所以在构建测试夹具和进行弱电流及高阻抗连接时，尽量减少绝缘体之间及导体之间的接触也是很重要的。
Therefore, it's important to minimize contact between insulators as well as conductors in constructing test fixtures and connections for low current and high impedance.
没有绝对的绝缘体也没有绝对的导体，因为一切物体对电流都有阻力。
There exist neither perfect insulators nor perfect conductors, for all substances offer opposition to the flow of electric current.
当撤去电压时，这些分离的电荷在重新组合时会在与绝缘体相连的电路中产生衰减的电流。
When the voltage is removed, the separated charges generate a decaying current through circuits connected to the insulator as they recombine.
