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。

So it's along the bond axis and it's between a carbon s p 2 hybrid, and then the hydrogen is just a 1 s orbital that we're combining here.

所以它是沿着键轴方向的,而且这里是一个碳sp2杂化轨道，和一个氢的1s轨道的结合,在这里我们可以合并他们。

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。

a0 This is equal to a sub nought for a hydrogen atom, and we remember that that's just our Bohr radius, which is . 5 2 9 angstroms.

它等于,我们记得，这就是波尔半径,也就是0，529埃，实际上。

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。

The nanotubes naturally cluster together into tiny bunches, and were found to be able to store 4.2% of their own weight of hydrogen.

ECONOMIST: Space-age soot

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.
