How Magnetic Levitation Trains Float
磁悬浮列车如何实现悬浮
-
Maglev trains float above tracks using powerful magnets.磁悬浮列车利用强磁力悬浮于轨道之上。
-
Opposite magnetic poles attract, while like poles repel.异极相吸，同极相斥。
-
Electromagnets on the train and track push each other away.列车与轨道上的电磁铁相互排斥。
-
This creates a cushion of air with no physical contact.由此形成无实体接触的空气垫。
-
No wheels means less friction and very high speeds.无需车轮，摩擦更小，速度极高。
-
The train moves smoothly without engine noise or smoke.列车运行平稳，无引擎噪音和尾气。
-
Japan and China already run public maglev lines.日本和中国已开通公共磁悬浮线路。
