| 1. | Violent winds periodically drive clouds of dust around mars .
狂风间歇地席卷火星上的尘云。 |
| 2. | As contraction continues and the density increases, the dust becomes so thick at the center of the cloud that it absorbs the far-infrared radiation .
当收缩过程继续进行下去，密度不断增大时，气尘云中心的尘埃就会变得极其浓密，因而能够吸收远红外辐射。 |
| 3. | 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H区的原始气尘云残余。 |
