2.氮的氧化物在大气中存在的氮的氧化物,有一氧化二氮(N_2O)、氧化一氮(NO)、和二氧化氮(NO_2)。由于细菌的微生物学作用,一氧化二氮在土壤中形成,其既存在于对流层也存在于平流层。在自然环境中,其存在的浓度平均为0.32ppm。而氧化一氮是
2. Nitrogen oxides Nitrogen oxides present in the atmosphere are nitrous oxide (NO2), nitric oxide (NO), and nitrogen dioxide (NO2). Nitrous oxide is formed in the soil due to the microbiological effect of bacteria, which is present both in the troposphere and in the stratosphere. In the natural environment, its average concentration is 0.32ppm. Nitric oxide is
