| 1. | As a new - style land vehicle , the magnetic levitation vehicles rely on electromagnetic forces to suspend the train on the railway and advance by linear synchronous motor . they can run placidly at high speed without wheels and transmission machines . since the magnetic levitation vehicles have low maintenance prices and circumstance pollution , they have favorable development foreground 作为新型的陆上交通工具,磁浮列车依靠电磁力将列车悬浮于轨道上,用直线电机推进,它没有车轮及相应的传动机构,与地面无机械接触,可以高速、平稳地运行,并且运营维护费用低,无环境污染,具有良好的发展前景。 |
