锌滴定液标定的不确定度评定

Evaluation of Uncertainty for Calibration of Zinc Standard Solution

目的建立锌滴定液（0．05mol／L）标定结果的不确定度评定方法。方法建立数学模型，对标定过程中各种影响因素进行分析评估。结果通过计算各变量的不确定度，计算出合成标准不确定度和扩展不确定度。结论采用本方法建立的数学模型可用于滴定液标定过程中不确定度的评定。

Objective To evalute uncertainty for calibration of Zinc standard solution （0.05mol/L）. Methods Establishing a methematical model to evaluate the factors affecting sample detection. Results Each component of uncertainty was calculated by analyzing the various variable parameters among the procedures .The combined uncertainty was then finally obtained by synthesizing the uncertainties of various components.Conclusion Use this method establishment the mathematical model to be possible to use in the standard solution demarcation process the uncertainty appraisal.
