摘要
通过组织砂中氯离子含量检测的试验室间比对试验,采用稳健统计方法-中位值和标准化四分位距法和格拉布斯准则剔除离群值后经典统计法分析评价结果,期望达到检验各授权工地试验室试验检测的能力,提高各试验室检测人员检测水平,减少各试验室间在试验检测工作上差异性的目的。
The paper gives comparison test of the detection of chloride ion in the sand between the site laboratories.The test results of the 2 groups of sand were analyzed respectively using robust statistics of the median and norm interquartile range method,classical statistical method(outliers was eliminated),aims at promoting development of the ability of test of site laboratories,improving the testing level and quality and decreasing difference of testing between site laboratories.
