Violent winds periodically drive clouds of dust around Mars. 狂風間歇地席捲火星上的塵雲。
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. 當收縮過程繼續進行下去，密度不斷增大時，氣塵雲中心的塵埃就會變得極其濃密，因而能夠吸收遠紅外輻射。
In particular, neighbors complained of severe vibrations and heavy dust from blasting operations at the quarry. 特別值得一提的是，鄰近地區的人們抱怨的是採石廠爆破引起的嚴重震動和濃重塵霧。
