悬浊颗粒光学检测理论

Optical monitoring of suspension particles

在国外现有研究的基础上，从理论上推导出了悬浊液透光率脉动值的解析式。对该解析式的进一步研究表明，悬浊液透光率脉动值VR或R（R＝VR／V）主要与悬浊颗粒大小有关，颗粒个数浓度N对VR或R的影响较小，悬浊颗粒凝聚时透光率脉动值总是增大的。给出了单一粒径组成和具有一定粒径分布的悬浊液，根据其透光率脉动值计算颗粒平均粒径的解析式。

 Presents the analystic formula derived from existing overseas research for fluctuation TLFof suspension liquid turbidity and further research on this formula which comes to the conclusion that TLF value of VR or R R＝VR／V for suspension liquid is primarily related to the size of suspension particles while the concentration of number of particles has less influence on VR or R and TLF value always increases as suspension particles coagulate and gives an analystic formula for calculation of average size of particles from their TLF values which is applicable to suspension liquid with a single size of particles composition or a certain distribution of particles sizes．
