全球将掀起磁悬浮列车热天赐美国：发明在先实施在后早在３０多年前，美国的两位年轻科学家就设计出一种利用磁悬浮技术的运输方式，根据他们的设想，强大的磁场会将火车提升至离导轨几英寸的地方，然后以时速４８０余公里行驶，与轨道不发生摩擦。他们的这一设想在一家学... The world will set off Maglev train hot weather to the United States: the invention implemented in the early As early as 30 years ago, two young scientists in the United States to design a magnetic levitation technology based on the mode of transport, according to their vision, a strong magnetic field will train Raised a few inches from the rail, and then traveled at speeds of over 480 kilometers per hour, with no friction with the track. Their idea in a school ...
