Efficient Cars

Over the last thirty years or so we have seen a gradual infiltration of foreign energy efficient cars into our m arket.

In North America the big three auto m anufacturers seem to have been pre-occupied with the large gas-guzzling automobiles. There have been som e sm aller cars built in N.A. but not particularly efficient or long lasting. It is just recently that we have seen General Motors (GM) replaced by Honda as the largest car m anufacturer in the world. The Big Three seem very reluctant to m ove away from the gasoline burning auto. A few years ago GM had an electric car in California that seem ed to have great potential but it was shelved.

Foreign cars are developing hybrid technology that blends gas burning with electric powered engines. Finally, GM is developing the Volt, an electric car coming out 2010. All three North American auto m akers have plans for electric or hybrid vehicles that are electric powered at lower speeds and for the first 40 to 65 miles without being recharged. They are planning to bring them to m arket in the next couple of years.

There are other innovations outside the big three. The ZENN - Zero Emissions No Noise, built in Quebec, is a totally electric car m ade for city use. It will go a maximum of 40 km per hour and will last about 2 hours before needing to be recharged. They are classified as a Low Speed Vehicle (LSV) and although approved by the Federal Governm ent the provinces have been slow to allow them to be licensed for street use. At this point British Columbia has approved their use. Quebec has approved their use in a few cities. They can be licensed in 45 American states. As a result m ost of these cars are built for export.

Another interesting development is the partnership between a French auto-m aker and Nissan of Japan to build an electric car to be m arketed in Israel. The project is to establish a network of battery charge and exchange depots for lithium-ion batteries throughout the country by 2011. Israel is considered ideal for such a project because the c ountry is sm all; thus long distance car travel is uncommon.

Over the last few decades there has been a gradual m ovement toward fuel efficiency and emission reduction. It would seem that the sudden increase in the cost of petroleum will acceleratethe developm ent of more energy efficient cars. This is particularly true in North Am erica, as the m arket for larger cars and trucks has very suddenly almost collapsed.

These developm ents have the advantage of reducing fuel costs for autom obile owners in the future. Another huge advantage will be the reduction of pollution in large cities.

