The ultrasonic measurement results are compared with light extinctionmethod 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。

So the third chapter focuses on the measuring system. The operating principle (Light extinctionmethod), the factors which influence the result and the resolvent to avoid them are explained.
