Cars in America(美国的汽车)Cars in AmericaCars are an important part of lifein the United S The car made the UnitedStatesanationon Andit helped to make the United States what it is There are three main reasons why the car became so popular in the United S First of all the country is a huge one and Americans like to move around in The cars provide the most comfortable and cheapest form of The second reason that cars are popular is the fact that the United States never really developed an efficient and inexpensive form of public Long-distance trains have never been as common in the United States as they are in other parts of the Nowadays there is a good system of air service provided by But it is too expensive to be used The third reason is the most important one， The American spirit of independence is what really made cars Americans don't like to wait for a bus， or a train or even a They don't like to have to follow an exact And the freedom a car gives them is what Americans want most to The decrease of gas supplies has caused a big problem for A But the answer will not be a bigger system of public The real solution will have to be a new kind of car， one that does not use so much 美国的汽车汽车是美国生活的重要组成部分。汽车使得美国成为轮子上的国家，它也帮助美国成为现在的样子。汽车在美国如此盛行有三个主要原因。首先这个国家地域辽阔，而美国人喜欢在其间来回走动。汽车提供了最舒适最便宜的交通方式。汽车如此盛行的第二个原因是美国从未真正发展过有效廉价的公共交通这一事实。美国的长途火车从未像世界上其它地方那么普及。如今飞机提供了空中服务的良好体系。但是飞机太贵了，不能频繁使用。而第三个原因是最为重要的。美国人的独立精神是使得汽车盛行的真正原因。美国人不喜欢等公共汽车、火车甚至飞机。他们不喜欢必须遵循精确的时间表。汽车给予他们的自由正是美国人最想得到的。汽油供给的减少已经给美国人带来了巨大的问题。但答案不是发展更大型的公交体系。真正的解决方式必须是一种新型的汽车，那种不需要使用很多燃料的汽车。Car PollutionEach year there is an increasing number of cars on the roads as millions of new cars are One out of six Americans works at making cars， driving trucks， building roads or filling up Americans couldn't live without cars!Most Americans would find it hard to imagine life without a However， some have realized the serious problem of air pollution caused by The polluted air becomes poisonous and dangerous to One way to get rid of the polluted air is to make a car without But to build a clean car is easier said than Progress in this field is Another way is to replace car engines with something Inventors are now working on steam cars as well as electric Many makers believe that it will take years to develop a practical model for To prevent the world from being polluted by cars， we have to make some changes in our Americans， for example， have to cut down on the number of their total They are encouraged to use bicycles， which are thought to help keep the air But this change does not come A large number of workers may find themselves without jobs if a car factory cioses Thus the problem of air pollution would become less important than that of Although cars have led us to a better life， they have also brought us new 汽车污染上路的汽车数量逐年增长，同时，每年都会生产出几百万辆新车。在美国，每六个人中就有一个从事与汽车相关的工作：造车、开车、修路、加油等等。离开汽车，美国人无法生活!大部分美国人简直无法想象没有车的生活会是什么样子。但是一些人也已经意识到汽车造成的空气污染已成为严重的问题。被污染的空气具有毒性，并且危害健康。解决空气污染的方法之一就是制造无污染汽车。但是生产清洁汽车说来容易做来难。目前，这一领域的进展十分缓慢。另一个方法就是使用其他东西替代汽车发动机。发明家正在研制蒸汽汽车和电车。但是许多厂家认为我们可以使用的实用型汽车的诞生可能还需要几年时间。要想阻止全球化的汽车污染，我们需要对自己的生活方式做出适当的改变。例如，在美国，需要缩减汽车总量。鼓励人们使用有助空气清洁的自行车。但这种改变不能一蹴而就。一旦汽车工厂关闭，就会有大量工人失去工作。与失业相比，空气污染似乎就不再那么重要了。尽管汽车为我们带来了更加舒适的生活，同时，它也带来了新的问题。

