light extinction method的意思|示意

The ultrasonic measurement results are compared with light extinction method 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 extinction method), the factors which influence the result and the resolvent to avoid them are explained.

第三章对此磁致偏振特性测量系统的搭建及工作原理（消光法）、影响测量结果的因素及解决方法、实验操作步骤等作了说明。

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.

本文综合前向小角光散理论及消光原理，提出一种测量粉尘平均粒径及粉尘浓度的光学方法。
