摘　　要：利用差分光谱吸收(DOAS)技术,测量大气中痕量污染气体的浓度,是当前环保行业一项热门技术。对此方法适当改进,可以用来监测工业烟道排出的SO2的浓度和排放量,研究了利用DOAS技术测量烟气的测量方法、数据处理以及减小误差的方法,实现了烟气中SO2的在线实时测量。It is a popular technology that measures SO2 concentration using Differential Optical Absorption Spectroscopy （DOAS） in environmental protecting. The SO2 concentration and its vented amount are measured based on improved method, measurement method and data processing and minishing error are studied of using DOAS, measurement of SO2 concentration from smoke is actualized on line.
