In the case of very low electron density, the energetic electron region and the runaway region emerge.
在低密度情况下出现高能电子区和逃逸区。
Ionized by energetic starlight, a hydrogen atom emits the characteristic red H-alpha light as its single electron is recaptured and transitions to lower energy states.
氢原子被高能的恒星光离子化之后，在它的单个电子重新被捕获并跃迁到低能级上时会放出典型的红色h - alpha光。
The energy of light varies across the spectrum (blue light is more energetic than red) but only a certain amount of energy is needed to knock an electron free.
光谱中光的能量是不同的(蓝光比红光更具能量)，但是只需一种确定的能量来碰触电子使其脱离。
The silicon absorbs sunlight and passes energetic, negatively charged electrons and positively charged electron vacancies to the catalysts on opposite sides that use them to make H2 and O2.
硅可以吸收光能，传导带正电荷和带负电荷的空位子到催化剂中，从而催化产生氢气和氧气。
