汽车专业英语翻译综合

第一章汽车总论 1)Today’s average car contains more than 15,000 separate, individual parts that must work together. These parts can be grouped into four major categories: body, engine, chassis and electrical equipment 。P1 现在的车辆一般都由15000多个分散、独立且相互配合的零部件组成。这些零部件主要分为四类:车身、发动机、底盘和电气设备。 2)The engine acts as the power unit. The internal combustion engine is most common: this obtains its power by burning a liquid fuel inside the engine cylinder. There are two types of engine: gasoline (also called a spark-ignition engine) and diesel (also called a compression-ignition engine). Both engines are called heat engines; the burning fuel generates heat which causes the gas inside the cylinder to increase its pressure and supply power to rotate a shaft connected to the power train. P3 发动机作为动力设备,常见的类型是内燃机,其原理是通过发动机缸内的液体燃料燃烧而产生能量。发动机可分为两类:汽油机(点燃式)和柴油机(压燃式),都属于热力发动机。燃料燃烧产生热量使缸内气压上升,产生的能量驱动轴旋转,并传递给动力传动系。 第二章内燃机 1)Power train system: conveys the drive to the wheels 2)Steering system: controls the direction of movement 3)Suspension system: absorbs the road shocks 4)Braking system: slows down the vehicle P4 传动系把发动机输出的扭矩传递给驱动轮。传动系包括离合器(对应机械变速器)或液力变矩器(对应液力自动变速器)、变速器、驱动轴、主减速器、差速器和驱动桥。 5)Drum brakes have a drum attached to the wheel hub, and braking occurs by means of brake shoes expanding against the inside of the drum. With disc brakes, a disc attached to the wheel hub is clenched between two brake pads. P6 鼓式制动器的制动鼓和轮毂连接,制动蹄张开压紧制动鼓内侧从而产生制动。在盘式制动器上,连着轮毂的制动盘被紧紧夹在两个制动块之间。 1)Linking the piston by a connecting rod to a crankshaft causes the gas to rotate the shaft through half a turn.The power stroke"uses up"the gas,so means must be provided to expel the burnt gas and recharge the cylinder with a fresh petrol-air mixture:this control of gas movement is the duty of the valves;An inlet valve allows the mixture to enter at the right time and an exhaust valve lets out the burnt gas after the gas has done its job . P10 活塞通过连杆和曲轴连接,使得气体带动曲轴旋转半圈。作功冲程耗尽了所有的气体,这样就必须采取相应的措施排出废气并且向气缸内充入新的可燃混合气:气体的运动由气门来控制。进气门使可燃混合气在恰当的时刻进入气缸,排气门使燃烧后的废气排出气缸。 2)The spark-ignition engine is an internal-combustion engine with externally supplied in ignition,which converts the energy cntained in the fuel to kinetic energy.The cycle of operations is spread over four piston strokes. To complete the full cycle it takes two revolutions of the crankshaft. P11 火花点火式发动机是由外部提供点火的内燃机,从而将含在燃料内的能量转化成动能。发动机的一个工作循环分布在活塞的四个行程中,一个完整的工作循环曲轴需要转动两圈。 3)The oil pump in the lubricating system draws oil from the oil pan and sends it to all working parts in the engine. The oil drains off and runs down into the pan. Thus,there is constant circulation of oil between the pan and the working parts of the engine. P15

食品安全国内外文献综述

国内外文献综述 食品安全是一个与人类生存密切相关的问题,它涉及到资源配置与环境保护、需求的满足与社会福利的改善以及社会稳定等方面,也是农业持续发展的重要环节。不同时期由于食品安全所面临的主要问题不同,研究的侧重点也不相同。本章通过对食品安全相关文献的回顾与比较,以掌握对这一问题的研究脉络。 国外研究文献综述 食品安全问题的提出 食品安全是一个不断发展的概念。国外对食品安全问题的认识经历了一个由侧重食品数量安全(food Sedcurity)到侧重食品质量安全的转变过程。1974年,联合国粮农组织(FAO)等机构举行的世界粮食会议上,将食品安全定义为:所有人在任何情况下都能获得维持健康的生存所必需的足够食物。1983年,FAO前总干事爱德华·萨乌马将食品安全最终目标解释为确保 所有人在任何时候既能买得到又能买得起他们所需要的基本食品。这一概念主要强调了一国的食品供给数量能否满足人口的基本需要,并且更关注社会弱势人群(如穷人、妇女和儿童等)的食品可获得性,以避免和减少饥荒和营养不良现象的发生,因而与缓解和消除贫困问题之间存在着紧密联系。1984年,世界卫生组织(WHO)在题为《品安全在卫生和发展中的作用》的文件中,把“食品安全”与“食品卫生”作为同意语,定义为:“生产、加工、储存、分配和制作食品过程中确保食品安全可靠,有益于健康并且适合人消费的种种必要条件和措施”。1996年,WHO在《加强国家级食品安全性计划指南》中,对食品安全与食品卫生这两个概念进行了区别,其中食品安全被解释为“对食品按其原定用途进行制作和或食用时不会使消费者受害的一种担保”,食品卫生则指“为确保食品安全性和适合性在食物链的所有阶段必须采取的一切条件和措施”。 食品安全规制主体 食品安全规制的主体主要有规制机构、企业、用户(消费者)和非政府机构。针对消费者在食品安全规制中的作用,不同学者有不同观点: May Aung(2004)在研究中表明,所有国家必须考虑消费者利益,使消费者能够参加培训、决策以及国家食品安全系统的发展、调整和实施活动; AndrewFearne,JulieA.Caswell和Spence Henson(2007)的研究表明:根据各国食品安全形势、食品行业特征、消费者消费行为模式的不同,各国对食品行业的规制模式也有很大差异。Geoffrey podger(2005)的研究表明世界各国大致形成了两种食品安全规制机构设立模式,即以美国为代表的多部门共同负责的模式和以澳大利亚和新西兰为代表的由一个独

