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

这些体是由盐、、化和二化混合而成致命混合物。

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，他们在地球云层中发现了化。

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，一束化似乎正在消失。

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

石油和天然作用在石灰岩中产生了化。

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

化与流过岩石雨水中反应。

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化体。

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在化。

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

他们还在监测空中化和二化痕迹。

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

这些沉积物是或含量很低，并且它们充满了化。

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

因此，在这种情况下，化可能在化还原反应中失去了电子。

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

木星大层中也有少量化。

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海藻中释放出高浓度化体。

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

在深海、黑暗海洋生态系统中，一些细菌使用化等化学物质作为它们能量供应。

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，在更远行星上，化会更难被发现。

In the aquifer's depths, a layer of clear fresh water sits atop salt water that's saturated with toxic hydrogen sulfide.

在含水层深处，一层清澈淡水就浮在充满有毒化咸水之上。

Like hydrogen sulfide, which smells like rotten eggs.

比如化，闻起来像臭鸡蛋。

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

同样，在这种情况下，它将沉积物中化还原剂与靠近表面化剂连接起来。

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

化是闻起来像臭鸡蛋无色体。

New observations by NASA's James Webb Space Telescope suggest that this is the first exoplanet where hydrogen sulfide has been identified.

美国航天局（NASA）詹姆斯·韦伯太空望远镜新观测结果表明，这是首次在系外行星上发现化。

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

在下水道情况下，细菌会将常见化合物分解，使其转化为化——这便是臭鸡蛋味来源。
