摘　　要：文章通过对膨润土pH值测定的不确定度进行分析,建立不确定度的数学模型,找出不确定度的来源,并对各个分量进行分析,评定了合成标准不确定度,为膨润土性能指标测定提供了依据和参考。Through the analysis and evaluation of the uncertainty of the pH value determination of bentonite,the mathematical model of uncertainty is established,the source of uncertainty is found,and the various components are analyzed,and the uncertainty of the synthetic standard is evaluated,which provides the basis and reference for the measurement of bentonite performance index.

关 键 词：膨润土 PH值 不确定度
