Calculations of reactions about the chemistry of nitric oxides and ozone were performed to study the effect of NOX emission in the stratosphere. They were conducted with parameters in the stratosphere. In addition, sensitivity analysis was performed to study the mechanism of their reactions. Measurements of NOX under an emission of a low-pressure mercury lamp were also conducted by NO and NO2-LIF method experimentally. A large evacuable chamber was used to simulate stratospheric condition. Numerical results and experimental ones were compared and chemical and photochemical reactions of NOX -ozone chemistry were discussed. As results, main reactions of ozone depletion by NOX and HOX were specified and simulation of reactions in the stratosphere was achieved qualitatively by laboratory-scale experiment.