Smart Cars Michio Kaku 1 Even the automobile industry, which has remained largely unchanged for the last seventy years, is about to feel the effects of the computer revolution.智能汽车米其奥·卡库即便是过去70年间基本上没有多少变化的汽车工业，也将感受到计算机革命的影响。 2 The automobile industry ranks as among the most lucrative and powerful industries of the twentieth century. There are presently 500 million cars on earth, or one car for every ten people. Sales of the automobile industry stand at about a trillion dollars, making it the world's biggest manufacturing industry. 汽车工业是20世纪最赚钱、最有影响力的产业之一。目前世界上有5亿辆车，或者说每10人就有1辆车。汽车工业的销售额达一万亿美元左右，从而成为世界上最大的制造业。 3 The car, and the roads it travels on, will be revolutionized in the twenty-first century. The key to tomorrow's "smart cars" will be sensors. "We'll see vehicles and roads that see and hear and feel and smell and talk and act," predicts Bill Spreitzer, technical director of General Motors Corporation's ITS program, which is designing the smart car and road of the future. 汽车及其行驶的道路，将在21世纪发生重大变革。未来“智能汽车”的关键在于传感器。“我们会见到能看、能听、有知觉、具嗅觉、会说话并能采取行动的车辆与道路，”正在设计未来智能汽车和智能道路的通用汽车公司ITS 项目的技术主任比尔·斯普雷扎预言道。 4 Approximately 40,000 people are killed each year in the United States in traffic accidents. The number of people that are killed or badly injured in car accidents is so vast that we don't even bother to mention them in the newspapers anymore. Fully half of these fatalities come from drunk drivers, and many others from carelessness. A smart car could eliminate most of these car accidents. It can sense if a driver is drunk via electronic sensors that can pick up alcohol vapor in the air, and refuse to start up the engine. The car could also alert the police and provide its precise location if it is stolen. 美国每年有大约4万人死于交通事故。在汽车事故中死亡或严重受伤的人数太多，我们已经不屑在报纸上提及。这些死亡的人中至少有半数是酒后开车者造成的，另有许多死亡事故是驾驶员不小心所导致。智能汽车能消除绝大多数这类汽车事故。它能通过会感测空气中的酒精雾气的电子传感器检测开车者是否喝醉酒，并拒绝启动引擎。这种车还能在遇窃后通报警方，告知车辆的确切地点。、管路敷设技术通过管线不仅可以解决吊顶层配置不规范高中资料试卷问题，而且可保障各类管路习题到位。在管路敷设过程中，要加强看护关于管路高中资料试卷连接管口处理高中资料试卷弯扁度固定盒位置保护层防腐跨接地线弯曲半径标等，要求技术交底。管线敷设技术中包含线槽、管架等多项方式，为解决高中语文电气课件中管壁薄、接口不严等问题，合理利用管线敷设技术。线缆敷设原则：在分线盒处，当不同电压回路交叉时，应采用金属隔板进行隔开处理；同一线槽内强电回路须同时切断习题电源，线缆敷设完毕，要进行检查和检测处理。、电气课件中调试对全部高中资料试卷电气设备，在安装过程中以及安装结束后进行高中资料试卷调整试验；通电检查所有设备高中资料试卷相互作用与相互关系，根据生产工艺高中资料试卷要求，对电气设备进行空载与带负荷下高中资料试卷调控试验；对设备进行调整使其在正常工况下与过度工作下都可以正常工作；对于继电保护进行整核对定值，审核与校对图纸，编写复杂设备与装置高中资料试卷调试方案，编写重要设备高中资料试卷试验方案以及系统启动方案；对整套启动过程中高中资料试卷电气设备进行调试工作并且进行过关运行高中资料试卷技术指导。对于调试过程中高中资料试卷技术问题，作为调试人员，需要在事前掌握图纸资料、设备制造厂家出具高中资料试卷试验报告与相关技术资料，并且了解现场设备高中资料试卷布置情况与有关高中资料试卷电气系统接线等情况，然后根据规范与规程规定，制定设备调试高中资料试卷方案。、电气设备调试高中资料试卷技术电力保护装置调试技术，电力保护高中资料试卷配置技术是指机组在进行继电保护高中资料试卷总体配置时，需要在最大限度内来确保机组高中资料试卷安全，并且尽可能地缩小故障高中资料试卷破坏范围，或者对某些异常高中资料试卷工况进行自动处理，尤其要避免错误高中资料试卷保护装置动作，并且拒绝动作，来避免不必要高中资料试卷突然停机。因此，电力高中资料试卷保护装置调试技术，要求电力保护装置做到准确灵活。对于差动保护装置高中资料试卷调试技术是指发电机一变压器组在发生内部故障时，需要进行外部电源高中资料试卷切除从而采用高中资料试卷主要保护装置。

Smart cars in the future life

Smart cars in the future life China is increasingly prosperous and strong. The possession of private cars is becoming more and more common. This brings obvious pressure to the public traffic system. What’s more, some Chinese have little sense in obeying traffic rules, which adds to the problem. As the computer revolution progresses,the smart cars and roads have made great development and put into use.The smart cars can see,hear,smell and talk.They have divers functions. They can reduce fuel consumption and pollution,enable travelers to save time and eliminate most of car accident. Researchers of smart cars and computerized highways have great hopes for its furure. There is no denying that our modern society is moving on four wheels. Owning a private car is a great thing. It makes going out more convenient and comfortable. But if my family has the plan to purchase a private car, to be frank, I will say “No”. To begin with, possessing a private car is really a financial burden for the average families. As to my family, purchasing a private car maybe beyond our financial ability. Not only the car itself is too expensive to afford, but also the cost of maintenance is too high. Although the convenience and mobility of a private car badly attract me, I will repress this desire when I think about the heavy loan that the wonderful thing may bring us. What’s more, a private car is not good for my family members’ health and safety. The last but not the least, the traffic accidents, energy crisis, noise and air pollution, congested parking and crowded streets will all become more serious social problems that give threat to people’s peaceful lives. In addition, the popularization of private cars may lead people to a luxurious and lazy life. All in all, though there are many favorable aspects to attract people to possess private cars, as far as my family is concerned, I don’t think it is very necessary and useful.
