摘　　要：提出了能直接测量烟尘和粉尘排放浓度和粒径大小的激光监测技术 ,具有实时快速、非接触、在线、无需取样和连续测量的优点。实验研究表明了该项技术的工作原理是正确的 。A laser based technique is proposed which is able to measure and supervise the mass concentration and particle size of smoke and dust in emissions. It is characterized by fast, non-contact, on-line and continuous measurements and gives a direct results of mass concentration in mg/m3. Experimental studies proved that the proposed method is correct in principle and accurate in the measurements.
