But, as they watched the beakers, a bunch of the hydrogen sulfide seemed to be disappearing.

但是，当他们观察烧杯时，化氢似乎正消失。

In deep, dark ocean ecosystems, some bacteria use chemicals like hydrogen sulfide as their energy supply instead.

深海、黑暗的海洋生态系统中，些细菌使化氢等化学物质作为它们的能量供应。

These sediments were anoxic, or poor in oxygen, and they were also full of hydrogen sulfide.

这些沉积物是缺氧的或含氧量很低的，并且它们充满了化氢。

So, in this case, the hydrogen sulfide could have lost electrons in a redox reaction.

因此，这种情况下，化氢可能氧化还原反应中失去了电子。

Hydrogen sulfide is a colorless gas that smells like rotten eggs.

In a sewer's anaerobic conditions, common sulfate compounds are reduced by bacteria to hydrogen sulfide—the source of that rotten egg smell.

下水道缺氧的情况下，细菌会将常见酸化合物分解，使其转化为化氢——这便是臭鸡蛋气味的来源。

This makes them very resistant to hydrogen sulfide and anoxia!

这使它们非常耐化氢和缺氧！

Fart smells are actually due to a handful of compounds that contain sulfur: hydrogen sulfide, methanethiol, and dimethyl sulfide.

The clouds are made of methane, ammonia, and hydrogen sulfide — that last one is what makes rotten eggs smell so bad.

这些云团是由甲烷，氨和化氢组成的——由于有化氢，因此它就像臭鸡蛋样闻起来很臭。

In doing so, they also produce gases like carbon dioxide and methane, sulfurous compounds called mercaptans, and hydrogen sulfide, which eventually... pass.

这样做的过程中，它们还会产生二氧化碳和甲烷等气体，称为醇的亚酸化合物和化氢，最终通过。
