So the third chapter focuses on the measuring system. The operating principle (Lightextinctionmethod), the factors which influence the result and the resolvent to avoid them are explained.
The ultrasonic measurement results are compared with lightextinctionmethod measurement, which shows this method has a good foreground for particle sizing.
测量结果与消光法测量进行对比,表明该方法应用到颗粒粒度大小测量是切实可行的。

This paper presents a method of measuring the particle mean size and dust concentration by small angle near forward light scattering optics and the extinction theory.
