稳健统计方法在煤质实验室检测能力比对中的应用
摘要
对30个煤质实验室进行能力比对试验
采用稳健统计方法统计试验结果
采用直方图对统计结果进行表述
并对煤质实验室试验结果进行评价。稳健统计方法综合考虑了试验不确定度、相对不确定度及标准偏差等因素
其结论更能真实评定实验室的检测能力。
Abstract
Through comparison of test ability among 30 coal laboratories
the results of comparison has been recorded by using the robust statistic method
and being expressed by using erect graph
and the results being evaluated.The robust statistic method considered comprehensively the uncertainty
the relative uncertainty
and the standard deviation of tests
making the conclusion to be more scientific
and can more actually evaluate the test ability of said laboratories.
