摘　　要：目的:使氯化钠注射液含量测定方法受控。方法:根据JJF1059-1999计量技术规范,对滴定法测定氯化钠注射液含量的不确定度进行评定。结果:分析和量化各不确定度分量,并合成标准不确定度和扩展不确定度(K=2)。结论:滴定液的体积不确定度是主要的不确定度来源。Objective： To make the assay of sodium chloride injections under control. Method： Uncertainty for assaying sodium chloride injections by silver nitrate volumetric solution titration was evaluated according to JJF1059-1999. Result： Each component of uncertainty was analyzed and calculated, while the combined standard uncertainty and expanded uncertainty （ K = 2 ） were estimated. Conclusion： Volume uncertainty of silver nitrate volumetric solution is main uncertainty factor.
