摘　　要：用消光法 (L ight extinction)可以测量微粒的粒度及浓度 ,但一般仅限于实验室测量。本文提出一种用双波长消光法进行颗粒浓度在线监测的新方法。文中除给出理论分析外 ,还给出了实测结果。The methods to determine particle size and concentration using light extinction are well known.But usually this method can be well used in laboratory.In the paper,a new on- line method to determine particle con- centration using two- wavelengths light extinction is presented.The theoretical analysis and on- line measure- ment results are also given in the paper.The experiment results are good in agreement with off- line sampling process.
