如果碳纳米管阴极附近的真空度太低，将产生打火、气体电离、离子回轰阴极等问题，将导致阴极发射电流的迅速衰减。
If the vacuum near the cathode is too poor, it will generate spark, gas ionization and ion bombardment on cathode, which can result in a fast attenuation of the emission current.
等离子显示器是平板显示器中最好的一种，像霓光灯泡，等离子显示器在电流存在的情况下使用一种发光的气体。
A gas-plasmadisplay is the best type of flat screen. Like a neon light bulb, the plasma display uses a gasthat emits light in the presence of an electric current.
通过上述离子化过程会产生气体放电，从而使阻抗降低，放电电极之间就会有大量的电流流动，而产生较强的可视光。
The ionization will realize electric discharge of gas, so as to lower down the resistance, realize large amount of current flow between discharge electrodes and generates stronger visible light.
应用两种形式的励磁线圈，实测了五种型号的真空灭弧室内气体压强与磁控放电离子电流的关系曲线，并对试验结果进行了理论分。
