测量每相导体与金属屏蔽、金属套间的绝缘电阻。
Measure each phase conductor to metal mask and to metal sleeve insulation resistance.
绝大多数金属都是电的良导体，而纸张、空气、玻璃则是良好的绝缘体。
Most metals are good conductors of electricity, while paper, air and glass are good insulators.
这种新材料是导体还是绝缘体？
导体可说是不良绝缘体，因为它的电阻很低。
A conductor is a poor insulator because it has a low resistance to such flow.
显然“拓扑绝缘体”对这种神奇导体来说是个奇怪的的名字。
"Topological insulator" is an odd name for a wonder conductor.