How Manual Transmissions Work by Marshall Brain If you drive a stick-shift car， then you may have several questions floating in your How does the funny "H" pattern that I am moving this shift knob through have any relation to the gears inside the transmission? What is moving inside the transmission when I move the shifter? When I mess up and hear that horrible grinding sound， what is actually grinding? What would happen if I were to accidentally shift into reverse while I am speeding down the freeway? Would the entire transmission explode? In this article， we'll answer all of these questions and more as we explore the interior of a manual Cars need transmissions because of the physics of the gasoline First， any engine has a redline -- a maximum rpm value above which the engine cannot go without Second， if you have read How Horsepower Works， then you know that engines have narrow rpm ranges where horsepower and torque are at their For example， an engine might produce its maximum horsepower at 5，500 The transmission allows the gear ratio between the engine and the drive wheels to change as the car speeds up and slows You shift gears so the engine can stay below the redline and near the rpm band of its best Photo courtesy DaimlerChrysler Mercedes-Benz Actros， manual See more transmission Ideally， the transmission would be so flexible in its ratios that the engine could always run at its single， best-performance rpm That is the idea behind the continuously variable transmission (CVT) A CVT has a nearly infinite range of gear In the past， CVTs could not compete with four-speed and five-speed transmissions in terms of cost， size and reliability， so you didn't see them in production These days， improvements in design have made CVTs more The Toyota Prius is a hybrid car that uses a CVT The transmission is connected to the engine through the The input shaft of the transmission therefore turns at the same rpm as the engine

The lighter drive 更轻便的驾驶理念Electric cars made from carbon fibre will be safer and go farther 电瓶汽车+碳纤维材料=安全，耐用They look safe in thereMARK WEBBER has a lot to thank tiny strands of carbon When his Formula 1 car cartwheeled in a spectacular 306kph (190mph) crash at the recent Valencia Grand Prix， what helped him to escape unscathed was the immensely strong carbon-fibre “tub” that racing drivers now sit Carbon fibre is an expensive alternative to making things in steel or aluminium， but besides being extremely strong it is also very It is found in high-performance parts， like aircraft wings， bits of supercars and the frames of pricey mountain But if work by Germany’s BMW proves successful， it could also become the material of choice to mass-produce electric 6月，F1瓦伦西亚大奖赛发生了惊人一幕：以每小时306公里（190英里）行驶在赛道上的马克�6�1韦伯发生了严重的翻车事故。奇迹的是，韦伯本人毫发无伤。奥妙之处就在于当下流行于F1的——碳纤维底座。虽然与铁，铝相比，它的造价较高，但是抗压及轻便性都远远好于铁和铝。目前，炭纤维材料还大多使用在高精度领域，如飞机机翼，F1赛车，或是私人山地车等。不过这一传统观念可能会被宝马公司打破，一旦试验成功，那么碳纤维就可以率先广泛应用在电动汽车领域。