Super capacitors or "electric double layer capacitors" store charge in a layer of ions adsorbed on the surface of carbon.
超电容器或者“双电介质层电容器”通过吸附碳层表面的离子储存电量。

Sensors detect when dust concentrations reach a critical level and then an electriccharge energises the material sending a dust-repelling wave across its surface.
当传感器发现粉尘浓度达到了临界水平，就有一定的电荷促使该材料发出除尘波越过其表面。

The polarity of impulse voltage and the polarity of insulator surfaceelectriccharge can affect the corona initial time of insulator, the change time - interval and the corona current.
