My View on Developing the Car IndustryWith the development of modern industry，more and more families are able to have their own But，seeing the problems like air pollution and the reduction of resources，some people appeal for the reduction of private Still，I think there is every reason for the even faster development of the car Thanks to the development of the car industry， we do not have to cram in the buses， but can enjoy free travel in own cars， we can go to more places in a leisure Transportation becomes comfortable and But there are those who worry that too many cars may cause more traffic problems， serious:air pollution and the exhaustion ofresources， While these problems may be true， they can be solved and some are being For example， we can invent cars that: can save fuel or use other types of energy so that cars can still ＇be used even though resources run To reduce pollution， people have manufactured many cars without We can relieve the traffic pressure by building more and more roads or-adopt computer-monitored automated For all the contemporary problems cars bring， no one can deny the convenience cars bring us and ignore the effort We make to solve these Therefore，the development of the car industry is necessary， and it should develop as quickly as

多了打不下，自己扩充一下。Isn't it great when a plan comes together? A few months ago Beijing was fretting about an apparent collapse in demand for Muted sales data – sales of passenger cars fell 35 per cent between March and August – suggested that China would be lucky to get anywhere near its target of shifting 10m vehicles in Some pretty blunt instruments later – tax cuts and subsidies for smaller vehicles – and autos are flying off the With 7m new vehicles shifted in the first quarter (up 4 per cent year on year)， China has zoomed past the US (2m， down 38 per cent) as the world's largest At that run rate， Beijing will beat its 2009 target by early D No wonder this week's Shanghai auto show is more festive than equivalent events in the west， which are being scaled back or canned But delegates should keep some champagne on Automakers are not necessarily looking at better profits: minivans mean mini- Sales of vehicles with bigger engines are falling， as they are everywhere This year's overall improvement in sales is almost certainly linked to rampant credit growth， which the banking regulator last week said it was looking to And the industry continues to grapple with structural demand Take cars: sales growth averaged about 40 per cent a year in the six years to 2008， when annual growth slipped to 7 per Even with the punchy start， 2009 is set for about 5 per cent， estimates C For a country with third-world penetration – 32 cars per 1，000 people in 2007 (compared with 800 in the US) – that kind of growth is hardly Chinese savings rates are among the highest in the world， implying huge potential for But as Morgan Stanley points out， given off-book liabilities such as retirement， healthcare and education， the average consumer is practically in negative In spite of Beijing's inducements， households may continue to prioritise these invisible debts over a new set of 一项计划的出台不是很棒吗？几个月前，中国政府为汽车需求锐减而烦恼不已。从去年3月至8月，乘用车销量减少了35%。疲软的销售数据表明，中国要是能接近实现2009年销售汽车1000万辆的目标就算走运了。采取了一些相当直接的措施（对小排量汽车下调购置税并提供补贴）后，汽车销量急速上升。今年第一季度中国新车销量达270万辆，同比增加4%，超越美国（220万辆，同比减少38%）成为世界第一大汽车销售市场。以这种增长速度，中国政府在12月初就能完成2009年的目标。难怪与西方规模缩减或压缩在一起举行的同类展会相比，本周的上海车展更具节日的欢乐气氛。但参展代表们先别忙开香槟庆祝。汽车制造商不一定能实现更多利润：微型车意味着微利。和世界其它地区一样，大排量汽车的销量正在减少。今年销量的总体改善几乎必定与信贷的高速增长有关——中国银行业监管部门上周已表示将注意控制。而汽车制造业还要继续努力解决结构性需求问题。以轿车为例：截至2008年的6年里，轿车销量以每年40%的平均速度增长，但2008年放缓至7%。虽然开局有力，但据花旗(Citi)估计，2009年汽车销量增幅可能在5%左右。对于一个汽车普及率仅为第三世界水平的国家——2007年，每千人拥有32辆汽车，而美国每千人拥有800辆——这种增长根本算不上惊人。中国的储蓄率位居世界前列，意味着巨大的消费潜能。但正如摩根士丹利(Morgan Stanley)指出的那样，如果考虑到退休、医疗和教育等账外债务，中国普通消费者实际上是负资产。因此，尽管中国政府采取了一系列刺激措施，但与购置新车相比，老百姓可能还是会优先考虑那些无形的债务负担。

