when the applied voltage

Similarly, in an ultracapacitor, when voltage is applied across the two metal plates (i.e. during charging), a charge still builds on the two electrodes—one positive, one negative.

同样，在超级电容中，当两块金属片被施以电压（即充电）后，电荷建立于两极，一极为正，一极为负。

When the microscope's sharp tip applied a positive voltage to the material's surface, it drew conducting lines that exist in the space between the oxide layers.

当显微镜的尖端把正电压施加到材料表面时，它就在氧化层之间的空白处画出了导线。

When a voltage is applied across the membrane, a strand of DNA is drawn into the pore.

当在膜一侧侧施加电压，DNA链就被拉进纳米孔。
