| 摘 要： | 本文利用北京市大气自动监测系统冬季逐时SO_2、CO、NO_x资料研究城市大气污染物浓度分布的一般规律。发现:①不存在一个统一的分布模型;②对数正态分布适用于大部分SO_2和CO资料;③韦伯分布最适于高浓度的SO_2资料;④指数分布不适于城市大气污染物的浓度分布;⑤NO_x的分布较复杂。

| Abstract: | The paper deseribes three distributional models, applied to winter hou- rly sulphur dioxide carbon monoxide and oxides of nitrogen data from the Auto- matic Air Quality Monitoring System of Beljing. It was found that (a) exist no "universal" distribution,(b)lognormal distribution is appropriate for the majority of sulphur dioxide and carbon monoxide data sets, (c) Weibull distribution is best for highly sulpher dioxide data, (d) exponential distribution is not appropr- iate for urban air pollution data sets, (e) the distribution for oxides of nitrogen is different with location. |
