| 摘 要： | 介绍了紫外法测量水质COD的测量原理，并且论述了温度在其测量中的影响。为消除温度对测量数据的影响，通过实验测定了三种浓度的COD水样对紫外线的吸光度随温度的变化数据，利用多元线性回归的方法对所测数据进行处理，从而得出了吸光度和温度之间的关系，为消除温度影响提供了依据。

| Abstract: | Introduce the theory of measuring COD in water with UV technique and discuss temperature influence in this measurement.In order to eliminate the influence of temperature in the water COD measurement,measure the absorbency data of three different COD consistencies water under different temperature by experiment.Use multiple linear recursive equation to deal with the data,get the relation between absorbency and temperature,offer foundation for eliminating temperature influence. |

| Keywords: | temperature absorbency ultraviolet(UV) chemical oxygen demand(COD) |
