Furthermore, the stronger the trap( the more tightly the atoms are squeezed into a small volume), the faster and more efficient the cooling.
此外，阱越深（能让原子云挤在一个小空间里）冷却起来就越快越有效。

The nebulae, he said, were clouds of atoms and dust.
而星云，他说，是由原子和尘埃构成的云。
6.
This circumstance means that cool molecular gas is located there, a vestige of the original gas-dust cloud from which not massive stars were formed, spawning HII zones.
这种情形意味着那里有冷分子气体，它是形成大质量高温星、产生HⅡ区的原始气尘云残余。
