用米氏散射理论对光阻法微粒检测原理的诠释

A More Logical Explanation of the Light-Blockage Principle in the Particle Size Measurement

通过对微粒 光束作用的讨论,证明传统的光阻法原理仅适合于对较大粒径的粒子检测做出解释.在悬浮液透射定律的基础上,推导了对光阻法原理的另一种解释,并用Mie散射理论进行了修正,将之命名为消光原理.实验证明,消光原理是对光阻法技术的一种更加合理的解释.

Studies on the particle-beam effect have proved that the conventional explanation of the light-blockage is fit for the size measurement of relatively large particles only.On the basis of the light transmission through suspensions,another explanation of the light-blockage named extinction theory was developed and perfected according to the Mie theory.An effective experiment has validated that the extinction theory is more logical.
