浊度测量原理的探讨

摘要

Firstly,the concept,the significance and the unit of turbidity are introduced in this paper. Then,the theoretical basis of scattering method,transmission method,and ratio method is analyzed in detail .And,the paper formulates the relation between the measuring signal and the turbidity.Finally,this paper analyzes the characteristics of the three methods and points out characteristics and applications of the four types of scattering method.%　　介绍了浊度的概念，浊度测量的意义及浊度各种单位。分析了散射法、透射法及散射与透射比值法三种测量原理的理论依据，给出了测量信号与浊度的关系式。对三种测量原理的特点进行了分析，并指出了散射法四种应用方式的不同特点及场合。
