The development of automobile

As the world energy crisis and the war and the energy consumption of oil -- and are full of energy in one day someday it will disappear without a trace. Oil is not inresources. So in oil consumption must be clean before finding a replacement. With the development of science and technology the progress of the society people invented the electric car. Electric cars will become the most ideal of transportation.

In the development of world each aspect is fruitful especially with the automobile electronic technology and computer and rapid development of the information age. The electronic control technology in the car on a wide range of applications the application of the electronic device cars and electronic technology not only to improve and enhance the quality and the traditional automobile electrical performance but also improve the automobile fuel economy performance reliability and emission spurification. Widely used in automobile electronic products not only reduces the cost and reduce the complexity of the maintenance. From the fuel injection engine ignition devices air control and emission control and fault diagnosis to the body auxiliary devices are generally used in electronic control technology auto development mainly electromechanical integration. Widely used in automotive electronic control ignition system mainly electronic control fuel injection system electronic control ignition system electronic control automatic transmission electronic control ABS/ASR control system electronic control suspension system electronic control power steering system vehicle dynamic control system the airbag systems active belt system electronic control system and the automatic air-conditioning and GPS navigation system etc. With the system response the use function of quick car high reliability guarantees of engine power and reduce fuel consumption and emission regulations meet standards.

The car is essential to modern traffic tools. And electric cars bring us infinite joy will give us the physical and mental relaxation. Take for example automatic transmission in road can not on the clutch can achieve automatic shift and engine flameout not so effective improve the driving convenience lighten the fatigue strength. Automatic transmission consists mainly of hydraulic torque converter gear transmission pump hydraulic control system electronic control system and oil cooling system etc. The electronic control of suspension is mainly used to cushion the impact of the body and the road to reduce vibration that car getting smooth-going and stability. When the vehicle in the car when the road uneven road can according to automatically adjust the height. When the car ratio of height low set to gas or oil cylinder filling or oil. If is opposite gas or diarrhea. To ensure and improve the level of driving cars driving stability. Variable force power steering system can significantly change the driver for the work efficiency and the state so widely used in electric cars. VDC to vehicle performance has important function it can according to the need of active braking to change the wheels of the car car motions of state and optimum control performance and increased automobile adhesion controlling and stability. Besides these appear beyond 4WS 4WD electric cars can greatly improve the performance of the value and ascending simultaneously. ABS braking distance is reduced and can keep turning skills effectively improve the stability of the directions simultaneously reduce tyre wear. The airbag appear in large programs protected the driver and passengers safety and greatly reduce automobile in collision of drivers and passengers in the buffer to protect the safety of life.

ABS GPS and various new 4WD 4WS electronic products and the modern era excellent performance auto tacit understanding is tie-in bring us unparalleled precision driving comfort and safety of driving.

汽车的发展

随着世界能源危机的持续,以及战争和能源-----石油的消耗及汽车饱有量的增加,能源在一天一天下降,终有一天它会消失的无影无踪。石油不是在生资源。所以必须在石油耗净之前找到一种代替品。随着科技的发展社会的进步,有人发明了电动汽车。电动汽车将成为人们最为理想的交通工具。世界在各各方面的发展都取得丰硕成果,尤其是随着汽车电子技术和计算机以及发展迅速的信息时代。电子控制技术在汽车上得到了广泛应用,汽车上应用的电子装置越来越丰富,电子技术不仅用来改善和提高传统汽车电器的质量和性能,而且还提高了汽车的动力性、燃油经济性、可靠性以及废气排放的净化性。汽车上广泛使用电子产品不仅降低了成本,并且减少维护的复杂性。从发动机的燃油喷射点火装置、进气控制、废气排放控制、故障自诊断到车身辅助装置都普遍采用了电子控制技术,可以说今后汽车发展主要以机电一体化。汽车上广泛采用的电子控制点火系统主要有电子控制燃油喷射系统、电子控制点火系统、电子控制自动变速器、电子控制防滑(ABS/ASR)控制系统、电子控制悬架系统、电子控制动力转向系统、车辆动力学控制系统、安全气囊系统、主动安全带系统、电子控制自动空调系统、导航系统还有GPS 等。有了这些系统汽车响应敏捷,使用功能强,可靠性高,既保证发动机动力又降低燃油的消耗,而且又满足排放法规的标准。汽车是现代人必不可少的交通工具。而电动汽车给我们带来无限乐趣外还能给我们劳累一天的身心得以放松。就拿自动变速器来说吧,汽车在行驶时,可以不踩离合器踏板,就可以实现自动换档而发动机不会熄火,这样有效的提高驾驶方便性减轻驾驶员的疲劳强度。自动变速器主要由液力变矩器、齿轮变速器、油泵、液压控制系统、电子控制系统、油冷却系统等组成。电子控制的悬架主要是用来缓冲路面对车身的冲击力以及减少振动保证汽车平顺性和操纵稳定性。当汽车行驶在不平坦的道路时汽车能能根据底盘和路面高度自动调整。当车高比设置的高度低时,就向气室或油缸充气或充油。如果是相反,就放气或泻油。从而保证汽车的水平行驶,提高行驶稳定性。可变力动力转向系统因能显著改变驾驶员的工作效率和状态,所以在电动汽车上广泛使用。VDC 对汽车性能有着至关重要的作用它能根据需要主动对车轮进行制动来改变汽车的运动状态,使汽车达到最佳的行驶状态和操纵性能,并增加了汽车的附着性,控制性和稳定性。除了这些之外4WS、4WD 的出现大大提高了电动汽车的价值

