电导率与溶解性总固体相关关系探讨

Correlativity of Conductivity and TDS

通过对2014—2016年某水厂泵房水电导率和溶解性总固体的相关性分析,建立了二者的一元线性回归方程:y=0.517,3x+45.253,其相关系数R=0.766 4。经过相关系数的显著性检验与方差分析,得出检验所得F值远大于临界值,因此二者具有十分显著的相关性。故溶解性总固体可由电导率通过一元线性回归方程计算得出。该方法的建立有利于快捷简便的检测水样中的溶解性总固体。

Through analyzing the correlation of water conductivity and total dissolved solids(TDS)from2014to2016in awater pump room,a unary linear regression equation was set up:y=0.517,3x+45.253and the correlation coefficient wasobtained:R=0.766,4.After the significance test of correlation coefficient and analysis of variance,the F value is provedgreater than critical value,so the two have the extremely significant correlation.The total solid solubility can be calculatedby the conductivity by monadic linear regression equation.The establishment of the method is helpful for the quick and easydetection of total solid solubility in water samples.
