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.
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.
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.
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.
