B. 关于对电动汽车看法的150字英语作文
There is now more of said electric car refers to a pure electric car, which is a single energy storage batteries as a power source for vehicles. It uses batteries as energy storage power source to provide power through the battery to the motor, drive motor running to drive the car forward. From the appearance point of view, the electric car and the daily car and did not see any difference, the main difference between the power source and the drive system. That pure electric vehicle motor of a traditional car engine, battery equivalent to the original tank. Electric car from the chassis, body, battery, motor, controller and battery auxiliary facilities of six parts. Since the motor has good traction characteristics, and therefore does not require a battery vehicle driveline clutch and transmission. Speed is controlled by the controller changes the speed of the motor speed control system can be achieved by conventional cars because of the relatively small impact on the environment, the outlook is widely optimistic, but
The current technology is not yet mature.
目前人们所说的电动汽车多是指纯电动汽车,即是一种采用单一蓄电池作为储能动力源的汽车。它利用蓄电池作为储能动力源,通过电池向电机提供电能,驱动电动机运转,从而推动汽车前进。从外形上看,电动汽车与日常见到的汽车并没有什么区别,区别主要在于动力源及其驱动系统。即纯电动汽车的电动机相当于传统汽车的发动机,蓄电池相当于原来的油箱。 电动汽车由底盘、车身、蓄电池组、电动机、控制器和辅助设施蓄电池六部分组成。由于电动机具有良好的牵引特性,因此蓄电池汽车的传动系统不需要离合器和变速器。车速控制由控制器通过调速系统改变电动机的转速即可实现由于对环境影响相对传统汽车较小,其前景被广泛看好,但
当前技术尚不成熟。
C. 求一篇有关电动平车的英文文章(3000字左右,最好带汉语翻译)
电动平车,是一种电动有轨厂内运输车辆。又称台车、过跨车。它具有结构简单、使用方便、容易维护、承载能力大、污染少等优点。广泛用于机器制造和冶金工厂,作为车间内部配合吊车运输重物过跨之用。KP 系列电动平车高度低,台面加强,改型容易,维修方便。
KPJ系列是卷筒供电电动平车,以电缆卷筒交流380V供电。电缆卷筒为磁滞耦合式,确保电缆受力均匀不易拉坏。交流380V给平车上YZ起重冶金用电机提供电力,电机拖动平车运行。平车运行时电缆卷筒自动将电缆卷起或放出,受卷线筒供电长度影响,一般最大运行距离小于200m。
KPD系列是36V单相(三相)低压轨道供电电动平车,以轨道滑触线供电。地面降压变压器控制柜将单相(三相)交流380V降压至单相(三相)36V,经轨道滑触线馈送给平车,再经车载升压变压器升压为单相(三相)交流380V。给平车用单相电容电机提供电力(三相时为YZ起重冶金用电机)。由于不用电缆,故安全可靠、不怕烫,不怕砸,不妨碍交叉运输,易实现遥控和自动化,给厂区运输布置以很大方便。但其轨道施工要求较高,须保证轨道绝缘,超过一定的运行距离时轨道应加铜排补偿线。运行距离较长时还必须增加降压变压器个数。
由于KPD 平车起动时流经轨道的起动电流非常大(达1000A),此时轨道末端有很大的电压降,造成单相电容电机起动困难,故单相KPD平车最大载重吨位为50吨,载重50吨以上时采用三相36V低压轨道供电,YZ起重冶金用电机。
产品KPDZ既继承了KPD平车的优点又避免了原型号起动困难,运行距离短的缺点。KPDZ平车以车载整流装置将轨道上的单相(或三相)交流36V整流成直流36V,拖动直流牵引电机使平车运行,直流电机与交流电机相比有不易烧损,起动力矩大,过载能力强的优点。即使由于轨道绝缘老化等原因,在欠压的工况下仍能可靠工作。

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 for. 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 in. Carbon fibre is an expensive alternative to making things in steel or aluminium, but besides being extremely strong it is also very light. It is found in high-performance parts, like aircraft wings, bits of supercars and the frames of pricey mountain bikes. But if work by Germany’s BMW proves successful, it could also become the material of choice to mass-proce electric cars.
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 2013. It will be one of the first designed from scratch to use an electric motor rather than being converted from an existing model. Recing the weight of this four-seater car, known as the Megacity concept, will be crucial to improving its performance and range. So BMW is planning to use no steel at all. The Megacity will be built as two moles: an aluminium chassis will contain the electric drive-system and battery, and a body made almost entirely of carbon fibre will be fitted onto it.
