| 中文摘要 |
| 利用长光路FTIR测定甲苯、三甲苯等芳香烃化合物在烟雾箱中光化学反应衰减,确定了NOx-H2O-Air、HONO-H2O-Air和CH3ONO-NO-Air 3种体系在黑光灯照射下的OH 浓度,结果表明三者OH浓度范围分别为:～105～106、～107、～107～108molecules·cm-3,并进一步讨论了反应前体物对生成OH 浓度的影响。 |
| 英文摘要 |
| The concentration of hydroxyl radical in three different OH generating systems was measured from the decay of some aromatic hydrocarbons such as toluene and mesitylene using long path FTIR.These three systems were NOx-H2O-Air,HONO-H2O-Air and CH3ONO-NO-Air,irradiated by four black lamps.Under the experimental conditions employed,the ranges of OH concentration were～105～106,～107 and～107～108molecules·cm-3,respectively.The factors influencing the concentration of the generated OH were discussed. |