与性能同步提升。ABS 具有减少制动距离并能保持转向操作能力有效提高行驶方向的稳定性同时减少轮胎的磨损。安全气囊的出现在很大程序上保护了驾驶员和乘客的安全,大大降低汽车在碰撞时对驾驶员和乘客的缓冲,以过到保护生命安全的目的。智能电子技术在汽车上得以推广使得汽车在安全行驶和其它功能更上一层楼。通过各种传感器实现自动驾驶。除些之外智能汽车装备有多种传感器能充分感知交通设施及环境的信息并能随时判断车辆及驾驶员是否处于危险之中,具备自主寻路、导航、避撞、不停车收费等功能。有效提高运输过程中的安全,减少驾驶员的操纵疲劳度,提高乘客的舒适度。当然蓄电池是电动汽车的关键,电动汽车用的蓄电池主要有:铅酸蓄电池、镍镉蓄电池、钠硫蓄电池、钠硫蓄电池、锂电池、锌―空气电池、飞轮电池、燃料电池和太阳能电池等。在诸多种电池中,燃料电池是迄今为止最有希望解决汽车能源短缺问题的动力源。燃料电池具有高效无污染的特性,不同于其他蓄电池,其不需要充电,只要外部不断地供给燃料,就能连续稳定地发电。燃料电池汽车FCEV具有可与内燃机汽车媲美的动力性能,在排放、燃油经济性方面明显优于内燃机车辆。随着计算机和电子产品不断开级换代,电动汽车技术也在日趋成熟与完善,使得驾驶更安全、方便、灵活、舒适。现在,电动汽车离普通消费者的距离还很遥远,只有少数人在赶赶时髦而已。电动汽车真正能够与传统的燃油汽车相竞争,今后汽车市场终会被电动汽车和智能汽车所取代。这只是时间性的问题这一天终究会来到的。ABS、GPS、4WS、4WD 以及各种新时代的电子产品与现代高性能汽车默契组合、绝妙搭配,带给我们无与伦比的精准驾驶舒适性和行驶安全性。

