Homogenous reaction between hydrogen sulfide and elemental lead vapor removes hydrogen sulfide efficiently as the hot coal gas left the carbonizer.

铅和硫化氢在离开炼焦室时，由于煤降低温度，又生成硫化铅。

Typically the green and purple sulfur bacteria live in that chemocline, enjoying the supply of H2S from below and sunlight from above.

绿硫与紫硫通常会生活在化变层中，同时享受下方源源不绝的硫化氢与上方充足的阳光。

So long as their balance remains undisturbed, the oxygenated and hydrogen sulfide–saturated waters stay separated, and their interface, known as the chemocline, is stable.

直到达成平衡、不互相干扰，充氧的海水与饱和硫化氢的海水彼分隔，而且两者间的界面「化变层」也稳定的。

With hydrogen sulfide and tetrapropylene as raw materials, TDM was synthetized by the one step process in the presence of acidic ion exchange resin.

摘要 以硫化氢和十二烯为反应原料，以酸性离子交换树脂为催化剂一步合成叔十二碳硫醇。

Some derive their carbon from inorganic sources, and their hydrogen from hydrogen sulfider or other inorganic compounds, while other bacteria may be photosynthetic or saprobic.

某些细从无机原料中获取碳源，从硫化氢或其他无机化合物中获取氢，而另一些细光能合成的或腐生的。

This paper introduces experiment clearing away hydrosulfuric and mercaptan in waste gas from industry and o-zone, retention period, catalyzer and so on influence on removal rates.

介绍了臭氧氧化法去除工业废中的硫化氢、硫醇的试验情况,考察了臭氧浓度、停留时间和催化剂等不同因素对去除率的影响。

The results show experiment have a higher removal rate and the last oxidize product of hydrothion and mercaptan is condensed state sulfide, could not be sulfur dioxide.

试验结果表明能达到较好的去除效果,硫化氢、硫醇的最终氧化产物可以不二氧化硫,而凝聚的硫化物。
