中文:
电浆球内充填着低压的惰性气体,中央金属球接上高电压,通常是高频交流电或高频脉冲式直流电,其电压高达数千至一万伏特,频率则可能高达数十千赫,但电流小,可能小到一毫安培以下,由于电流过低,流经人体并不会有电击的感觉.电浆球内填充的气体为氪或氙与氖的混合气体,氪、氙使球内的光看起来比较像闪电的形状,而非气流形状.电浆球通电时,在中心金属球与玻璃外壳之间会有电流通过,带电粒子撞击到球内气体时,会发出各种颜色的光线,这一点和霓虹灯(其实应叫氖灯)非常类似.球内填充的气体种类不同,光线的颜色也不同,例如:氦-淡黄到橙;氖-暗红到橙;氮-白或粉红或橙;氩-紫;氪-白或灰,低压时绿;氙-蓝白或蓝灰,除气体种类外,电流大小及球内气压也会影响电浆球发出的颜色.
英文(软件翻译,凑活着看吧):
Filled with the low-voltage inert gas the electric thick liquid ball,the central metal game connects the voltage of climbing to a high place,it is usually high-frequency alternating current or high-frequency pulse-duct direct current,its voltage is up to between thousands of and 10,000 volts,frequency may be up to several dozen kilohertz,but the electric current is small,may get under a fine long hair ampere small,because the electric current is too low,flowing through the human body will have no feeling shocked by electricity.Gas that electric thick liquid pack in the ball krypton or xenon and mist of neon,krypton,xenon make light of ball seem,compare the form like the lightning,but not air current form.When the electric thick liquid ball is energized,there will be electric current that will be passed between metal ball of the centre and glass outer cover,when the charged particle is struck to the gas in ball,will emit the light of different colors,this with the neon lamp ' Should in fact call the neon lamp) Very similar.Gas kinds packed in the ball are different,colors of the light are different too,for example:Helium - Yellowish to get orange; Neon - Dark red to get orange; Nitrogen - White or pink or orange; Argon - Purple; Krypton - Green when being white or gray,low-voltage; Xenon - Blue and white bluish grey,besides gas kind,electric current size and ball atmospheric pressure can influence electric thick liquid that ball send out too.
