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
企业物流外包外文翻译文献 (文档含英文原文和中文翻译) 物流外包——确保一个组织竞争优势的一种手段 摘要 物流方式表明将交付供应链中的独立单位整合成一个统一的系统的目标，完成结果所需的时间和资源的损失降到最小的材料和信息流动的直接管理。 一个最新方法的实施为公司的物流管理提供更多的成效，这个方法就是外包。物流外包带来诸多好处，如：减少库存、减少订单的交货时间、提高运输质
量、扩大生产的灵活性、降低生产成本和加速资金周转等。这保证了较低的生产成本和更好的质量交付，这是一个决定性的竞争优势。物流外包的应用有利于资源的合理配置，这是公司拥有的独特的竞争优势。 因此，物流外包将作为一种手段应用于公司的物流运输中，以确保一个组织的竞争优势。 关键词：外包，物流，供应商 1.简介 竞争优势，与不断增长的全球化和创新，开始逐渐失去其创意和新的竞争优势，在前端的灵活性，订单到交货时间减少，可靠的高质量的交付，和选择的机会。在竞争领域，厂家的能力加入其生产过程和系统的规划与个人消费者的喜好，将是一个的决定性的因素。只有通过建立灵活的生产管理系统，与个别客户订单问题的解决方案才是可能的。企业为什么要搞物流外包?它的紧迫性在哪里?物流外包与传统意义上的外委、外协有何本质区别?我们的企业离物流外包还远吗?这不仅是理论界要回答的问题，更是企业界应认真思考的问题。谈到物流外包必定涉及供应链和第三方的发展，涉及到现代物流的发展方向，更涉及企业的核心竞争力。理论界对这一点的认识显得有些浮躁，而企业对此的认识比较滞后。目前大多数企业守候在自营物流那片天地，真正搞物流外包的不到20%，并且不规范、不系统。尽管现在物流炒得很热，但企业对物流外包重要性的认识依然很浅。调查表明，湖南有82%的企业对现代物流的认识模糊，大多把货物运输或货代等同于现代物流;有54%的企业至今未有发展物流的计划或设想，更没有把重构内部供应链和发展物流外包提上议事日程，看来还需要更多的示范、引导，更多的宣传、培训和更多的市场培育。 首先，它需要的新的或最新的概念，如CFM（以客户为中心的制造），SCM（供应链管理），基于相同的概念作为企业资源规划（ERP），客户关系管理技术，生产管理的实施（客户关系管理）等，也将要求供应处理，物流中介机构的互动为基础的生产和有效的分配同步。 其次，它在微观和宏观层面上是一个必要的优化运输系统。复杂的运输基础设施的发展是基于标准化的商品，货物，运输方式，装卸货物，交货速度，拓宽道路和铁路网络，完善的售后服务维修。 第三，信息交流起着越来越重要的作用。工业企业在信息领域的互动，使信息可以以正确的形式被查阅，在合适的时间，通过正确的当局和真实类型，防止
附录 附录A Braking system function is to make the car driving in accordance with the requirements of the pilot required even slow down park; They offend car has in various road conditions (including in the slope stability) in car; Make the downhill cars speed to be stable. For car up the role of brake is only in the car and role with the direction of the car driving direction opposite forces, and the size of these forces are random, do not control, so cars must be installed on a series of special equipment to achieve the function. Automobile brake system is to point to to ensure that the car in technology, improve the safe driving car average speed, etc., and the admiration installed in the car brake special brake institutions. In general automobile brake system including crane brake system and parking brake two sets of independent device. One crane brake device is a driver with feet to manipulate, and it said the foot brake. Parking brake device is a pilot with the hand, so it says of the manipulation of the hand brake. The function of the crane brake system is to make the car slow down or running in the shortest distance parking within. And parking brake function is to make had stopped the car on the road all keep still. But, sometimes, in an emergency, two braking device can be used at the same time and increase the effect of auto brake. Some special purpose of cars and often in the mountains cars, long and frequently brake will lead to crane brake system overheating, so in these cars often add all sorts of different types of auxiliary braking equipment, so as to speed up the hill stability. According to the braking energy situation, brake system can also be divided into human brake system, power brake system, and servo brake system, three. Human brake system to the driver's physical strength as braking energy; Power brake system engine power to the transformation of the air pressure or hydraulic braking energy as; And servo brake system is the most human and engine power as a brake energy. In addition, according to the braking energy transfer mode, brake system and can be divided into mechanical and hydraulic, pneumatic type and assolenoid style wait until a few kinds.
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.

