| 摘 要： | 分析了北京市石景山区秋季PM10质量浓度的变化特征，发现气候变化对PM10质量浓度有很大影响。利用带能谱的扫描电镜（SEM／EDX）分析了PM10的微观形貌特征，区分出矿物颗粒、燃煤飞灰、烟尘集合体、超细颗粒物和未知颗粒物等五种成分，并对所采样品中的矿物颗粒成分进行了分析。石景山区PM10污染呈燃煤污染、机动车尾气污染和扬尘污染的复合污染特征。

| Abstract: | This paper analyses the change of PM_(10) mass concentration at Shijingshan District in autumn,and finds that climate change affects PM_(10) mass concentration greatly.PM_(10) microscopic characteristics have been analyzed by Scanning Electron Microscopy/Energy Dispersive X-Ray(SEM/EDX),and revealed five main types of particles: mineral particles,coal fly ashes,soot aggregates,ultrafine particles and unidentified particles.At the same time, the components of mineral particles have been analyzed by EDX.PM_(1... |
