摘要: 用放电流动-共振荧光方法(DF-RF)研究SO_2+OH+M反应。讨论了壁反应, 扩散和副反应对速率常数测定的影响, 确定该反应在298 K下氩和氮气氛中反应比速的数据分别是(1.5±0.32)×10~(-31)cm~6molec~(-2)s~(-1)和(3.6±0.79)×10~(-31)cm~6molec~(-2)s~(-1)。

Abstract: By using the method of Discharge Flow-Resonance Fluorescence, the reaction of OH+SO_2+M was studied. The effect of wall reacton, diffusion and side reaction on the rate constants of the reaction was discussed. In the atmosphere of Ar or N_2, at 298K, the measured rate constants of the reaction were (1.5+0.32) × 10~(-31) cm~6 molec~(-2) s~(-1) and (3.6±0.79)×10~(-31)cm~6 melec~(-2) s~(-1), respectively.
