铀标准溶液不确定度分析

摘要：分析了由八氧化三铀配置标准溶液过程中有关参数信息。如天平、吸量管、容量瓶、滴定管等因素对铀标准溶液测量不确定度的影响，这些因素反映了测量系统不确定性的基本特征，实际上是误差源引起的测量系统不确定度的主要原因，考虑误差源对合适指标特征的不确定度评定，计算出铀标准溶液合成不确定度与扩展不确定度结果为{ 0.44% }。铀标准溶液测量结果表示为（25.29±0.44）Bq/mL

Indeterminacy Analyse of the Uranium Standard Solution

Summary: Have analysed relevant from eight oxide three uraniums allocation standards solution process middle parameter information. If balance, attracts impacts of factor over uranium standard solution measurement indeterminacy such as burette , capacities bottles , buret, these factors have reflected measurement system uncertainty essential features , the main cause being the measurement system indeterminacy that the error source arouses in fact, has thought that the error source indeterminacy to right index characteristic appraises , the solution calculating out the uranium standard composes indeterminacy and the result expanding indeterminacy is {0.44% }. Solution measurement result expresses the uranium standard for (25.29 +/-0.44) Bq/mL
