Sulfate particles produced in combustion in the stratosphere may however reduce the effectiveness of NO2 as an agent of ozone depletion, adding further uncertainty to the calculation of the effect of stratospheric aircraft NO emissions on ozone depletion.

• 无论怎样，平流层中飞机由于燃料燃烧排出的含硫颗粒作为一种破坏臭氧的物质可以削弱氧化氮的作用，使得排除物氧化氮在平流层中对臭氧的破坏作用更加难以计算。
