钻井液滤液中氯离子含量的不确定度评定

依据测量不确定度的评价原则，从方法概述、确定不确定度的来源、建立数学模型、计算相对标准不确定度分量、合成相对标准不确定度、扩展不确定度等入手，通过实例详细阐述了钻井液滤液中氯离子含量测定的不确定度评定方法。

Evaluation on the Uncertainty of the Chlorion Content in the Drilling Filtrate

Based on the evaluation principle of measuring uncertainty,the research starts with explaining the method generally,determining the origin of uncertainty,establishing the mathematic model,calculating the uncertainty amount of relative standards,integrating the uncertainty of relative standards,and expanding the uncertainty. Then,the example is used in explaining the evaluation method of the uncertainty about the measurement of chlorion content in the drilling filtrate.
