基于概率区间的成都市大气PM_(10)浓度的特征分析

Probability Interval-based Analysis on Atmospheric PM_(10) Concentration of Chengdu in June

以日尺度及一天内的各个时间段为基础,突破传统以PM10平均值作为衡量一个片区PM10浓度水平的做法,主张以大概率事件出现区间来判定地方的PM10浓度水平,对成都市沙河铺片区的大气PM10浓度特征进行浅析,以成都市沙河铺片区为实例,得出05:00～07:00、19:00～21:00是该地区容易出现PM10浓度值高的时段。

Based on day scale and each time period of a day,the occurrence of maximum probability events replaced the traditionally-used PM10 mean to evaluate the PM10 concentration of one district,as indicated by the analysis of the PM10 concentration in Shahepu area of Chengdu,the highest concentration of PM10 was prone to appear during 05：00-07：00 and 19：00-21：00.
