1·The emission of sulfur dioxide when high-sulfur coal is burned is restricted by law.
高硫煤燃烧过程中的二氧化硫的排放是受到法律限制的。
2·The level of sulfur dioxide gas above Venus's clouds shows large and very frequent fluctuations.
金星云层上方的二氧化硫气体水平显示出巨大且非常频繁的波动。
3·It is quite possible that these fluctuations, the huge increase and decrease of sulfur dioxide, happening again and again.
很有可能这些波动，二氧化硫的大量增加和减少，一次又一次地发生。
4·New coal-burning plants usually comply with the law by installing expensive equipment to filter sulfur dioxide from their emissions.
新的燃煤电厂通常安装昂贵的设备来过滤排放的二氧化硫以遵守法律。
5·Sulfur dioxide, a major contributor to acid rain, is an especially serious pollutant because it diminishes the respiratory system's ability to deal with all other pollutants.
二氧化硫是酸雨的主要成因之一，它是一种特别严重的污染物，因为它会降低呼吸系统处理其他污染物的能力。
6·Instead of lava, ash, and sulfur dioxide, these volcanoes spew mud and methane.
这里的火山喷涌出的不是岩浆、火山灰和二氧化硫，而是泥浆和甲烷。
7·Renewable diesel also creates far fewer sulfur dioxide, particulate, and nitrogen oxide emissions.
同时，可再生柴油排放的二氧化硫物、颗粒物和氮氧化物等要小得多。
8·That seemed to be the case with sulfur dioxide (SO2), which has a longer lifetime in the atmosphere.
二氧化硫(SO2)或许就是这样的例子，因为它在大气中存在的时间更长。
9·Vegetation in the surrounding area has been destroyed by acid rain due to high sulfur dioxide emissions.
二氧化硫的高排放引起的酸雨使得周围的植物遭到大面积破坏。
10·One theory suggests the Deccan lavas spewed immense amounts of poisonous sulfur dioxide gas into the atmosphere.
有一种假说认为，徳干火山喷发出的大量二氧化硫有毒气体进入了大气。

4·Other issues, Trenberth says, are the cost and the location: Should sulfur dioxide seeding be global, or more localized to target specific parts of the planet?
其他问题，还包括成本和定位：是应该进行全球性撒播二氧化硫，还是定位后投射到特定目标区域？
5·They recommend revised limits for the concentration of selected air pollutants: particulate matter (PM), ozone (O3), nitrogen dioxide (NO2) and sulfur dioxide (SO2), applicable across all WHO regions.
它们为下述选定的空气污染物的浓度限值提出了修订：可吸入颗粒物(PM)、臭氧(o3)、二氧化氮(NO2)和二氧化硫(SO2)，适用于世卫组织所有区域。
