摘要
ＳＯ２与烷烃在３１３０高压汞灯辐照下生成光化学烟雾．实验测量了烟雾强度随ＳＯ２压力和烷烃压力变化的规律．文中提出的烟雾生成动力学模型较好地反映了这些实验规律，并得到ＳＯ２与丙烷、戊烷、己烷生成光化学烟雾速率常数ｋｐ２之比，以及它们的物理猝灭速率常数ｋｑ２之比．
Photochemical aerosols are formed in SO2-alkane mixture by a high pressure mercury lamp with 3130A radiation.The reltions of photochemical aerosol intensity to partial pressure of SO2 or alkane are measured. A kinetic model is proposed to fit these experimental results.The ratio of photochemical aerosol rate constant kp2 for propane,pentane and hexcane is obtained.