包装对食品发展的影响 消费者对某个产品的第一印象来说包装是至关重要的,包括沟通的可取性,可接受性,健康饮食形象等。食品能够提供广泛的产品和包装组合,传达自己加工的形象感知给消费者,例如新鲜包装/准备,冷藏,冷冻,超高温无菌,消毒(灭菌),烘干产品。 食物的最重要的质量属性之一,是它的味道,其影响人类的感官知觉,即味觉和嗅觉。味道可以很大程度作退化的处理和/或扩展存储。其他质量属性,也可能受到影响,包括颜色,质地和营养成分。食品质量不仅取决于原材料,添加剂,加工和包装的方法,而且其预期的货架寿命(保质期)过程中遇到的运输和储存条件的质量。越来越多的竞争当中,食品生产商,零售商和供应商;和质量审核供应商有着显著的提高食品质量以及急剧增加包装食品的选择。这些改进也得益于严格的冷藏链中的温度控制和越来越挑剔的消费者。 保质期的一个定义是:在规定的贮存温度条件下产品保持其质量和安全性的时间。在保质期内,产品的生产企业对该产品质量符合有关标准或明示担保的质量条件负责,销售者可以放心销售这些产品,消费者可以安全使用。 保质期不是识别食物等产品是否变质的唯一标准,可能由于存放方式,环境等变化物质的过早变质。所以食物等尽量在保质期未到期就及时食用。包装产品的质量和保质期的主题是在第3章中详细讨论。

包装为消费者提供有关产品的重要信息,在许多情况下,使用的包装和/或产品,包括事实信息如重量,体积,配料,制造商的细节,营养价值,烹饪和开放的指示,除了法律准则的最小尺寸的文字和数字,有定义的各类产品。消费者寻求更详细的产品信息,同时,许多标签已经成为多语种。标签的可读性会是视觉发现的一个问题,这很可能成为一个对越来越多的老年人口越来越重要的问题。 食物的选择和包装创新的一个主要驱动力是为了方便消费者的需求。这里有许多方便的现代包装所提供的属性,这些措施包括易于接入和开放,处置和处理,产品的知名度,再密封性能,微波加热性,延长保质期等。在英国和其他发达经济体显示出生率下降和快速增长的一个相对富裕的老人人口趋势,伴随着更加苛刻的年轻消费者,他们将要求和期望改进包装的功能,如方便包开启(百货配送研究所,IGD)。 对零售商而言存在有一个高的成本,供应和服务的货架体系。没有储备足够的产品品种或及时补充库存,特别是副食品,如鲜牛奶,可能导致客户不满和流失到竞争对手的商店,这正需要保证产品供应。现代化的配送和包装系统,允许消费者在购买食品时,他们希望在他们想任何时间地点都能享用。近几年消费者的选择已在急剧扩大。例如在英国,20世纪60年代和90年代之间在一般超市的产品线的数量从2000年左右上升到超过18000人(INCPEN)。 自20世纪70年代以来,食品卫生和安全问题已成为日益重要的关注和选择食物的驱动力。媒体所关注的一系列问题,如使用化学添

Fuel Supply System of Gasoline Engine(UNIT SEVEN) All the gasoline engines have substantially identical fuel systems and run on a mixture consisting of fuel vapor and air. The fuel system comprises the units designed to store, clear and deliver fuel, the units intended to clean air and a unit for preparing a mixture from fuel vapor and air. In a fuel system different components are used to supply fuel from the fuel tank into the engine cylinder. Some of the important components are fuel tank, fuel pump, fuel filter, carburetor, intake manifold and fuellines or tubes connecting the tank, pump and the carburetor. The fuel tank is a fuel container used for storing fuel. It is made of sheet metal. It is attached to the vehicle frame with metal traps and is located at the rear of the vehicle. They are mounted in a boot or boot-floor pan in case of front-engined cars and small commercial vehicles. In order to strengthen the tank as well as to prevent surging of fuel when the vehicle rounds a curve of suddenly stops, baffle plates are attached to the inside of the tank. A cap is used to close the filler opening of the tank. The fuel line is attached at or near the bottom of the tank with a filtering element placed at the connection. The other components of the fuel tank are the fuel gauge sending unit, a vent pipe, receiving unit. To prevent the dirt and water from entering the luggage compartment, a sealing strip is fitted between the fuel tank and boot floor pan. Moreover to limit the transmission of frame distortion to the tank giving rise to squeaking as the metal parts get rubbed together, rubber or felt pads are often fitted between the mountings and the tank. Provision is also made against drumming of the tank by these mountings. The tank may be placed at the side of the chassis frame for convenience in case of large commercial vehicles. The length of the connecting lines or tubes from the tank to the carburetor is also restricted by this at the same time. A porous filter is attached to the outlet lines. By drawing fuel from the tank through the filter, any water in the bottom of the tank as well as any dirt into the fuel gathers on the surface of the filter. To keep the fuel always under atmospheric pressure, the filter pipe or tank is vented. In order to prevent dirt in the fuel from entering the fuel pump or carburetor, fuel filters and screens are used in the fuel system. If the dirt is not removed from the fuel, the normal operation of these units will be prevented. The engine performance will also be reduced.
