摘要
基于离子在蒸馏水中导电原理,根据各因素和电导率的线性关系,依次确定快速检测方法基准的土水比、振荡时间和温度;在此基础上做大量标定试验,建立电导率与含盐量的回归方程。研究表明:在土样烘干浸取液过滤情况下电导率与含盐量线性相关系数超过0.98,烘干未过滤两者线性相关系数超过0.97,未烘干未过滤和未烘干过滤两者间的线性相关系数也达到0.96。
Based on the conductive principle of ion in distilled water,and the linear relation between various factors and the electrical conductivity,the reference soil-water ratio,oscillation time and temperature of rapid detection method were determined in turn.On this basis,a lot of calibration tests were conducted to establish the regression equation of conductivity and salt content.The study shows that,when the sample soil is dried and the leaching liquor is filtered,the linear correlation coefficient of the conductivity and the salt content exceeds 0.98;when dried but not filtered,the coefficient exceeds 0.97;when not dried and not filtered,or not dried but filtered,the coefficient reaches 0.96 yet.
