1·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。
2·Inspection should verify safety of bearing assemblies and integrity of insulators and conductors.
这项工作须检查轴承组件的安全性和绝缘体以及导体的完整性。
3·How big that charge is depends on the materials from which conductors and insulator are made, and also on their geometric configuration.
电荷的大小不仅取决于导体和绝缘体，还取决于它们的几何构造。
4·Then better ionic conductors and more promising designs emerged, and its popularity waned.
后来随着更好的离子导体和更多先进技术的出现，它的优势已逐渐消失。
5·They are to regular conductors what a laser beam is to a light bulb.
相比起来，超导体之于常规导体，就像一束激光之于一个灯泡。
