基于格拉布斯检验法测定铅锌矿中的铜元素
|
摘要
铅锌矿是一类含有大量金属元素的矿产,大多为铜、铁、锌、镉、银等元素,准确地测定其中的含量是为了更好地利用其工业价值。检测中会产生大量的统计数据,为了判断测量结果的准确性,并有效剔除结果中出现的离群值,需要考虑异常值的判别与剔除。本文采用格拉布斯检验法对铅锌矿中铜元素含量测定的异常数据进行了分析,该法具有准确性高、可靠性好的优点。
Lead-zinc ore is a kind of mineral containing a large number of metal elements, most of them are copper, iron, zinc, cadmium, silver and other elements. The accurate determination of the content of lead-zinc ore is to make better use of its industrial value. In order to judge the accuracy of measurement results and effectively eliminate outliers in the results, it is necessary to consider the discrimination and elimination of outliers. In this paper, Grabbs test is used to analyze the abnormal data of the determination of copper content in lead-zinc ore, which has the advantages of good accuracy and high reliability.
