Three different sampling methods of dilution extraction, cold dry extraction and heat humidity extraction were compared together with five different analyzing methods including NDIR, NDUV, DOAS, UVF and CL. Results showed that cold dry extraction plus DOAS and dilution extraction plus UVF and CL are more suitable for the monitoring of ultra low emission gaseous pollutants from coal-fired power plant. %R %U http://www.hjjkyyj.com/hjjkyyj/ch/reader/view_abstract.aspx %1 JIS Version 3.0.0
