1·Maglev doesn't rely on the friction of wheels on track.
磁悬浮不依赖于车轮在轨道上的摩擦力。
2·The concept of rapid maglev travel, as this trick is known, is not new.
高速磁悬浮旅行的概念，就像这个绝技为人所知的那样，不是新的。
3·Magnetic levitation, or maglev, holds the ball in place while it spins around, getting clothes cleaner than a circular-spinning drum ever could.
磁力悬浮，或者磁悬浮，使这个旋转的球始终保持在同一位置，比循环滚动机器洗得更干净。
4·But maglev takes a load of hardware and a ton of power and is useless for small, simple kinds of engineering.
但是磁悬浮需要大量的硬件和能源，它在小而简单的工程上没有用处。
5·If Japan does not start selling maglev trains overseas, it risks losing its technological edge, Mr. Ieda warned.
如果日本放弃向海外推销磁悬浮列车，则可能导致失去技术优势的危险，家田先生警告说。