设施规划 引言 设施规划在过去的十年间已经被赋予了全新的意义。在过去，设施规划一般被认为是一门科学。而在当今竞争激烈的全球市场，设施规划成为了一种策略。政府、教育机构和企业已经不再单独相互竞争，现在这些实体或企业将彼此联合为合作企业、组织协会，并最终合成为供应链，将客户纳入到整个供应链过程以保持竞争力。 这些年来设施规划问题一直是一个热门话题。尽管它已拥有很悠久的历史，但在目前的出版物、会议以及研究中，设施规划仍是最受欢迎的科目之一。设施规划的处理已经从清单式或者菜单式的方法发展到了高度复杂的数学建模。在本文中，我们使用了一个实用的设施规划方法，其利用了实证以及同时包含传统和现代概念的分析方法。值得提及的是，在本文中拥有很广泛的设施规划应用示例。例如，这本书的内容可以适用于一个新医院,一个装配部门,一个已有的仓库,或者一个机场的行李部的规划。无论问题是发生在医院、生产工厂、配送中心、机场、零售商店、学校、银行、还是办公室或者这些设施的任何部分；无论是在一个发达国家的现代化设施还是在一个发展中国家的过时设施中，本文给出的材料在进行规划时都非常有用。重要的是要认识到现代设施规划中将设施当作是一个动态的实体，一个成功的设施规划方案的关键因素是其适应性以及适合全新应用的能力。 设施规划的定义 当今的设施规划必须能够帮助组织实现供应链的优越性。实现供应链的优越性是一个有六个步骤、或者说六个等级的过程。一如既往，这些步骤与优越性、可见性、协同性、综合性、敏捷性等联系在一起。 当一家公司最大化供应链的各个功能（采购-制造-运输-储存-销售），个体部门（如金融、市场营销、销售、采购、信息技术、研发、生产、分配和人力资源等部门）的目标就是要成为公司最好的部门。组织的有效性不是重点，每个组
Automobile Brake System The braking system is the most important system in cars. If the brakes fail, the result can be disastrous. Brakes are actually energy conversion devices, which convert the kinetic energy (momentum) of the vehicle into thermal energy (heat).When stepping on the brakes, the driver commands a stopping force ten times as powerful as the force that puts the car in motion. The braking system can exert thousands of pounds of pressure on each of the four brakes. Two complete independent braking systems are used on the car. They are the service brake and the parking brake. The service brake acts to slow, stop, or hold the vehicle during normal driving. They are foot-operated by the driver depressing and releasing the brake pedal. The primary purpose of the parking brake is to hold the vehicle stationary while it is unattended. The parking brake is mechanically operated by when a separate parking brake foot pedal or hand lever is set. The brake system is composed of the following basic c omponents: the “master cylinder” which is located under the hood, and is directly connected to the brake pedal, converts driver foot’s mechanical pressure into hydraulic pressure. Steel “brake lines” and flexible “brake hoses” connect the master cylinder to the cylinders” located at each wheel. Brake fluid, specially designed to work in extreme conditions, fills the system. “Shoes” and “pads” are pushed by cylinders to contact the “drums” and “rotors” thus causing drag, which (hopefully) slows the car. The typical brake system consists of disk brakes in front and either disk or drum brakes in the rear connected by a system of tubes and hoses that link the brake at each wheel to the master cylinder (Figure).

汽车保险中英文对照外文翻译文献(文档含英文原文和中文翻译)
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。
第三方物流问题战略外文翻译文献 (文档含英文原文和中文翻译) 我国第三方物流中存在的问题、原因及战略选择 【摘要】我国物流业发展刚刚起步，第三方物流的理论和实践等方面都比较薄弱。本文指出我国第三方物流存在的问题在于国内外第三方物流企业差距、物流效率不高、缺乏系统性管理、物流平台构筑滞后、物流管理观念落后等。分析了产生上述问题的原因，并提出了精益物流、中小型第三方物流企业价值链联盟、大型第三方物流企业虚拟化战等三种可供选择的第三方物流企业发展战略。【关键词】第三方物流；精益物流战略；价值链联盟；虚拟化战略 1引言 长期以来，我国国内企业对采购、运输、仓储、代理、包装、加工、配送等
环节控制能力不强，在“采购黑洞”、“物流陷井”中造成的损失浪费难以计算。因此，对第三方物流的研究，对于促进我国经济整体效益的提高有着非常重要的理论和实践意义。本文试图对我国策三方物流存在的问题及原因进行分析探讨，并提出第三方物流几种可行的战略选择。 2 我国第三方物流业存在的主要问题 (一)我国策三方物流企业与国外第三方物流企业的差距较大，具体表现在以下几个方面： 1、规模经济及资本差距明显。由于国外的大型第三方物流企业从全球经营的战略出发，其规模和资本优势是毫无疑问的，尤其初创时期的我国策三方物流业，本身的规模就很小，国外巨头雄厚的资本令国内企业相形见绌。 2、我国策三方物流业企业提供的物流服务水准及质量控制远不如国外同行。当国内一些企业还在把物流理解成“卡车加仓库“的时候，国外的物流企业早已完成了一系列标准化的改造。同时，国外的物流组织能力非常强大，例如德国一家第三方物流公司，公司各方面的物流专家遍布欧洲各地。如果有客户的货物需要经达不同的国家，那么欧洲各地的这些专家就在网上设计出一个最佳的物流解决方案。这种提供解决方案的能力就是这第三方物流公司的核心能力，而不像国内公司号称拥有多少条船，多少辆车。 3、我国加入 WTO 后物流产业的门槛降低。在物流服务业方面：我国承诺所有的服务行业，在经过合理过渡期后，取消大部分外国股权限制，不限制外国服务供应商进入目前的市场，不限制所有服务行业的现有市场准入和活动。同时在辅助分销的服务方面也作出了类似的承诺。这些方面的限制将在以后 3—4 年内逐步取消，在此期间，国外的服务供应商可以建立百分之百的全资拥有的分支机构或经营机构，国内物流服务业将直面国际竞争。 (二)资源浪费严重，第三方物流效率不高。 从微观上看，由于受计划经济体制的影响，长期以来许多企业，尤其是国有企业走的是“大而全”、“小而全”的路子，它们拥有自己的仓库、车队、甚至远洋船队，造成物流过程的大量浪费，具体表现为仓库的闲置，物流业经营分散，组织化程度低，横向联合薄弱。而能够提供一体化、现代化、专业化、准时化、高效服务的第三方物流企业则很少。从宏观上看第三方物流未能跟上经

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。
