它可以在超导体（一种能导电的材料）和绝缘体（一种不导电的材料）之间转变。
It can change between a superconductor a material that conducts electricity, and an insulator a material that doesn't conduct electricity
带负电的电子趋于向正极集中，但无法通过不导电的绝缘体(多数时候，会有一些漏电)。
The negatively charged electrons want to join the depleted (positive) side, but can't cross over that non-conductive insulator (for the most part, anyway-there is some leakage).
绝缘层：涂于电极或挂具的某一部分，使该部位表面不导电的材料层。
Insulating layer: coating on the electrode or hanging fixture, a part of the surface of the part of conductive material layer.
