【摘要】：正近年來隨著我國社會經(jīng)濟的迅猛發(fā)展以及城市化的進程加快,空氣污染也日益受到關(guān)注。以空氣質(zhì)量及能見度下降為特征的大氣灰霾現(xiàn)象主要由懸浮顆粒物(particulate matter,PM)造成。PM主要由工業(yè)生產(chǎn)過程高溫產(chǎn)生或是生物燃料及礦物燃料燃燒所產(chǎn)生,按其空氣動力學(xué)直徑(aerodynamical diameter,AD)可分為粗顆粒物(AD2.5μm)、細顆粒物(0.1μm≤AD≤2.5μm)和超細顆粒物(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，
