pollution plume

基本解释

The rocket exhaust plume causes the effects of noise, smoke, flame and heat radiation, environment pollution and signal attenuation, etc. So it is important to study exhaust plume.
火箭羽流会造成噪声、烟雾、热辐射、环境污染和信号衰减等多种效应，因此研究排气羽流问题至关重要。
The horizontal distribution of the pollution plume was highly related with the direction of the groundwater flow and the vertical distribution was affected fairly by the samples' depth.
主要赋存于地下水中，其污染晕的平面分布与地下水流向显著相关，垂向分布与深度相关；
Now she's trying to correlate her findings with those of the two research teams operating on the other side of the Pacific , where at one point the pollution plume was larger than Japan .
现在，她正试图将她的研究成果和太平洋彼岸的两个研究小组的研究结果进行比较与对比，在那里的一个地方污染云团的面积比日本还大。