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 steel. The fibres are extremely tear-resistant. When woven into a lattice structure and impregnated with resin they can proce a part that is stronger than steel. 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 autoclaves. For carmakers, used to stamping out steel body-parts in a few seconds, this has ruled out carbon fibre for high-volume proction. BMW, however, aims to change that.
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 proction line starts with a so-called precursor: a fibre spun from a polymer. This is carbonised by heating it in multiple stages to leave indivial carbon fibres just seven microns (0.007 millimetres) thick. Around 50,000 of these fibres are bundled together into a yarn which is then made into a fabric. This can be cut and handled like a textile. 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 suit.
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(0.007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 proce contours in the fabric. Resin is then injected into the molds to bond the fibres together. How the resin flows through the fibres is crucial; it has to be done quickly and leave no area untreated before it starts to cure. A release agent in the resin migrates to the surface to prevent the component sticking in the mold. The whole process, which can be handled by robots, is completed in minutes.
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 car. Besides their lightness, BMW’s experimental vehicles have exceeded expectations in crash tests, says the company. During front- and rear-impact-tests the aluminium chassis crumples to absorb energy, but leaves the rigid carbon-fibre passenger compartment intact. Even extreme side-impacts protected the crash mmies 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 ones.
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 scrapped. Steel and aluminium is easy to recycle, but carbon fibre is tricky. Carmakers are working with aerospace firms on ways to do it. BMW has pioneered a process to reuse offcuts by breaking them up with heat to turn them back into raw material. This can be used to make composites with about half the strength of new carbon fibre.
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 corrode. 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 model.
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。

Advantages and Disadvantages of EVs
The most obvious advantage of electric car batteries is that they don't proce the pollution associated with internal combustion engines. However, they still have environmental costs. The electricity used to recharge EV batteries has to come from somewhere, and right now, most electricity is generated by burning fossil fuels. Of course, this proces pollution. But how does the pollution proced by burning fossil fuels to recharge electric car batteries compare to the pollution proced by internal combustion engines? According to the Electric Vehicle Association of Canada, or EVAC, even EVs recharged from coal-powered electric generators cut carbon emission roughly in half. EVs recharged from cleaner forms of electrical power generation, such as hydropower and nuclear plants, can rece carbon emissions to less than one percent of those currently proced by internal combustion engines. So, even in the worst case scenario, cars operated by EV batteries are cleaner than gas-powered cars.
Another important advantage of battery-powered motors over gas-powered engines is the lower cost of the fuel -- that is, electricity for EVs and gas for the internal combustion engines. The United States Department of Energy has calculated that a typical EV can run for 43 miles on a dollar's worth of electricity. Only a substantial drop in the cost of gasoline could give gas-powered cars anywhere near such a low cost per mile.
Yet another advantage of these rechargeable batteries is that they recycle well. Almost 100 percent of these batteries can be recycled, which keeps old batteries from becoming a disposal problem.
The major disadvantage of battery-powered cars, as we mentioned in the last section, is the time required to recharge the batteries. With lithium-ion battery technology, a fully charged EV can travel a distance comparable to an internal combustion engine vehicle with a full tank of gas, but it still needs to be placed on a recharger at the end of that time. At present, this means a drained EV will be out of service for several hours before it's fully recharged. Of course, this is a serious disadvantage. In the future, faster recharging technology may become available, but in the near term, electric cars won't be the vehicles of choice for long trips. Even so, most driving is done relatively close to home and for this reason, battery power will serve as well as gasoline power. A possible solution to the recharging situation may be battery-replacement stations, where instead of recharging your EV you can simply swap your drained battery for a fully charged one. This system would allow batteries to be recharged outside of vehicles and would greatly rece the amount of time required to get an EV up and running again after its battery is fully discharged.
Another disadvantage of electric car batteries is their weight. Because they need to do more than traditional car batteries, electric car batteries need to be linked together into arrays, or battery packs, to provide additional power. These collections of batteries are heavy. The lithium-ion battery pack in a Tesla Roadster weighs about 1,000 pounds (453.6 kg). That's a lot of weight to carry and it can greatly rece the car's range. However, the designers of the Roadster have offset this battery weight with a light frame and body panels. The entire car only weighs 2,690 pounds (1220.2 kg) -- not terribly heavy when you consider that more than a third of that weight is battery.
Given the importance of the battery to an electric car, you might wonder what will happen as that battery grows older. How long will it be able to power the car? And when it finally dies, can it be replaced or is it simply more economical to buy a new car? Read on to find out.
