摘　　要：Photooxidation of the aromatic hydrocarbon toluene and its subsequent reactions were carried out using UV-irradiation of toluene/CH_(3)ONO/NO/air mixtures in a home-made smog chamber.The secondary organic aerosols could be formed after those oxidation products of semi-volatile or-ganic compounds were partitioned between gas phase and particle phase.The aerosol time of flight mass spectrometer(ATOFMS)was used to measure size and molecular composition of individual secondary organic aerosol particle.Size distribution and chemical composition of secondary organic aerosol were got in real time.
