摘要：

The photochemical conversion of small amounts Of SO2 into SO3 and, finally, H2SO4 aerosol in an atmospheric air flow with small admixtures of ozone has been studied experimentally. Ozone admixtures increase the SO2 oxidation rate by a factor of 2.5 to 3.0 when the SO2 concentration in air is 0.07 mol %. Theoretical estimations predict a stronger effect of ozone. This discrepancy between the observed and calculated data may be due to the flow temperature rise caused by irradiation.
