微粒的运动随机性对其光散射频谱的影响

The affection to the scatting spectrum of small particles by it's moving

本文针对提高粒度仪的精度问题 ,从理论上较系统地研究了真实情况下被测微粒的动态随机性 (高斯光敏区内微粒速度分布、跟随性、位置分布、空间取向等动态随机性 )对Mie散射光谱的破坏作用 ,从而指出这种作用是目前影响粒度仪精度提高的主要原因。

The scatting characteristics of the moving particles in real case is researched for it's measuring precision.It is found that the velocity,following and delaying of the particle will affect the Mie scatting spectrum of its,so the measuring errors will be produced.That is the key cause affecting the precision of the machine.
