The orbital complex was tracking northeastward, nearly parallel to the terminator, making it possible to observe an apparent "sunrise" located almost due north.

轨道正沿着西北方向，几乎和明暗分界线平行，这使得看到一个明显的正北方向的日出成为了可能。

So, I think we have these molecular orbital energies down, so let's move on to talking about more complex molecules.

分子轨道能量就说到这里，让我们继续来讨论一下更复杂的分子。

If all goes according to plan, by 2014 Bigelow will begin constructing an orbital space complex referred to as "Space Complex Alpha"--at least until he sells the naming rights.
