These gases are a death filled cocktail of hydrochloric acid, hydrogen, hydrogen sulfide, and sulfur dioxide.

这些体是由盐酸、氢、硫化氢和二氧化硫混合而成的致命混合物。

Second, it's about what scientists say they've detected in the planet's clouds, hydrogen sulfide.

其次，这是科学家所说的，他球的云层中发现了硫化氢。

The main toxic gases are carbon monoxide, carbon dioxide, hydrogen sulfide, and nitrogen oxide.

主要有毒体是一氧化碳、二氧化碳、硫化氢和氮氧化物。

The hydrogen sulfide reacted with oxygen in rainwater moving through the rock.

硫化氢与流过岩石的雨水中的氧反应。

The action of oil and natural gas created hydrogen sulfide in the limestone.

石油和天然的作用石灰岩中产生了硫化氢。

To test the device, the researchers puffed it with different concentrations of hydrogen sulfide gas.

为了测试这个设备，研究人员使用了不同浓度的硫化氢体。

At super high concentrations, it can be toxic like hydrogen sulfide.

浓度下，和硫化氢一样有毒性。

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

硫化氢是闻起来像臭鸡蛋的无色体。

Jupiter, too, has small amounts of hydrogen sulfide in its atmosphere.

木星的大层中也有少量的硫化氢。

But the exoplanet was previously not thought to hold hydrogen sulfide.

但是，这颗系外行星此前被认为并不存硫化氢。

They're also monitoring the air for traces of hydrogen sulfide and sulfur dioxide.

他还监测空中硫化氢和二氧化硫的痕迹。

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

但是，当他观察烧杯时，一束硫化氢似乎正消失。

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，并且它充满了硫化氢。

It warned some communities about high levels of hydrogen sulfide gas escaping from the rotting algae.

它警告一些社区注意从腐烂的海藻中释放出的浓度的硫化氢体。

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，一些细菌使用硫化氢等化学物质作为它的能量供应。

Hydrogen sulfide, on the other hand, affects the nervous system causing dizziness and pain in the respiratory system.

另一方面，硫化氢影响神经系统，引起头晕和呼吸系统疼痛。

Like hydrogen sulfide, which smells like rotten eggs.

比如硫化氢，闻起来像臭鸡蛋。

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

因此，这种情况下，硫化氢可能氧化还原反应中失去了电子。

Like, in this case, it connects the hydrogen sulfide reducers in anoxic sediment with oxidizers closer to the surface.

同样，这种情况下，它将缺氧沉积物中的硫化氢还原剂与靠近表面的氧化剂连接起来。

He noted, for example, that hydrogen sulfide would have been much harder to find on planets that are further away.

他指出，例如，更远的行星上，硫化氢会更难被发现。
