| 摘要: |
| 为建立紫外分光光度法测定维生素B1注射液含量的不确定度评价方法，利用数学模型分析溶液配置过程和仪器测定过程的不确定度来源，并对各分量进行评价，最后计算了扩展不确定度并给出测量不确定度报告。维生素B1注射液含量测定结果可表示为（93.9±0.9）%（k=2）。测量结果不确定度的主要来源为紫外分光光度计和小容量量器。 |

| Abstract: |
| Establish a method for evaluate the uncertainty of determination the content of vitamin B1 injection by UV method. A mathematical model of uncertainty of Vitamin B1 injection was established and the uncertainty of each variable was calculated, at last calculated the expanded uncertainty and showed the report of uncertainty of determination. The result of content determination can be expressed as (93.9±0.9)% (k=2)．The main sources of measurement uncertainty were ultraviolet spectrophotometry and small capacity measuring vessel. |
| Key words: uncertainty vitamin B1injection ultraviolet spectrophotometry |
