摘　　要：应用场发射扫描电镜(FESEM)分析了2020年8月至2021年1月新余市PM_(2.5)的微观形貌及其元素组成特征.结果表明,新余市PM_(2.5)具有微观颗粒物类型10种,主要为碳质颗粒物、燃煤飞灰颗粒、铁铜锌氧化物颗粒、扬尘颗粒等。不同季节微观颗粒物占比差异较大。Characteristics of micromorphology and element composition of PM_(2.5)in Xinyu collected from August 2020 to January 2021 were investigated with field emission scanning electron microscopy(FESEM).The results showed that ten main types of microparticles were identified including carbonaceous particles,coal fired fly ash particles,dust particles,iron copper zinc oxide particles,etc.The proportion of microparticles varied greatly in different seasons.
