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。
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。
Some new results are given through investigation on threshold feature of the laser, effect of gas mixture ratio and discharge temperature on the laser output power etc.
通过研究铜空心阴极激光器阈值特性、气体混合比和放电温度对激光输出功率的影响，给出了一些新的结果。
