A spark discharge between two electrodes produces an "ionised gas tube" in the xenon gas-filled lamp piston through which electric current flows which in turn causes the gas to light up.

在充满氙气的灯柱中的两个电极之间进行火花放电将产生“电离气体管”，电流通过该管流动，从而导致气体发光。

Discharge tube: a closed insulating vessel containing a gas at low pressure through which an electric current flows when sufficient voltage is applied to its electrodes.

放电管：装有低压气体的封闭绝缘容器，当电极有足够的电压时，通过它电流就开始流动。

Last month, the most exciting news was from UCLA, where a small team of researchers developed a micro-scale graphene-based supercapacitor that can charge and discharge a hundred to a thousand times faster than current batteries.
