1. Nitrogen-oxide emissions during the cruising portions of the flight fell by around a quarter. 飞行中巡航部分的氮氧化物的排放量下降了四分之一左右。
2. When the new day dawns, natural sunlight quickly kills off these handy nitrogen-oxide molecules. 在新的一天破晓时，自然的阳光很快地消灭这些手边的氮氧化物分子。
3. The lights prevent production of a particular type of nitrogen-oxide molecule known as a nitrate radical, which forms from reactions of nitrogen dioxide with ozone. 这些照明灯阻止了一种特殊类型的二氧化氮水分子——它被认为是一种硝分子团——的生成，而二氧化氮水分子则是二氧化氮和臭氧的反应物。
4. Since nitrogen oxide compounds are components of smog and are common water pollutants, does nitrogen-enriched gasoline create additional pollution? 既然氮氧化物是烟尘成分的一种，也是常见的水污染物，那加氮汽油会不会产生额外的污染呢？
5. Renewable diesel also creates far fewer sulfur dioxide, particulate, and nitrogen oxide emissions. 同时，可再生柴油排放的二氧化硫物、颗粒物和氮氧化物等要小得多。
