给水管网水质数据统计学检验模型的建立应用

Establishment and application of statistics verifying model of water quality monitoring data in networks

为了使给水管网水质分析所取数据真实、准确,应对所有实测数据进行检验、核对和识别,从而为管网水质状况的判断提供正确的依据.本文给出4种统计学检验的数学模型以及各种模型的原理和计算公式,并对其优点和缺陷作了对比.最后通过实例对管网中水质监测点的实测数据进行计算分析,判别出监测数据是否是离群,实例证明4种模型的计算结果具有客观性和科学性.

In order to obtain accurate data for water quality analysis in water supply networks, four kinds of statistics methematic verifying models were established, meanwhile their principles and formulas were introduced. Then the models were compared each other,the virtue and defect were shown as well. Experiment showed that the unwonted data in water quality analysis could be distinguished through calculation and analysis, which proves that these four models are impersonal and scientific.
