【摘要】 采用紫外光度法,使用美国热电子公司的TECO model49c型紫外吸收式臭氧分析仪,对2004年5月泰山站的地面臭氧进行监测,以获得更具华北区域代表性的臭氧春季污染特征.结果表明:2004年5月泰山站φ(O3)的月均值为64μLPm3,变化幅度达到53μLPm3;其频率分布呈单峰性,主要集中于55～75μLPm3,与济南站的分散型和区域背景站CapeD’Aguilar的双峰型分布有明显的不同;泰山φ(O3)有明显的日变化特征,变化幅度(19μLPm3)远大于中国西部的瓦里关站,这可能与泰山处于中国东部,尽管距地面较高,但不可避免地受到区域性的污染有关.更多还原

【Abstract】 In order to obtain regional variation of ozone in North China in spring , the surface ozone was monitored at Mount Tai during May ,2004 , adopting UV photometry with TECO model49c2type UV absorption ozone analyzer manufactured by US Thermo Electron Corporation. The re sults show that Monthly ozone concentration is 64μLPm3 , with a variation of 53 μLPm3 . The frequency distribution of hourly ozoneconcentration is one2peak , mainly in 55～75 μLPm3 , obviously different from the dispersed pattern in Jinan and the two2peak pattern in CapeD’Aguilar station , the regional background station. The ozone concentration has an obviously diurnal variation , with a variation of 19μ LPm3 ,which is bigger than Waliguan , a background station in the west of China. This is partly explained by the regional pollution in the east of China.更多还原