The Bavarian carmaker plans to launch a new plug-in electric car in It will be one of the first designed from scratch to use an electric motor rather than being converted from an existing Reducing the weight of this four-seater car， known as the Megacity concept， will be crucial to improving its performance and So BMW is planning to use no steel at The Megacity will be built as two modules: an aluminium chassis will contain the electric drive-system and battery， and a body made almost entirely of carbon fibre will be fitted onto 德国汽车制造商正计划将在2013年推出一款电瓶可拆卸式环保车。这并不是从现有车型改装而来，而是设计师卧薪尝胆的一次全新尝试。更轻便的4人坐驾，完全符合现代城市环保理念，这款“无铁”车型的设计，彰显出了它的与众不同与理念上的更新换代。但是这样一个设想目前还处在起步阶段，或许成功的那天，汽车铝制底盘上充电驾驶装置与设备，及全身碳纤维的设计工艺，能够更好的诠释大城市的环保概念。Carbon fibre is 30% lighter than aluminium and 50% lighter than The fibres are extremely tear- When woven into a lattice structure and impregnated with resin they can produce a part that is stronger than The trouble is the process is labour-intensive and slow， not least because components may have to be cured for hours under pressure in massive ovens called For carmakers， used to stamping out steel body-parts in a few seconds， this has ruled out carbon fibre for high-volume BMW， however， aims to change 碳纤维比铝轻便30%，是铁的50%。同时，由于纤维具有极强的抗断裂性，再融入树脂形成晶体结构后，那么它的强度就要超过铁。但是这道工序属于劳动密集型，效率相对较低，以前车用铁制品的切割仅需要几秒钟时间就能完成，而现在则需要在高压炉内高温锻造几个小时，因此，大量生产碳纤维的可能性不高。不过，宝马公司目前也正在试图改变这一情况。Its production line starts with a so-called precursor: a fibre spun from a This is carbonised by heating it in multiple stages to leave individual carbon fibres just seven microns (007 millimetres) Around 50，000 of these fibres are bundled together into a yarn which is then made into a This can be cut and handled like a Strips of fabric are then overlaid to align their fibres in such a way to maximise their load-bearing characteristics as required—in effect tailoring components like a bespoke 现在，宝马生产线守开先河，将聚合体加工成纤维状，这个碳化过程需要在高温下进行几道工序，最后产生的碳纤维厚度只有7微米（007毫米）。然后，大概将5000根这样的纤维拧成一股就成了纤维织物，再将这样的纤维根据它的陌生能力将它切割成最合适的尺寸，实际上，这个步骤与量体裁衣有异曲同工之妙。Along come the robots 自动机将助一臂之力BMW uses molds， heat and pressure to produce contours in the Resin is then injected into the molds to bond the fibres How the resin flows through the fibres is crucial; it has to be done quickly and leave no area untreated before it starts to A release agent in the resin migrates to the surface to prevent the component sticking in the The whole process， which can be handled by robots， is completed in 然后，再利用模具与高温将纤维织物打造成型。首先，将树脂注入模具粘合纤维，这里有两个细节非常关键，一是动作要快不能拖泥带水，二是在没有粘合之前确保模具内的树脂流向均匀。树脂中混有的隔离剂此时发挥功效，避免了纤维与模具发生粘连。整道工序，在自动仪器的协助下，仅需几分钟便可完成。The resulting carbon-fibre parts are bonded together to construct the body of the Besides their lightness， BMW’s experimental vehicles have exceeded expectations in crash tests， says the During front- and rear-impact-tests the aluminium chassis crumples to absorb energy， but leaves the rigid carbon-fibre passenger compartment Even extreme side-impacts protected the crash dummies and the battery (automatically switched off when the airbags trigger) In many cases crash damage is reparable by cutting out broken sections of carbon fibre and bonding in new 此时的碳纤维就可以应用于汽车制造。宝马公司声称：除了超轻便的特性之外，碳纤维的抗挤压能力也令人惊叹。