水泥胶砂抗压强度不确定度的分析与计算

Ascertain the Compressive Strength Uncerbainty of Cement Glue Sand

在建筑材料的检测中,检测标准只对检测的变异系数有要求,单个检测单位的变异系数只能表征偶然因素对检测结果准确度的影响,而不能使检测人员和用户确切获知检测结果和被检对象的真值之间可能的最大误差,检测结果不确定度的引入,可以解决对检测结果的准确度不能直接定量表示的难题。本文对水泥胶砂抗压强度不确定度的来源、计算和合成等进行了阐述,可以作为建材检测单位确定其他检测项目不确定度的借鉴。

In period of constract material detection,detection standard has only required about confficent of varition,singal detectional unit just display effection between accidental factor and detection outcome,but the detection personnel and the users can,t know exactly the maximum error of decteion outcome and truth ,the introducing of uncertainty of detection outcome can deal with the puzzle that the actual of detection outcome can,t be ration directly .In the article 《the compressive strength uncerbainty of cement glue sand》,there are expound about cement glue sand,scompressive strength,s source 、count、synthesize.It can be reference of detective outcome uncertainty as other constructional material institution ascertain other detection item .
