摘　　要：目的:用VB编程实现滴定液标定过程中不确定度的计算。方法:通过对硝酸银滴定液(0.1mol·L-1)标定过程中不确定度的计算,建立对滴定液不确定度计算的数学模型并推导出不确定度的计算公式,为VB编程奠定基础。结果:通过对各变量的分析,用VB编程计算出各变量的不确定度,最后得出扩展不确定度。结论:采用本方法建立的编程软件可用于滴定液标定过程中不确定度的计算。Objective： Determination of uncertainty of volumetric solution with Visual Basic methods through determination of the uncertainty of silver nitrate volumetric solution （0. 1 mol· L^-1 ） during the procedure of standardization, the mathematic model of uncertainty was established and the calculation formula of uncertainty was deduced from the procedure of standardization, which were the foundation of VB to determine the uncertainty. Results： Each component of uncertainty was calculated with VB by analyzing the various variable parameters in the procedure. The combined uncertainties were then finally obtained by synthesizing the uncertainties of various component variables. Conclusion ： VB can be used to determine the uncertainty of volumetric solution during the procedure of standardization.