在对车头车尾抗冲击测试中发现，一方面是铝制底盘受到挤压而变形，缓冲了部分能量，而坚硬的碳纤维能够保证车身安然无恙。即使是侧面来的强力冲击，也能够有效保护车厢内假人模型及电瓶毫发无伤（当然，气囊装置启动电瓶能够自动断电）。即便是车身有所受损，也不用担心，切割掉受损部分再粘合上新部件，完全可以让车体恢复原状。At some point， however， carbon-fibre cars will be Steel and aluminium is easy to recycle， but carbon fibre is Carmakers are working with aerospace firms on ways to do BMW has pioneered a process to reuse offcuts by breaking them up with heat to turn them back into raw This can be used to make composites with about half the strength of new carbon 铝的回收再利用技术已经非常成熟，但是从某角度来说，碳纤维这方面的技术还有待研究。目前，制造商正和宇宙空间机构合作，试图填补这一空白。眼下，处理碳纤维“边脚料”最先进的方法还是来自宝马公司，他们通过高温分解，能够使之退回成未加工状态。通过此种方法生产出的复合材料也具有碳纤维一半的硬度。Another advantage of a carbon-fibre body is that it will not So， apart from the battery wearing out in ten years or so， electric cars could last for decades (electric motors need little servicing) This will make it even harder for car designers to persuade those driving electrically to trade in their rustless， tough-as-old-boots vehicles for a new 碳纤维的另一优势在于不易腐蚀，如果不考虑电瓶10年左右的使用寿命，这种碳纤维电瓶汽车可以使用长达几十年（当然马达还是需要检修的）。与结实耐穿的靴子让人不忍丢弃一样，当设计理念再有突飞猛进的发展时，如何让使用者放弃碳纤维电瓶汽车，设计者可要好好动一番脑筋喽。英文附带汉语拼音，希望对你有所帮助。

汽车与人们日常、汽车与科技、经济、社会发展的关系　　汽车提高了速度，使人们的时间变得越来越快，加快了生活节奏和事件的发生，增加了对人们的心理的刺激，带了各种生活压力，导致现代社会心理的疲惫与紊乱。。　　还是古代好啊，生活节奏很慢，人们有充足的时间进行思考。。　　效率与压力并存，关系就是大大增加了文明之间交流的频度和广度。　　汽车缩小了时间上的距离，拉近了空间上的距离。　　汽车能给我们带来很多方便，现在汽车的价值也有很多档次，一切都跟我们的社会在不断的进步，科技高速不发展分不开，但私家车不段增加，我们的能源就会加速的减少，但到目前为止还没有真正的一种能够代替石油的能源，汽车不断增加，有利也有弊，我们要用全面的眼光看待这个问题，不能盲目　　汽车是改变世界的机器用是作为人们的代步工具有了汽林的喜剧小品中领略到老爷车的现代社会，汽车已经和人类的车，人类的自由活动半径大大增加笨拙可爱之处，又可以从现代电影生活密不可分了。　　汽车制造是大规模生产的行业，具有规模经济效应　　社会对汽车不断增长的要求，促使汽车工业人日益繁荣。一辆汽车有上万个零件，由钢铁、有色金属、塑料、橡胶、玻璃、纺织品、木材、涂料等繁多材料制成；应用冶炼、锻造、锻压、机械加工、焊接、装配、涂装等许多工艺技术制成；涉及冶金、机械制造、化工、电子、电力、石油、轻工等部门，汽车的销售和营运还涉及金融、商业、运输、旅游、服务等第三产业。可以断言，没有哪个行业与汽车完全无关。汽车业是一个关联度非常大的产业，汽车产业自身发展的同时，还可以带动约150多个上下游产业，从而促进城市经济的发展。此外汽车工业也给社会带来许多机会----日本的汽车制造、销售、营运等行业职工占全国就业人数的1/9，美国和德国的这个比例更高，占1/6。汽车工业的发展无疑回促进个行业的繁荣兴旺，带动整个国民经济的发展。汽车工业一是经济利益很高的产业。在发达国家中，许多著名的汽车企业举足轻重，在世界500强企业的排行榜中均名列前茅，这些国家汽车工业的产值约占国民经济总产值的7%～8%，占机械工业总产值的30%，其实力足以左右国民经济的动向。因此，世界各各发达国家几乎无一例外地把汽车工业作为国民经济的支柱产业。　　我国的汽车工业起步较晚，1953年7月15日第一汽车制造厂在长春动工兴建。1956年10月，第一汽车制造厂开工生产，结束了我国不能制造汽车的历史。1953～1958年是中国汽车产业的创建阶段，长春第一汽车制造厂的建成是这一阶段的标志。这一阶段的特点为建设工作是在原苏联的全面援助下进行的，产品由苏联引进，工艺流程由苏联设计，主要设备由苏联提供，连厂房设计也是由苏联方面承担的。1968年第二汽车制造厂在湖北十堰动工兴建，1975年投产。这个阶段的汽车制造厂及其主要产品由于依赖国家提供原材料和报销全部产品，汽车企业“缺重少轻”、“轿车基本空白”的缺陷后来又因为文革的原因，汽车产量停滞不前。1958～1984 年是中国汽车产业的第二阶段。1958年左右，中苏关系恶化。中国汽车产业与其他经济部门一起进入自力更生的时期。在初步形成了自己的基础工业之后，我国各地纷纷仿造和试制了多款汽车，逐渐形成了几个较有规模的汽车制造厂。改革开放以后，我国汽车行业逐渐从计划经济走向市场经济，开始的蓬勃发展时期。通过引进先进技术和整车项目，已经建立了完整的汽车工业体系，随着国民经济的蓬勃发展和生活水平的提高，对汽车的需求愈来愈旺盛，中国迅速跃升为巨大的汽车市场。我国的汽车产量已跻身于世界生产大国的前列。但是，我国还不是汽车工业强国，我国的汽车工业水平仍然落后，汽车企业多而分散，竞争力不强，不能与汽车工业迅猛发展的形势相适应。　　首先，基于相关行业对汽车工业的作用，由依附、被动到今天走到“台前”，是一种历史进步，汽车业界就不应该总是抱怨“环境不好”，而应该树立一种“在困境中培养坚强”的积极心态。这对整个汽车产业链的发展都是必要的，有益的。　　其次，汽车媒体和专家们由此可以摆脱原有思维惯性，不再“就汽车说汽车”，而要从多方面、多角度、多侧面地研究如何迎接汽车社会的到来？如何认识汽车与汽车文化的关系？如何推动汽车与社会的可持续发展？汽车的普及和与之相关产业的发展将会给经济和社会可持续发展带来什么样的机遇和挑战？怎样促进经济和社会各项事业的协调发展？汽车进入更多普通市民生活后对城市建设和城市管理提出了哪些新要求？具体有哪些改良和改革措施？汽车文化的魅力将如何冲击或影响人们生活方式的改变？等等等等。否则，仅是在汽车降价呀、新车上市呀、怎样修车呀上面打转转，实在是肤浅而又“同质化”的，对整个汽车产业的推动也是十分有限的。

你看看交通技术期刊或者直接去汉斯出版社的官网检索相关文献就可以哈，看看别人是怎么写的，你找找灵感
