A hydrogen explosion had also occurred earlier at reactor 2. That brings the number of crippled units to four of the plant's six reactors.

2号反应堆此前也发生过氢气爆炸，这意味着核电站6个反应堆中受损数量升至4个。

If the co 2 extracted from the atmosphere were combined with hydrogen (extracted from water using electrolysis), it could make synthetic hydrocarbon fuels.

如果我们能将从大气分离出的CO 2与氢(通过电解水得到)结合在一起，就能制造出人工合成的碳氢化合物燃料。

Hydrogen collected in the secondary containment buildings, where it exploded, blowing the tops off units 1 and 3, and damaging the cooling system of unit 2.

氢气在第二层安全壳内聚集，最终爆炸，将1号和3号的顶盖炸飞，损毁了2号的冷却系统。

When we increase the potential between the 2 electrodes that we have in the tube -- we actually split the h 2 into the individual hydrogen atoms, and not only do that, but also excite the atoms.

当我们增大两个电极之间电压,我们有-我们可以把氢气2,分解成单个的氢原子，不仅这样，还能激发原子。

For example, for the 2 s, again what you see is that the multi-electron atom, its 2 s orbital is lower in energy than it is for the hydrogen.

举例来说对于2s轨道，在多电子原子，中可以看到,它的2s轨道的能量低于氢原子的。

It has long been known that some solid materials, called metal hydrides, are capable of storing small amounts (about 1-2% of their own weight) of hydrogen at room temperature.
