| 中文摘要: |
| 针对2种国内广泛应用的检测银首饰中银含量的滴定方法，对其测定过程中所引入的不确定度来源进行了分析，对测定过程中的主要不确定度分量进行了量化，得到了合成标准不确定度和扩展不确定度，并对2种方法的测试结果进行了分析比较与探讨。 |
| 英文摘要: |
| The uncertainty sources for the determination procedure of two titrimetric methods widely applied in the silver component analysis of silver jewelry were analyzed, and the main component uncertainties were also quantized. The component uncertainties were synthesized and extended, and the results of two analysis methods were made comparison and discussion in this paper. |
