Researchers have long been trying to explain the origin of the ammonia that triggered the formation of the first biomolecules on Earth.
在那里或许有些奇怪的化学成分是开普勒望远镜没能看到的。 这个温度太热了不能形成氨云，氨云可以反射一部分入射辐射，如木星上便是如此。
That’s too hot for the formation of ammonia clouds that would reflect some of that incoming radiation as they do on Jupiter.
“这是可能的”，他在美国宇航局的网站说，“在SEB的顶部形成了一些'氨的卷云，隐藏了SEB，才使我们不能看见”。
"It's possible," he said on the NASA website, "that some 'ammonia cirrus' has formed on top of the SEB, hiding the SEB from view."
通过大气层中水蒸气的冷凝作用形成了云，凝结在成簇的氨分子和硫酸分子周围。
Clouds are formed by the condensation of water vapour in the atmosphere around clusters of molecules such as ammonia and sulphuric acid.
可以用望远镜看到这颗行星的奶油色云带。它是由漂浮在土星大气层中的氨晶体形成的。
With a telescope, you can see the planet's cream-colored cloud bands, which are caused by ammonia crystals floating in its atmosphere.

Researchers have been trying to explain the origin of the ammonia that triggered the formation of the first biomolecules on Earth.
在畜牧场，氨是由生物降解形成的。
血红蛋白里的铁元素会和发光氨里的化学发生反应。意思就是说它里面的原子会重组并形成新的分子。
The iron in hemoglobin causes the chemicals in luminol to react, meaning that their atoms rearrange to form new molecules.
结果表明，以乙醇为碳源形成的好氧颗粒污泥脱氮性能不佳，氨氮的去除率在整个好氧颗粒化的过程低于30%。
The results indicated that the nitrogen removal rate by aerobic granules was no more than 30% when ethanol was the organic carbon source.
奥尔顿怀疑是木星全球风的模式改变将富含氨的物质带到了SEB之上的清澈而寒冷的区域，为在高空形成冰云打下了基础。
Orton suspects that changes in global wind patterns have brought ammonia-rich material into the clear, cold zone above the SEB, setting the stage for formation of the high-altitude, icy clouds.
腐植酸尿素降低氨挥发量与其养分释放模式和形成的土壤环境密切相关。
The ammonia volatilization reduction of humic acid urea correlated significantly with its nutrient-release mode and soil ambient.
在木星上，可以形成类似的卷云，只不过冰晶中的水(H20)变成了氨(NH3)。
On Jupiter, the same sort of clouds can form, but the crystals are made of ammonia (NH3) instead of water (H20).
从而得出结论：投加晶种可明显提高氨氮的去除率，但对形成大粒径晶体的影响不大。
Then, the effects of ammonia-nitrogen removal rate, particle type, particle diameter and component are analyzed.
同全氢气氛相比较，氨分解气氛更有利于50aw 600无取向硅钢有利织构的形成。
Compared with pure hydrogen atmosphere, decomposed ammonia atmosphere is more propitious to the formation of advantaged texture of non-oriented silicon steel.