01-文献综述范文-翻译-当前零翻译研究问题与对策

外国语学院2018届毕业论文文献综述(示范) 一、研究背景 近来多篇论文中出现零翻译的提法(杜争鸣,2000;邱懋如,2001;刘明东,2002;袁斌业,2002a,2002b,2002c,2002d;石琳,2003;余清萍,2003;余清萍,秦傲松,2004;肖耀田,2004),但国内学者所编三本译学词典(林煌天,1997;孙迎春,1999;方梦之,2004)均未出现零翻译这一词条,国外三本词典/术语著作(Shuttleworth & Cowie,1997;Baker,1998;Delisle,2004)亦未收入这一条目,只有国内孙迎春(2001)编著的《汉英双向翻译学语林》收进了“零翻译(音译、形译之一种)zero translation”(58页)及“zero translation零翻译(音译、形译之一种)”(268页)两个条目,同时又有贾影(2002)反对零翻译提法,并认为承认不可译有“积极作用”。但零翻译现象确实存在,如DIY(自己动手),IQ(智商),EQ(情商),这些零翻译词汇经常在汉语中出现。英语中也有类似情况,如美国《时代》周刊中报道中国特色事物时经常使用拼音,如aizi(矮子),pizi(痞子),shiganjia(实干家),yuan(缘)(王祥兵,2002),shuangying(双赢),guanxi(关系)(顾静,2005)。 这些研究成果揭示了零翻译现象的存在,引进了零翻译的概念,促进了翻译理论概念的扩大,但是从发表的论文及孙迎春(2001)的这两个条目来看,各自运用的名称虽同(也有不同,如杜争鸣称为不译),但概念的内涵及外延均有出入,因此有必要探讨当前零翻译研究的问题并提出相应研究对策。 二、研究现状及不足 1. 定义不统一、模糊不清 传统翻译理论多把零翻译归结为“音译法”、“移译法”,只看到技巧层面的意义,如秦建栋(1999)讨论“英汉词汇空缺现象刍议”列举“音译法”、“移译法”,袁斌业(2001)论及“英语本族人音译汉语词汇的语用分析”,虽然看到“音译在我国只能用来翻译名词,而在国外则可以用来翻译包括名词在内的各种词语”,但未能从中提炼出零翻译的概念,实际上这里已包含有零翻译与音译的某些区别。 国内最早使用zero translation这一术语的是杜争鸣(2000),但他称之为“不译”,并分析了直译、意译与不译三种翻译策略。他不停留于策略本身,从跨文化交际的视角分析了三种策略的社会语言学与跨文化交际涵义,并看到了不译的三层文化含义。不译背后体现译者对于翻译目的的认识,“而翻译的目的必然直接或间接地反映反映译者本人对翻译的文化含义的意识与潜意识,反映他翻译时所采取的文化姿态与立场。”即翻译观的问题。但从术语的精确性来说

摘要 将稳定控制系统应用于差动制动内/外轮胎是现在对客车车辆的标准(电子稳定系统ESP、直接偏航力矩控制DYC)。这些系统假设将两个偏航率(通常是衡量板)和侧滑角作为控制变量。不幸的是后者的具体数值只有通过非常昂贵却不适合用于普通车辆的设备才可以实现直接被测量,因此只能估计其数值。几个州的观察家最终将适应参数的参考车辆模型作为开发的目的。然而侧滑角的估计还是一个悬而未决的问题。为了避免有关参考模型参数识别/适应的问题,本文提出了分层神经网络方法估算侧滑角。横向加速度、偏航角速率、速度和引导角,都可以作为普通传感器的输入值。人脑中的神经网络的设计和定义的策略构成训练集通过数值模拟与七分布式光纤传感器的车辆模型都已经获得了。在各种路面上神经网络性能和稳定已经通过处理实验数据获得和相应的车辆和提到几个处理演习(一步引导、电源、双车道变化等)得以证实。结果通常显示估计和测量的侧滑角之间有良好的一致性。 1 介绍 稳定控制系统可以防止车辆的旋转和漂移。实际上,在轮胎和道路之间的物理极限的附着力下驾驶汽车是一个极其困难的任务。通常大部分司机不能处理这种情况和失去控制的车辆。最近,为了提高车辆安全,稳定控制系统(ESP[1,2]; DYC[3,4])介绍了通过将差动制动/驱动扭矩应用到内/外轮胎来试图控制偏航力矩的方法。 横摆力矩控制系统(DYC)是基于偏航角速率反馈进行控制的。在这种情况下,控制系统使车辆处于由司机转向输入和车辆速度控制的期望的偏航率[3,4]。然而为了确保稳定,防止特别是在低摩擦路面上的车辆侧滑角变得太大是必要的[1,2]。事实上由于非线性回旋力和轮胎滑移角之间的关系,转向角的变化几乎不改变偏航力矩。因此两个偏航率和侧滑角的实现需要一个有效的稳定控制系统[1,2]。不幸的是,能直接测量的侧滑角只能用特殊设备(光学传感器或GPS惯性传感器的组合),现在这种设备非常昂贵,不适合在普通汽车上实现。因此, 必须在实时测量的基础上进行侧滑角估计,具体是测量横向/纵向加速度、角速度、引导角度和车轮角速度来估计车辆速度。 在主要是基于状态观测器/卡尔曼滤波器(5、6)的文学资料里, 提出了几个侧滑角估计策略。因为国家观察员都基于一个参考车辆模型,他们只有准确已知模型参数的情况下,才可以提供一个令人满意的估计。根据这种观点,轮胎特性尤其关键取决于附着条件、温度、磨损等特点。 轮胎转弯刚度的提出就是为了克服这些困难,适应观察员能够提供一个同步估计的侧滑角和附着条件[7,8]。这种方法的弊端是一个更复杂的布局的估计量导致需要很高的计算工作量。 另一种方法可由代表神经网络由于其承受能力模型非线性系统,这样不需要一个参

