他们发现了一个不连续的一级相变，这个相变是在液态氢低电导率的分子态和高电导率的原子态之间。

They discovered a first order phase transition, a discontinuity, in liquid hydrogen between a molecular state with low conductivity and a highly conductive atomic state.

除了继续向捷豹供应发动机以及其他部件之外，福特还将提供其氢燃料以及低排放的动力系统技术。

As well as continuing to supply Jaguar with engines and other components, Ford will provide access to its hybrid and low-emission powertrain technology.

So when we talk about orbitals in multi-electron atoms, they're actually lower in energy than the corresponding h atom orbitals.

它们的能量实际上,比对应的氢,原子轨道要低。

And the reason we can see that by looking at this graph is that we see that nitrogen when it's bonded is in an even lower well than we saw for hydrogen.

原因可以通过观察这幅图发现,我们看到氮在成键之后将处于更低的势阱中,对氢而言。

So, in talking about covalent bonds, we should be able to still apply a more general definition of a chemical bond, which should tell us that the h 2 molecule is going to be lower in energy than if we looked at 2 separate hydrogen atom molecules.

那么，既然提到了共价键，我们应该还可以,给化学键下一个更普遍的定义,那就是告诉我们氢分子能量应该更低,与两个分开的氢的单原子分子相比。
