【正文】 于成熟，多家汽車公司已經具備批量生產能力，多款電動汽車已經上市。法國：法國政府不僅采用多項政策優(yōu)惠方案，“買環(huán)保汽車享受高額補貼”等鼓勵市民使用電動汽車，法國政府還將投入4億歐元，用于包括電動汽車在內的清潔能源汽車研發(fā)。奧巴馬明確表示，美國政府計劃投入數(shù)十億美元用來推動插入式混合動力汽車的發(fā)展，目標是在2015年有100萬輛電動汽車投入使用。日前，美國加利福尼亞州Santa－Monica市政府在SantaMonica修建了一座極具未來感的太陽能充電站。為方便市民出行，巴黎市政府擬出了一張“充電站分布圖”，市民可以輕松地根據(jù)該圖找到最近的充電站。法國:　　巴黎是最早將清潔能源汽車引入公交系統(tǒng)的城市。 日本:據(jù)報道，以色列和日本都希望通過制訂明確的電動汽車充電站建設計劃，幫助電動汽車在本國早日實現(xiàn)商業(yè)化。在金融危機下，它更成為拉動汽車產業(yè)、刺激經濟復蘇的重要一環(huán)。h/L）循環(huán)壽命（次）鉛酸電池3513090500鎳鎘電池5517094500鎳氫電池802251431000鋰離子電池1201803601200磷酸鐵鋰電池120902102000燃料電池50060充電系統(tǒng)對于實際的電動汽車而言是不可缺少的支撐系統(tǒng)，同時電力企業(yè)作為關系國家能源戰(zhàn)略和國民經濟命脈的國有骨干企業(yè)，大力推動電動汽車的發(fā)展、充電站樁的建設具有重大意義。高鐵電池就是以高價鐵鹽 陰極材料如：高鐵酸鋇、高鐵酸鉀構成的水系電化學電池體系。目前，越來越多的研究人員選用鋰離子電池作為電動汽車的動力電池，因為鋰離子動力電池有以下優(yōu)點：工作電壓高（是鎳鎘電池氫鎳電池的3倍）； 比能量大（可達165WH/㎏，是氫鎳電池的3倍）；體積??；質量輕；循環(huán)壽命長；自放電率低；無記憶效應；無污染等。純電動汽車的最大瓶頸是電池。經過近十年的發(fā)展，我國電動汽車的研發(fā)取得明顯進展。特別在電動汽車領域，我國企業(yè)在關鍵的電池技術上獲得了突破，具備了率先啟動產業(yè)化的條件，有實現(xiàn)跨越的機會。電動汽車詳細可分為三類：即僅以車載蓄電池（或電容）為動力源的純電動汽車，以多個車載動力源提供動力的混合動力電動汽車（當前主要是指以內燃機及蓄電池）和以燃料電池為動力的燃料電池汽車。電動汽車在環(huán)保、清潔、節(jié)能等方面占據(jù)明顯的優(yōu)勢，據(jù)相關統(tǒng)計，污染物排量僅為普通內燃機車的2－8%，基本無污染物排放。At last firemen have put out a big forest fire亞運村電動汽車充電樁技術方案廣州南方電力集團科技發(fā)展有限公司2010年1月第一部分 充電樁發(fā)展的現(xiàn)狀 目前，珍惜地球上有限的石油資源，保護人類賴以生存的自然環(huán)境，減少溫室氣體排放量，遏制全球變暖趨勢已經成為全世界各國面臨的共同話題。 This is the prettiest carpet I have ever seen,39。We are going back now,39。 I said. 39。 I forgot to put you off.39。 Is this Woodford Green ?39。ll have to get off here,39。I sat in the front of the bus to get a good view of the countryside. After some time, the bus stopped. Looking round, I realized with a shock that I was the only passenger left on the bus. 39。m going to Woodford Green,39。I love travelling in the country, but I don39。 had put it on the floor, he promptly went to sleep again.When a plane from London arrived at Sydney airport, workers began to unload a number of wooden boxes which contained clothing. No one could account for the fact that one of the boxes was extremely heavy. It suddenly occurred to one of the workers to open up the box. He was astonished at what he found. A man was lying in the box on top of a pile of woollen goods. He was so surprised at being discovered that he did not even try to run away. After he was arrested, the man admitted hiding in the box before the plane left London. He had had a long and unfortable trip, for he had been confined to the wooden box for over ten hours. The man was ordered to pay amp。 Only 25 per cent a thief now!39。The whole village soon learnt that a large sum of money had been lost. Sam Benton, the local butcher, had lost his wallet while taking his savings to the postoffice. Sam was sure that the wallet must have been found by one of the villagers, but it was not returned to him. Three months passed, and then one morning, Sam found his wallet outside his front door. It had been wrapped up in newspaper and it contained half the money he had lost, together with a note which said: 39。The strap needsLesson43 Over the South Pole 飛越南極dance39。And a woman can39。Lesson57 Can I help you, madam? 你要買什么，夫人？A few cars, however, pleted the race. The winning car reached a speed of forty miles an hourmuch faster than any of its rivals. It sped downhill at the end of the race and its driver had a lot of trouble trying to stop it. The race gave everyone a great deal of pleasure. It was very different from modern car races but no less exciting. A woman in blue jeans stood at the window of an expensive shop. Though she hesitated for a moment, she finally went in and asked to see a dress that was in the window. The assistant who served her did not like the way she was dressed. Glancing at her scornfully, he told her that the dress was sold. The woman walked out of the shop angrily and decided to punish the assistant next day. She returned to the shop the following morning dressed in a fur coat, with a handbag in one hand and a long umbrella in the other. After seeking out the rude assistant she asked for the same dress. Not realizing who she was, the assistant was eager to serve her this time with great difficulty, he climbed into the shop window to get the dress. As soon as she saw it, the woman said s many ties.39。t have too many hats,39。 slowly. It obviously could not tell the difference between Indian music and jazz!In 1929, three years after his flight over the North Pole, the American explorer, R. E. Byrd, successfully flew over the South Pole for the first time. Though, at first, Byrd and his men were able to take a great many photographs of the mountains that lay below, they soon ran into serious trouble. At one point, it seemed certain that their plane would crash. It could only get over the mountains if it rose to 10,000 feet. Byrd at once ordered his men to throw out two heavy food sacks. The plane was then able to rise and it cleared the mountains by 400 feet. Byrd now knew that he would be able to reach the South Pole which was 300 miles away, for there were no more mountains in sight. The aircraft was able to fly over the endless white plains without difficulty. mending,39。A thief, yes, 39。 In time, all Sam39。345 for the cost of the trip.
