定律陈述, 应力正比于应变。这定律服从于大部分铁合金在特定的范围内, 甚至以其合理的准确性可以假定适用于其他工程材料比如混凝土，木材，非铁合金。当一个材料是弹性的时候，当载荷消除之后，任何负载所产生的变形可以完全恢复,没有永久的变形。

Unit1 The Burden of Womanhood Too often in the Third World, a female?s life is hardly worth living. By: John Ward Anderson & Molly Moore 女人的负担往往在第三世界，女性的生活几乎是不值得活的。约翰.沃德.安德森和莫莉.摩尔 1.When Rani returned home from the hospital cradling her newborn daughter, the men in the family slipped out of her mud hut while she and her mother-in-law mashed poisonous oleander seeds into a dollop of oil and dropped it into the baby?s throat. As soon as darkness fell, Rani crept into a nearby field and buried her baby girl in a shallow, unmarked grave next to a small stream. 当拉尼抱着她刚出生的女儿从医院回到家时，男人们溜出了她的土屋，她和她的婆婆将有毒的夹竹桃种子捣碎成一团油，并将其塞到婴儿的喉咙里。夜幕一降临，拉尼就蹑手蹑脚地来到附近的一块土地，将她的女婴埋在一条小溪浅旁边的一个不深的、没有标记的坟墓内。 2.“I never felt any sorrow,” Rani, a farm laborer with a weather-beaten face, said through an interpreter. “There was a lot of bitterness in my heart toward the baby because the gods should have given me a son.” “我从来没有感到任何悲哀”，脸部饱经风霜的拉尼通过翻译说，“我的心对孩子充满了辛酸，因为神本应该赐予我一个儿子”。 3.Each year hundreds and perhaps thousands of newborn girls in India are murdered by their mothers simply because they are female. Some women believe that sacrificing a daughter guarantees a son in the next pregnancy. In other cases, the family cannot afford the dowry that would eventually be demanded for a girl?s marriage. 在印度每年有数百甚至数千名新生女婴被他们的母亲谋杀，只因为他们是女孩。有些妇女认为，牺牲一个女儿将保证下次怀孕是儿子。在其他情况下，家庭买不起女孩结婚时所需的嫁妆。 4.And for many mothers, sentencing a daughter to death is better than condemning her to life as a woman in the Third World, with cradle-to-grave discrimination, poverty, sickness and drudgery. 对于很多母亲而言，判处女儿死刑胜过让她在第三世界作为一个女人生活，经历一辈子的歧视、贫困、疾病和劳苦。

. 4、工程机械概述 As we look around us we see a world full of“things”: machines, devices, tools; things that we have designed, built,and used; things made of wood, metals,ceramics, and plastics.We know from experience that some things are better than others;they last longer, cost less, are quieter, look better, or are easier to use. ; ; 情况 . Ideally, however, every such item has been designed according to some set of “functional requirements”as perceived by the designers—that is, it has been designed so as to answer the question,“Exactly what function should it perform?” In the world of engineering, the major function frequently is to support some type of loading due to weight, inertia, pressure, etc. 的 From the beams in our homes to the wings of an airplane, there must be an appropriate melding of materials,dimensions, and fastenings to produce structures that will perform their functions reliably for a reasonable cost over a reasonable