Electronic brakeforce distribution or EBD or EBFD is an automobile brake technology that automatically varies the amount of force applied to each of a vehicle's brakes， based on road conditions， speed， loading， Always coupled with anti-lock braking systems， EBD can apply more or less braking pressure to each wheel in order to maximize stopping power whilst maintaining vehicular [1][2] Typically， the front end carries the most weight and EBD distributes less braking pressure to the rear brakes so the rear brakes do not lock up and cause a [3]How ABS worksUnder heavy braking， vehicle wheels may lock- The anti-lock braking system (ABS) monitors wheel speeds and releases pressure on individual wheel brake lines， rapidly pulsing individual brakes to prevent lock- During heavy braking， preventing wheel lock-up helps the driver maintain steering Modern ABS has four individual brake lines for each wheel， enabling different braking pressure on different road For example， less braking pressure is needed to lock a wheel on ice than a wheel which on bare If the left wheels are on asphalt and the right wheels are on ice， during an emergency stop， ABS detects the right wheels about to lock and reduces braking force on the right wheels， helping to avoid lock-up and loss of vehicle How EBD worksAs per SAE technical paper #920646 - Buschmann et "The job of the EBD as a subsystem of the ABS system is to control the effective adhesion utilization by the rear The pressure of the rear wheels is approximated to the ideal brake force distribution in a partial braking To do so， the conventional brake design is modified in the direction of rear axle overbraking， and the components of the ABS are EBD reduces the strain on the hydraulic brake force proportioning valve in the EBD optimizes the brake design with regard to: adhesion utilization; driving stability; wear; temperature stress; and pedal "EBD may work in conjunction with ABS and Electronic Stability Control ("ESC") to minimize yaw accelerations during ESC compares steering wheel angle to vehicle turning rate using a yaw rate "Yaw" is the vehicle's rotation around its vertical center of gravity (turning left or right) If the yaw sensor detects more/less yaw than the steering wheel angle should create， the car is understeering or oversteering and ESC activates one of the front or rear brakes to rotate the car back into its intended For example， if a car is making a left turn and begins to understeer (the car plows forward to the outside of the turn) ESC activates the left rear brake， which will help turn the car The sensors are so sensitive， and the actuation is so quick that the system may correct direction before the driver ABS helps prevent wheel lock-up and EBD helps apply appropriate brake force to make ESC work

-- Scott Perl， Albuquerque， NM A: Auto racers have told us the main advantage in filling tires with nitrogen instead of ambient air is that nitrogen tends to maintain more consistent tire pressure over a wide range of As friction between the tire and pavement drives up the temperature， air with varying amounts of moisture content responds differently and can cause inconsistencies in tire While racing drivers are more likely to notice the advantages of nitrogen than everyday drivers， we haven't heard of any disadvantages to using Skeptics question the practice， noting that ambient air is about 80% nitrogen and that it expands and contracts at the same rate as pure A number of readers say there's no appreciable difference in how the tires will react if filled with nitrogen， especially in everyday Q: Is it safe to use cruise control in rain or on wet pavement? -- Scott Brake， Westminster， C A: Car makers often warn that cruise control should be used only in light traffic on open roads and in good There have been reports of accidents involving cruise control when the car lost traction -- or hydroplaned -- in slippery Some car makers warn that the steady throttle of cruise control -- like keeping one's foot on the gas -- could cause the wheels to spin when they hit a wet or icy patch of Car-company representatives say the cruise- control warnings reflect the fact that drivers should be particularly vigilant when conditions are less than ideal， and cruising along on what amounts to partial autopilot tends to lull some drivers into a false sense of Q: If an automobile manual suggests a certain weight oil (such as， 5W-30)， would adding a quart of a different weight oil (say， 10W-40) between complete oil changes damage the car's engine? -- Gil Ehrenkranz， Potomac， M A: Probably But today's engines generally are more precisely engineered than those of 20 or 30 years Many of us at some point have topped off our cars with whatever oil happened to be available without causing damage -- at least not that we know Auto makers， however， say modern engines can be more sensitive to a change in oil weight， and using the wrong oil， even in small amounts， can hurt an engine's performance and even cause Q: What is a sequential manual transmission? How does it differ from an automatic or a standard manual transmission? -- Harry J Jaffe， Germantown， T A: A sequential manual transmission is a gearbox that requires gear changes to be made in order (first to second to third)， instead of having a shift pattern with a lever that allows the driver to skip Motorcycles have used such transmissions for decades and racing cars began using them years ago because they allow quicker Shifting is usually done through levers， buttons or The sequential transmissions advertised today -- mainly in high- performance cars such as Ferraris， Aston Martins and some BMWs -- are technically manual transmissions， except that the clutch and the gear changes are controlled The advantage is that gear changes can be made more quickly and precisely than a human shifting the old-fashioned Traditionalists say the downside is that they simply aren't as much fun to drive and require less driver

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
