摘　　要：建立了三磷酸腺苷(ATP)溶液标准物质不确定度评定模型,分别从该标准物质的均匀性、稳定性、定值过程3个方面进行不确定度评定,其中着重探讨了定值过程中各测量影响因素引入的不确定度分量,分析了影响标准物质量值结果的不确定度的主要来源。ATP溶液标准物质的量值检测结果为1.000×10-4mol/L,其扩展不确定度为0.074×10-4mol/L;不确定度的主要来源是稀释配制工作标准溶液产生的不确定度。The assessment model was established to evaluate the uncertainty in the development of ATP solution reference materi- al. The uncertainty caused by inhomogeneity,instability and deviation in the quantification procedure was fully evaluated,and the uncertainty from the measuring influence factors was discussed especially. Finally, the concentration of ATP solution reference ma- terial is 1. 000 × 10^ -4 mol/L, and the expanded uncertainty is 0. 074×10^-4 mol/L （ k = 2 ）. The main source of the uncertainty was the dilution of the working standard solutions.