The Competitive Dynamics in the Automotive Aftermarket: Branded Products and Private Label Products THE BUSINESS CASE Throughout the automotive aftermarket industry,senior executives are facing the reality of private brands. Similar dynamics exist outside of the automotive aftermarket and are intensifying in other sectors, such as traditional consumer goods. Also known as ―private label‖ and referred to across many consumer-oriented industries as ―store brands,‖ ―control brands‖ or ―own brands,‖ their risin g prominence has led top executives to ask: ? What issues and risks do U.S.-branded manufacturers face with respect to private brands? ? How are market forces different today than in years past? How will this landscape evolve? ? How can I better understand my operational blind spots in an increasingly competitive landscape? ? What can my management team focus on to protect and grow my brands? Where do we start? ?What are the similarities and differences between the private brand trends in the automotive aftermarket and the consumer products sector? ? What can be learned by automotive aftermarket executives from the private brand experiences in other sectors? Although answers to these questions are not simple and some market dynamics are not yet fully clear, the availability of private brands and other competitive trends are growing in the automotive aftermarket community, just as they are in many consumer product segments. One out of every three consumer products sold by one of the nation’s largest retailers is now private brand – up from one out of every five just a few years ago. With U.S. private brand sales in the grocery market surpassing well over $80 billion, for example, private brands can no longer be ignored by consumer product manufacturers. The U.S. market share of private brands in food, drug and mass merchant channels is more than 20 percent, according to industry data research firms. More than 80 percent of consumers shopping in big box, warehouse clubs and superstores frequently buy store brands and, depending on the specific product category, multiple store brands at a time. Retailers are focusing more resources on private branding to enhance margins, increase shelf velocity and expand store

图像科学综述 外文翻译 外文文献 英文文献

附录 图像科学综述 近几年来,图像处理与识别技术得到了迅速的发展,现在人们己充分认识到图像处理和识别技术是认识世界、改造世界的重要手段。目前它己应用于许多领域,成为2l世纪信息时代的一门重要的高新科学技术。 1.图像处理与识别技术概述 图像就是用各种观测系统以不同形式和手段观测客观世界而获得的,可以直接或间接作用于人眼而产生视知觉的实体。科学研究和统计表明,人类从外界获得的信息约有75%来自于视觉系统,也就是说,人类的大部分信息都是从图像中获得的。 图像处理是人类视觉延伸的重要手段,可以便人们看到任意波长上所测得的图像。例如,借助伽马相机、x光机,人们可以看到红外和超声图像:借助CT可看到物体内部的断层图像;借助相应工具可看到立体图像和剖视图像。1964年,美国在太空探索中拍回了大量月球照片,但是由于种种环境因素的影响,这些照片是非常不清晰的,为此,美国喷射推进实验室(JPL)使用计算机对图像进行处理,使照片中的重要信息得以清晰再现。这是这门技术发展的重要里程碑。此后,图像处理技术在空间研究方面得到广泛的应用。 总体来说,图像处理技术的发展大致经历了初创期、发展期、普及期和实用化期4个阶段。初创期开始于20世纪60年代,当时的图像采用像素型光栅进行扫描显示,大多采用巾、大型机对其进行处理。在这一时期,由于图像存储成本高,处理设备造价高,因而其应用面很窄。20世纪70年代进入了发展期,开始大量采用中、小型机进行处理,图像处理也逐渐改用光栅扫描显示方式,特别是出现了CT和卫星遥感图像,对图像处理技术的发展起到了很好的促进作用。到了20世纪80年代,图像处理技术进入普及期,此时购微机已经能够担当起图形图像处理的任务。VLSL的出现更使得处理速度大大提高,其造价也进一步降低,极大地促进了图形图像系统的普及和应用。20世纪90年代是图像技术的实用化时期,图像处理的信息量巨大,对处理速度的要求极高。 21世纪的图像技术要向高质量化方面发展,主要体现在以下几点:①高分辨率、高速度,图像处理技术发展的最终目标是要实现图像的实时处理,这在移动

