摘要：

Emission from laser-produced C2 has been studied at different heights in premixed ethyleneoxygennitrogen flames at various fuel-oxidant ratios and laser pulse energies for the wavelengths 266, 355, and 532 nm. At the laser wavelengths 355 and 532 nm, the laser-produced C2 emission was detected in sooting flames, both in the sootfree reaction zone and in the sooty region, whereas using 266 nm radiation it was observed both in sooting and nonsooting flames. Polyaromatic hydrocarbons were monitored by laser-induced fluorescence and the properties of the soot particles were determined using scattering/extinction measurements. © 1990.
