How to test for Nitrogen?
Turns out the nitrogen may have come from Earth.
Let me introduce you to Nitric Oxide.
Various forms of reaction for nitrogen cycling.
Turns out the nitrogen may have come from Earth.Combinations with other parts of speech
They are often rich in specific nutrients, such as nitrogen.
Without nitrogen, most of the world's crops wouldn't exist.
Carbon nitride: The structure of nitride carbon was proposed in 1985.
Significant reductions in nitrous oxide gas emissions are also expected.
Where do those nutrients, primarily nitrates and phosphates, come from?
Only the emissions of nitrogen and the sulphur oxides showed better results.
Can you use induction heating to braze steel parts in a nitrogen atmosphere?因此,氮氧化物是控制温室气体排放时(比如京都议定书)的主要对象。
Nitrous oxide is thus part of efforts to curb greenhouse gas emissions, such as the Kyoto Protocol.
To grow plants, including crops, nutrients such as nitrogen are naturally required.氮是帮助植物和牲畜生长的关键营养素,但它容易逃入环境(PDF).
Nitrogen is a key nutrient that helps plants and livestock grow, but it escapes readily into the environment(PDF).与ICE发动机相比,该团队估计燃气扩展器可以减少85%的氮氧化物排放。
When compared to an ICE engine, the team estimates that a gasrange extender can reduce emission of nitrous oxides by 85%.液态氮是储存和处理使用杜瓦,这是一种类型的壁容器,在墙壁之间的真空.
Liquid nitrogen is stored and handled using Dewars, which is a type of double-walled containers with a vacuum in between the walls.研究团队分析了这些生物对海洋中甲烷和氮氧化物的直接和间接贡献。
The team analysed both the direct andindirect contribution that these groups were having on methane and nitrous oxide production in the sea.与氮氧化物不同,氮氧化物在技术上也不是温室气体,但它们对大气有间接影响。
Unlike nitrous oxides, nitrogen oxides are again not technically greenhouse gases, but they do have an indirect effect on the atmosphere.该提案包括较低的氮氧化物(NOx)排放阈值,并将从2023年到2025年逐步控制需求。
The proposal includes lower thresholds for nitrogen oxide(NOx) emissions, and would phase in control requirements from 2023 to 2025.然而,一旦分子形成,富勒烯笼分离并稳定氮原子,因此合成的产物可被收集和储存。
Once the molecule is formed, however,the fullerene cage isolates and stabilizes the nitrogen atom, so the products synthesized can be collected and stored.诸如碳和氮等元素以及其他一些较重元素在这些恒星中形成并返回到星际介质中。
Elements such as carbon and nitrogen, as well as some other heavier elements, are created in these stars and returned to the interstellar medium.这些卡车排放的PM10和氮氧化物水平远低于当前欧洲标准,显著改善了空气质量。
The trucks will also emit levels of PM10 and nitrous oxides(NOx) well below current European standards, thereby significantly improving air quality.像二氧化碳、氮氧化物、甲烷和臭氧一样的气体属于重要的氧化剂,约占到空气的千分之一。
Gases like carbon dioxide, nitrous oxides, methane, and ozone are important oxidants that account for about a tenth of one percent of the atmosphere.这些活动将一氧化碳、二氧化硫和氮氧化物释放到大气中,从而会导致烟雾和各种健康问题的出现。
These activities release carbon monoxide, sulfur dioxide and nitrous oxide into the air, all of which contribute to development of smog and various health problems.液态氮是用于制冷廉价的低温液体,生物样品的保存和低温科学实验。
Liquid nitrogen being an inexpensive cryogenic liquid, is used for refrigeration, preservation of biological samples and for low temperature scientific experimentation.因此,提高农业氮效率和阻止土壤中氮的逸出可以极大地促进减缓气候变化的战略。
Increasing nitrogen efficiency in farming and stopping the escape of nitrogen from soil can therefore greatly contribute to climate change mitigation strategies.”.氮氧化物(NOx)的燃烧过程是现在主要的酸化和eutrophying空气污染物,如硫污染近几年在下降。
Nitrogen oxides(NOx) from combustion processes are now the main acidifying and eutrophying air pollutants, as sulphur pollution has fallen in recent years.".
