这包括使用硫或硫化氢气溶胶，使二氧化硫形成云层，进而导致全球变暗。

This would involve using sulphur or hydrogen sulphide aerosols so that sulphur dioxide would form clouds, which would, in turn, lead to global dimming.

当然，寻找渗出硫元素的硫化氢分解微生物意味着我们在寻找与地球上观测到的生物进程相同的过程。

Of course, looking for hydrogen sulfide-eating microbes that ooze elemental sulfur means that we'll be looking for similar biological processes we observe on Earth.

“脱硫”是从被污染的气体中清除二氧化碳、硫化氢和其它污染物质，（由于污染气体有硫的味道往往被称为酸气），这项工作仅在美国就是一年一百二十亿的生意。

“Sweetening” is the removal of CO2, hydrogen sulfide and other contaminants from contaminated gas, (often called sour gas due to the sulphur smell), and is a $12 billion-year-business in the US alone.
