摘要
本文运用最小二乘法、Q值比较法和逐步回归分析法,对化工厂排污海区海水砷含量分布和变化与一些理化因子的关系作了研究。研究表明,砷含量可以通过距离D、pH值和化学耗氧量COD_(Mn)三者的模拟关系式来表达。其模拟关系式为: As=144.9-1.021·InD-17.12·pH十0.1481·e~[(2·990·COD)_(Mn)]参加统计数据23组,相关系数为0.9978,剩余标准差为0.99。
In this paper, mathematical statistics, regression analysis, Q value comparison and slepwise regression analysis are used. The rule of arsenic content variation in relation .with some physical and chemical factors in an estuary that is being discharged with sewerage from a coastal chemical factory in Guangdong are studied. The study shows that the arsenic content may be modeled by a regression equation as follows.
