【摘要】 使用单颗粒气溶胶质谱仪(SPAMS)分析了淮安市冬季大气中单颗粒PM2.5的特征。对采集到的颗粒物利用MATLAB进行处理,解析得到机动车尾气、燃煤、工业工艺源等7大颗粒物来源。初步判断,灰霾污染发生很可能是由于扩散条件不利致使燃煤及机动车尾气源累积,二次转化加剧而导致。更多还原

【Abstract】 Using single particle aerosol mass spectrometer( SPAMS),the characteristics of the single particles PM2. 5particles in winter atmosphere in huaian City were collected for using MATLAB for processing. Motor vehicle tail gas,coal,industrial technology and so on,seven key source of particulate matter were parsed. Through preliminary judgment,the ash haze pollution is likely to be resulted from the diffusion adverse conditions,causing coal source and motor vehicle tail gas accumulation,and quadratic transformation.更多还原
