摘要
本文利用2004-1-1至2004-12-31共12个月的臭氧自动连续监测数据,对三明十中O3浓度的频率分布、日变化、月变化等特征进行分析并提出控制措施。实验结果表明,O3小时平均浓度达到《环境空气质量标准》(GB3095—1996)一级标准的频率为96.30%;O3浓度呈明显的日变化,一般在下午浓度较高,上午和夜晚较低;O3浓度的最高值出现在8月份,这与辐射强度大,温度高有关;天气条件也影响O3浓度,一般晴天时O3浓度高,多云、阴雨天气O3浓度低。
The temporal distribution characteristics of ozone concentrate are analyzed based on automatically successive monitoring data at the tenth middle school ,Sanming monitoring station. The control measures are put forward as well. The resuits indicate：①6.30 percent of hourly average ozone concentrate fit grade I standard value in 《 Environmental Air Quality Standard》 ;②The daily variation of ozone concentrate is significant. It is higher in the afternoon and lower in the morning and evening. ③The ozone concentrate apex makes it, s presence in April, which is related to the stronger radiation and higher temperature; ④ Ozone concentrate is also affected by weather conditions. Generally, it increases in fine days and drops in cloudy days and rainy days.
