Violent winds periodically drive clouds of dust around Mars. 狂風(fēng)間歇地席卷火星上的塵云。
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(guò)程繼續進(jìn)行下去，密度不斷增大時(shí)，氣塵云中心的塵埃就會(huì )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采石廠(chǎng)爆破引起的嚴重震動(dòng)和濃重塵霧。
