We call these giant molecular clouds, because why not.

我们称这些为巨大的分子云，因为为什么不这么叫呢。

Perfect. That gives you two hours and 15 minutes for that dense molecular cloud of aromas to dissipate.

太好了，那你还有2小时15分让那片稠密的人造纤维分子云的香气消散。

These are also sometimes called molecular clouds; they're cold enough that atoms can stick together to form molecules.

这些云有时也被称为分子云；温度足够低，原子可以结合在一起形成分子。

It's actually just a bubble sitting on the edge of a much, MUCH larger molecular cloud, hundreds of light years across.

它实际上只是一个气泡，坐落在一个更大的分子云的边缘，分子云直径有几百光年。

The initial wave, the jam, may be started by some sort of disturbance in the disk, perhaps an overdense region created when a couple of giant molecular clouds smash together.

最初的波，也就是阻塞，可能是由磁盘中的某种扰动引起的，可能是一对巨大的分子云相撞时产生的一个密度过高的区域。
