【摘要】：正近年来随着我国社会经济的迅猛发展以及城市化的进程加快,空气污染也日益受到关注。以空气质量及能见度下降为特征的大气灰霾现象主要由悬浮颗粒物(particulate matter,PM)造成。PM主要由工业生产过程高温产生或是生物燃料及矿物燃料燃烧所产生,按其空气动力学直径(aerodynamical diameter,AD)可分为粗颗粒物(AD2.5μm)、细颗粒物(0.1μm≤AD≤2.5μm)和超细颗粒物(AD0.1μm)。其中
[Abstract]:In recent years, with the rapid development of China's social economy and the acceleration of the process of urbanization, Air pollution is also receiving increasing attention. Haze, characterized by reduced air quality and visibility, is mainly caused by suspended particulate matter (PMPM), which is mainly produced by high temperatures in industrial production processes or by the combustion of biofuels and fossil fuels. According to its aerodynamics diameter, AD2. 5 渭 m of coarse particles, 0. 1 渭 m of fine particles 鈮，
