1·A long tendril of colder gas and dust extends many light years into the void from the receding ionization front.
低温气体和尘埃长长的卷须从渐行渐远的电离前沿一直延伸到数光年远的太空。
2·The low ionization potentials of the heavier gases also account for their chemistry.
较重的稀有气体具有较低的电离势，这也可以解释它们的化学性质。
3·The ionizing radiation from the high altitude burst can travel for hundreds of miles before being absorbed. Significant ionization of the upper atmosphere (ionosphere) can occur.
由高空爆炸产生的致电离辐射在被吸收之前能够传播几百英里，产生明显的高层大气电离(电离层)。
4·Radiofrequency waves are electromagnetic fields, and unlike ionizing radiation such as X-rays or gamma rays, cannot break chemical bonds nor cause ionization in the human body.
射频波就是电磁场，但是与X射线或伽玛射线辐射等电离辐射不同的是，射频波不会打破化学键，也不会给人体造成电离辐射伤害。
5·On the basis of the first ionization potentials of the gases, Kossel noted that xenon was most likely to have the capability of forming fluorides and oxides.
在稀有气体一阶电离势的基础上，科塞尔注意到：氙最可能形成氟化物和氧化物。
