| 中文摘要 |
| 溴代烷烃是破坏臭氧层很重要的一类物质,为了估计臭氧消耗潜势(ODP)值,利用流动放电共振荧光技术测定CH3Br和CH2Br2与OH自由基反应速率常数,计算出它们在大气中的寿命;用半经验的方法,采用最新文献报道的有关数据,计算出CH3Br和CH2Br2的ODP值分别为0.33和0.076.并与文献结果进行了比较。 |
| 英文摘要 |
| Brominated alkanes are a substances for destroying the ozone layer.In oder to estimate the ozone depletion potential(ODP),author of the paper measured rate constants for the reaction of hydroxyl radicals with CH3Br and CH2Br2 by the discharge flow resonance fluorescence technique.The lifetimes of CH3Br and CH2Br2 in tropospheric atmoshere were calculated.ODP values were calculated using semi experience method according to updated data of literature.The ODP values are 0.33 for CH3Br and 0.076 for CH2Br2.The results were compared with literature yet. |
