1·Most others use the principle of an underwater windmill whose rotors are turned by the tide.
大多数其他的是利用水下风车的原理，水下风车的转子被潮汐所推动。
2·That distinguishes them from synchronous motors that use a permanent magnet in their rotors instead of a set of aluminium or copper conductors.
这就把它们和在转子处使用永磁铁而非一套铝或铜导体的同步发动机区分开来。
3·Over the past year, the price of neodymium has quadrupled, as electric motors and generators that use permanent magnets instead of electromagnetic windings in their rotors have proliferated.
去年，由于使用永磁体代替电磁线圈转子的电动马达和发电机数量激增，钕的价格也增长了三倍。
4·This suction effect increases wind speeds by up to 30 percent at each of the 95-foot-long rotors to boost electricity production.
这一抽吸效应使得经过每个长达95英尺的转子的时候风速增加30%，有利于电力生产。
5·As the rotors turn, they generate turbulence, like the wake of a speedboat motor.
转子转动时会产生紊流，就像快艇的发动机产生的尾迹。
