He sits in a fixed posture and bow and then levitates. 他用一种固定的姿势来坐着,弯下腰,然后轻轻地浮起。
The high-speed maglev train which levitates form track by magnetic force and moves by linear motors is a new way for modern transport technology. 高速磁浮列车利用磁力使车体悬浮于轨道上,并采用直线电机推进高速运行,是现代交通技术发展的一条新途径。
An active magnetic bearing ( AMB), which levitates a rotor by magnetic forces, is a type of novel bearings and has many merits over conventional mechanical bearings, such as no contact, frictionless, high-speed operation and so on. 主动磁力轴承(简称磁力轴承)是利用电磁力使转轴稳定悬浮的一种新型轴承,具有许多传统机械轴承无法比拟的优点,比如:无接触、无摩擦、高速运行等。
