空气中臭氧变化特征分析

利用空气自动监测子站中O3自动监测分析仪，对2007年2月－2008年2月鞍山深沟寺地区进行24小时连续监测，利用连续监测的数据，研究了空气中臭氧全年总体分布、季节变化、日变化规律。结果表明，本地区φ（O3）全年平均值为0．068mg／m^3，φ（O3）月均值在春末夏初季节出现达到最大值，在11月一次年1月出现低值，说明鞍山地区夏季臭氧光化学反应比较强烈。φ（O3）浓度随季节变化明显，春末夏初随日照时间加长而增高，最大月均值和最大日均值均出现在此时期，冬季随日照时间的减短而降低。

Analysis of Variation Features of Ozone in the Air

Using O3 automatic monitoring analyzer,24-hour continuous monitoring was carried out from February 2007 to February 2008 in Shengousi District of Anshan.Based on obtained data,general distribution of ozone in the air and its regularities of seasonal variation and daily variation were studied.The results showed that yearly mean value of O3 was 0.068 mg/m3,monthly mean value reached maximum in the end of spring and the beginning of summer,and the lowest value appeared between November and the following Januar...
