| 中文摘要 |
| 对北京市大气中O3浓度变化规律及O3浓度变化与NOx、CO浓度变化之间的关系进行了研究。结果表明：O3浓度随温度指数上升,O3浓度和NOx、CO浓度变化之间无简单规律可寻。但在25-38℃温度范围内,O3浓度和NOx、CO浓度随温度变化趋势相反;在33-38℃温度范围内,O3浓度和NOx浓度随温度变化呈反对称。从O3浓度逐月变化分析,O3浓度变化与目前常用理论模式不符,可能的原因是大气中液态含水量对O3浓度具有一定影响。 |
| 英文摘要 |
| The variation of O3 concentration was analyzed,and relationship between O3 and NOx,CO concentration was studied in Beijing urban atmosphere.It indicated that no simply rule was found between variation of O3 concentration and variations of NOx,CO concentration.O3 concentration exponentially increased against temperature.In the range of 25 to 38℃,the variation of O3 concentration was the reverse of that of NOxand CO concentration.In the range of 33 to 38℃,the variations of O3 concentration show antisymmetric to that of NOxconcentration.Depended on monthly variation of O3 concentration,variation of O3 concentration didn't obey previous theories.It was the most possible reason that liquid water had impact on O3 concentration. |
