利用振動(dòng)原理實(shí)時(shí)檢測(cè)大氣顆粒物濃度的方法研究

大氣顆粒物濃度是大氣污染監(jiān)測(cè)中的一項(xiàng)重要指標(biāo)。大氣中的顆粒物，特別是PM10 及其以下顆粒物濃度的監(jiān)測(cè)一直是國(guó)內(nèi)外專家關(guān)注的問(wèn)題。提出一種實(shí)時(shí)在線測(cè)量顆粒物質(zhì)量濃度的監(jiān)測(cè)方法，該方法采用振動(dòng)原理，替代了傳統(tǒng)的離線監(jiān)測(cè)技術(shù)。經(jīng)過(guò)計(jì)算分析證明了這種方法具有可行性，并且提高了監(jiān)測(cè)工作的實(shí)時(shí)性和正確性。

Abstract：Airborne particulate matter concentration is one of key parameters in outdoor air monitoring. Monitoring of airborne particulate matter concentration has been the focus of overseas and domestic experts' attention，especially in monitoring of PM10（particulate matter generally defined as all particles equal to and less than 10 microns in aerodynamic diameter）. A method of real-time online monitoring of airborne particulate
matter concentration is proposed. It replaces traditional offline monitoring by using the principle of vibration. Computational analysis shows
that this method has the feasibility of application and improves real-time ability and accuracy.
