美国代写毕业论文:实现技术发展的创新

1827年,Anyos Jedlik开始制造电动马达。这包括提供通信器、转子和定子,一年之后,这项创新被用于驱动一辆小车(Dijk et al., 2013)。二十年来经过一系列的发展,创新达到了主要的高度,是最早发展的汽车之一。直到20世纪,铁路运输和电动汽车都被认为是很常见的交通工具,其中商用电动汽车占据了很大的市场份额。随着时间的推移,其商业用途的一般用途减少到专业的角色,如城市配送车辆,牵引车,救护车,叉车,平台卡车(Bakker et al., 2012)。在20世纪的大部分时间里,英国是全球道路上使用电动汽车最多的国家。人们使用电气化火车来运输煤炭,因为在煤矿的另一端,电动机没有使用宝贵的氧气。由于瑞士缺乏天然化石燃料,他们不得不迅速将铁路网络通电。最早的可充电电池似乎有利于电动汽车的使用。

电动汽车领域的一些发展导致了电动汽车的衰落。与电动汽车相比,道路基础设施的改善满足了里程增加的要求。此外,加州、俄克拉何马州和德克萨斯州发现了大量的石油储量,这进一步导致了可广泛获得的廉价汽油,使得以汽油为动力的汽车行驶更远的距离更便宜(Sierzchula et al., 2012b)。此外,以汽油为动力的汽车最终变得更容易操作,进一步导致了1912年查尔斯·凯特林发明了电动起动器。这就消除了用手摇曲柄发动汽油发动机的需要。由于消声器的使用,这些汽车所产生的噪音是完全可以忍受的。1897年,海勒姆·珀西·马克西姆发明了这种消声器。

The power of electric motive started in the year 1827 by Anyos Jedlik who built the initially viable and crude electric motor. This involved the provision of communicator, rotor and stator, and after a year, this innovation was used for powering a small car (Dijk et al., 2013). With a series of development since two decades, the innovation reached major heights, being among the earliest development of automobiles. Until the twentieth century, rail transport and electric cars were identified as commonplaces, with the market covered in major shares by commercial electric automobiles. With the passage of time, their commercial use of general purpose reduced down to the roles of specialists as urban delivery vehicles, tow tractors, ambulances, forklift trucks, and platform trucks (Bakker et al., 2012). For majority of the years of the 20th century, UK turned out to be the biggest user of electric vehicles on road all across the globe. There was use of electrified trains for the transportation of coal, as the motors had not been using precious oxygen across the mines. The absence of natural fossil fuels in Switzerland forced them for rapidly electrifying their network on rail. The earliest batteries that were rechargeable appeared to be favourable for being used in electric cars.

Several developments in the field of electric vehicles resulted in declining electric cars. Improved infrastructure of road held the requirement of increased ranges in comparison with the offer of electric cars. Also, major reserves of petroleum were discovered in California, Oklahoma, and Texas that further resulted in the broadly available affordable gasoline that made cars powered by gas cheaper for being operated to cover longer distances (Sierzchula et al., 2012b). Also, cars powered by gasoline ended up becoming easier for their operations further resulting in inventing electric starter in the year 1912 by Charles Kettering. This resulted in the elimination of need over a hand crank to start an engine by gasoline. The emission of noise by these cars turned out to be extremely bearable with the utilization of the muffler. This muffler was invented by Hiram Percy Maxim in the year 1897.
