一氧化碳有很简单且独特的最外层轨道结构，两个并列的叶形从尖端的末梢伸出，一个带正相而另一个是负相。

Carbon monoxide has a simple but distinctive outermost orbital structure with two side-by-side lobes sticking out from the end of the tip, one with a positive phase and the other a negative phase.

在它的事件视界，即其边界，没有任何东西可以逃脱这头巨兽的引力，甚至连光也不行。 其引力相当于位于我们太阳系最外层行星轨道的海王星的四倍。

Its event horizon--theboundary at which nothing, not even light, can escape the monster’s gravitationalpull--is four times as large as the orbit of Neptune,our sun’s outermost planetary satellite.

最外层行星HD 40307 在“适居带”轨道上运转，在这片区域内，星球表面可能有类似地球的温度。

The outermost planet, HD 40307 g, orbits comfortably in the habitable zone, where Earth-like temperatures are possible.

This should make a lot of sense, because we know that a hydrogen has 1 s as it's outer-most or valence orbital, so it can be filled up just with two 1 s electrons.

这也是很合理的，因为我们,知道氢只有，1，s，轨道,这就是它最外层的轨道或者说价轨道，因此只要两个，1，s，电子就可以将它填满。

So basically, that means one electron in an s orbital in their outer-most most shell.

因此基本上,这意味着那个在，s，轨道上价电子是最外层的。
