硫化氢

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

气态铅和在离开炼焦室时，由于煤气降低温度，又生成铅。

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

绿菌与紫菌通常会生活在变层中，同时享受下源源不绝的与足的阳光。

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 以和十二烯为反应原料，以酸性离子交换树脂为催剂一步合成叔十二碳醇。

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，氧的海水与饱和的海水彼此分隔，而且两者间的界面「变层」也是稳定的。

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.

某些细菌从无机原料中获取碳源，从或其他无机合物中获取，而另一些细菌则是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.

介绍了臭氧氧法去除工业废气中的、醇的试验情况,考察了臭氧浓度、停留时间和催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,、醇的最终氧产物可以不是二氧,而是凝聚态的物。
