| 摘 要： | 烟尘及各种工业性粉尘排放是典型的气-固两相系．迄今为止，国内外尚缺少有效的监测其排放的手段．本文基于光的散时原理，提出了一种非接触的光学方法，能对上述固体颗粒物的污染排放浓度及粒径大小进行实时、在线的监测。计算机模拟和实验研究表明，该方法具有广阔的工业应用前景。

| Abstract: | Up to now effective technologies and methods used to monite and supervise the parti-clulate industrial exhausts are scarce. Based upon the laser scattering theory, a new non-intrusive optical method is presented, which can be used to perform real-time and on-linemeasurements of mass concentration and particle size of the exhausts. Numerical calcula-tions as well as experimental studies show that the presented method has a wide prospect inthe industrial applications. |
