《新能源与磁悬浮在未来交通中的应用》》-毕业论文.doc

摘 要 文中阐述了我国经济发展取得了举世属目的成就，但是大气污染严重影响了我们的正常生活；能源有效利用率低及能源短缺严重制约了经济的可持续发展。我们必须开发出新能源和能耗低的交通工具。在这些客观条件下，氢能源和磁悬浮列车诞生了，氢能源具有清洁、高效、储量大的优点；而磁悬浮列车兼有飞机和火车的优点，而且能耗极低，而更具前景的则是它的升级版—真空磁悬浮列车。 在开发新能源方面，氢能源的制取和应用技术日益成熟，如此发展下去，21世纪将注定是以氢能源取代以碳为主要能源的时代。虽然氢能源有较多优点，但是氢能源不方便运输，更重要的是直接作为内燃机燃料的效率只有38%。我们只有将氢能源转化为电能，这样才能大大提高能源利用率，降低能耗。电能堪称是新能源和磁悬浮中间的桥梁，开发新能源、新能源的转化和磁悬浮技术的应用在未来交通运输中相当重要。磁悬浮列车能源利用率极高。并且它采用电力驱动，其发展不受能源结构，特别是燃油供应的限制，不排放有害气体，它具有快速、低耗、安全、经济、无污染等优点，发展磁悬浮列车势在必行。 关键词: 能源供应； 可持续发展； 氢能源； 磁悬浮列车； 真空管道运输 Abstract The paper indicates that China has achieved outstanding progress in its economy, but the air pollution seriously affects our normal life; Low energy effective utilization and energy shortages seriously restricts the sustainable development of the economy. We have to develop new energy and low energy consumption of transportation. Under these objective conditions, hydrogen energy and maglev train was born.Hydrogen energy has the advantages of cleanness,high efficiency and large reserve ; maglev train has the advantages of both planes and trains, and low energy consumption, but it is more promising its updated version - vacuum maglev train. In the development of new energy, making and application of hydrogen energy technology matures, so, the 21st century is destined to replace hydrogen with carbon as the main energy era. Although hydrogen energy has more advantages, but hydrogen is not easy to transport and directly as an internal combustion engine fuel efficiency is only 38%. We should have hydrogen energy into electrical energy, so as to greatly improve energy efficiency and reduce energy consumption. Electricity is the middle bridge of new energy and maglev. The development of new energy, new energy transformation and application of magnetic suspension technology is quite important in the future transportation. Maglev train energy utilization rate is extremely high.And it uses the electric drive, whose development is not affected by the ene
