摘要
以西藏饮用天然水为例,溶解性总固体依据《饮用天然矿泉水检验方法》(GB 8538-2016)的测定值比《生活饮用水标准检验方法》(GB/T 5750-2006)高约15.1%。通过SPSS统计分析软件对溶解性总固体与电导率进行相关和回归分析,结果显示:溶解性总固体(生活饮用水、天然矿泉水)与电导率的皮尔逊相关系数分别为0.978和0.983,具有极强的正相关性,两者间线性关系显著,比值分别约为0.65和0.86。
Taking Tibet drinking natural water as an example,the determination results of total dissolved solids according to Examination method for drinking natural mineral water(GB 8538-2016)was about 15.1%higher than that of Standard examination method for drinking water(GB/T 5750-2006).The correlation analysis and regression analysis between total dissolved solids and conductivity were carried out by SPSS statistical analysis software.The results showed that the Pearson correlation coefficients between the total dissolved solids(drinking water and natural mineral water)and the conductivity were 0.978 and 0.983,respectively,which had a very strong positive correlation.The linear relationship between the two variables was significant,and the ratios were approximately 0.65 and 0.86,respectively.
