中文摘要：

采用紫外光度法，使用美国热电子公司的TECO model49c以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64μL／m^3，变化幅度达到53μL／m^3；其频率分布呈单峰性，主要集中于55—75μL／m^3，与济南站的分散型和区域背景站Cape D’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（19μL／m^3）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．

英文摘要：

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 model49c-type UV absorption ozone analyzer manufactured by US Thermo Electron Corporation. The results show that Monthly ozone concentration is 64 μL/m^3, with a variation of 53 μL/m^3. The frequency distribution of hourly ozone concentration is one-peak, mainly in 55 - 75 μL/m^3 , obviously different from the dispersed pattern in Jinan and the two-peak pattern in Cape D＇Aguilar station, the regional background station. The ozone concentration has an obviously diurnal variation, with a variation of 19 μL/m^3 , 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.
