库莫洛光学测量颗粒浓度方法的研究

在光学方法测量颗粒浓度时，测量的精度受颗粒粒径和颗粒颜色等因素的影响。为解决这一问题，现将颗粒的浓度、粒径和颜色三个相关联的量统一在一起进行研究，建立包含这三个属性的浑匀液体库莫洛消光散射方程。根据库莫洛前向散射消光方程可以求出受粒径影响的颗粒浓度；给出散射消光系数、吸收消光系数及有效光密度的表达式；解决Beer消光定律在实际应用中受粒径变化、颗粒浓度超限的影响。最后，用较完整的实验证明库莫洛消光散射理论是正确的。

Measurement of ParticIe Density by KML Forward Extinction Equation

The measurement of particle density is affected by particle size and color in the optical method.The Kum-belka-Munk-Lu equations were built that contained the variables of particle density,size and color.The value of particle den-sity affected by particle size could be derived by the forward scattering extinction equation of the Kumbelka-Munk-Lu equa-tions;The scattering extinction coefficient,the absorption extinction coefficient and the effective optical density equation were given.The problem was solved that the Beer extinction equation was affected by particle size and density.The experi-ments were done to test the Kumbelka-Munk-Lu equations.