汽车保险 汽车保险是在事故后保证自己的财产安全合同。尽管联邦法律没有强制要求,但是在大多数州(新罕布什和威斯康星州除外)都要求必须购买汽车保险;在各个州都有最低的保险要求。在鼻腔只购买汽车保险的两个州,如果没有足够的证据表明车主财力满足财务责任法的要求,那么他就必须买一份汽车保险。就算没有法律规定,买一份合适的汽车保险对司机避免惹上官和承担过多维修费用来说都是非常实用的。 依据美国保险咨询中心的资料显示,一份基本的保险单应由6个险种组成。这其中有些是有州法律规定,有些是可以选择的,具体如下: 1.身体伤害责任险 2.财产损失责任险 3.医疗险或个人伤害保护险 4.车辆碰撞险 5.综合损失险 6.无保险驾驶人或保额不足驾驶人险 责任保险 责任险的投保险额一般用三个数字表示。不如,你的保险经纪人说你的保险单责任限额是20/40/10,这就代表每个人的人身伤害责任险赔偿限额是2万美元,每起事故的热身上海责任险赔偿限额是4万美元,每起事故的财产损失责任险的赔偿限额是1万美元。 人身伤害和财产损失责任险是大多数汽车保险单的基础。要求汽车保险的每个州都强令必须投保财产损失责任险,佛罗里达是唯一要求汽车保险但不要求投保人身伤害责任险的州。如果由于你的过错造成了事故,你的责任险会承担人身伤害、财产损失和法律规定的其他费用。人身伤害责任险将赔偿医疗费和误工工资;财产损失责任险将支付车辆的维修及零件更换费用。财产损失责任险通常承担对其他车辆的维修费用,但是也可以对你的车撞坏的灯杆、护栏、建筑物等其他物品的损坏进行赔偿。另一方当事人也可以决定起诉你赔偿精神损失。

汽车变速器设计外文翻译

汽车变速器设计 ----------外文翻译 我们知道,汽车发动机在一定的转速下能够达到最好的状态,此时发出的功率比较大,燃油经济性也比较好。因此,我们希望发动机总是在最好的状态下工作。但是,汽车在使用的时候需要有不同的速度,这样就产生了矛盾。这个矛盾要通过变速器来解决。 汽车变速器的作用用一句话概括,就叫做变速变扭,即增速减扭或减速增扭。为什么减速可以增扭,而增速又要减扭呢?设发动机输出的功率不变,功率可以表示为 N = w T,其中w是转动的角速度,T是扭距。当N固定的时候,w与T是成反比的。所以增速必减扭,减速必增扭。汽车变速器齿轮传动就根据变速变扭的原理,分成各个档位对应不同的传动比,以适应不同的运行状况。 一般的手动变速器内设置输入轴、中间轴和输出轴,又称三轴式,另外还有倒档轴。三轴式是变速器的主体结构,输入轴的转速也就是发动机的转速,输出轴转速则是中间轴与输出轴之间不同齿轮啮合所产生的转速。不同的齿轮啮合就有不同的传动比,也就有了不同的转速。例如郑州日产ZN6481W2G型SUV车手动变速器,它的传动比分别是:1档3.704:1;2档2.202:1;3档1.414:1;4档1:1;5档(超速档)0.802:1。 当汽车启动司机选择1档时,拨叉将1/2档同步器向后接合1档齿轮并将它锁定输出轴上,动力经输入轴、中间轴和输出轴上的1档齿轮,1档齿轮带动输出轴,输出轴将动力传递到传动轴上(红色箭头)。典型1档变速齿轮传动比是3:1,也就是说输入轴转3圈,输出轴转1圈。 当汽车增速司机选择2档时,拨叉将1/2档同步器与1档分离后接合2档齿轮并锁定输出轴上,动力传递路线相似,所不同的是输出轴上的1档齿轮换成2档齿轮带动输出轴。典型2档变速齿轮传动比是2.2:1,输入轴转2.2圈,输出轴转1圈,比1档转速增加,扭矩降低。
