电导率加和性质及其在降水监测数据处理中的应用

采用相对电导率差（CPD）法、电导率-pH不等式法对某监测站大气降水的实测电导率和pH值等数据进行质量分析。根据分析结果认为可用CPD法来检验、评估降水中各种离子成分的分析是否完整、准确，用电导率-pH不等式法来检验电导率和pH值的测定值是否存在明显的误差。

Additivity of Conductivity and its Application in the Precipitation Monitoring Data Processing

The theory that conductivities of various ions in atmospheric precipitation could be added was the principle of conductance percent difference （CPD） method, CPD was applied to not only analyze and evaluate the monitoring data of atmospheric precipitation but also determine the accuracy and scientificity of the monitoring data. In this paper, CPD and the conductivity-pH inequality were employed for the quality analysis of the meas- ured conductivity and pH values of certain Environmental Monitoring Station, respectively. According to the re- sults, it was concluded that the CPD method could be used to test and evaluate the integrity and accuracy of the ionic composition analysis of atmospheric precipitation, the conductivity-pH inequality could be applied to test whether there is an obvious error during the determination of conductivity and pH value. Both methods were effi- cient for the accuracy and scientificity evaluation of monitoring data and also had important values for application.
