越过田野的磁悬浮列车：磁悬浮列车与传统高速列车相比具备很多优势

Frains glide on magnetic fields

在过去二十年里，与其他高速列车相比具备明显优势的原型磁悬浮列车的运行速度高达400公里／小时。这些优势包括振动小、噪声小、摩擦小，能耗低以及空气污染小。但是，磁悬浮列车是未来的列车原型吗？

Prototype magnetically levitated （maglev） trains for the past two decades have travelled at speeds of up to 400kmph with apparently compelling advantages over their high speed counterparts. The advantages include less vibrations, noise, friction, energy consumption, and noise and air pollution. But have maglevs become the train of the future？
