摘　　要：评定奥拉西坦注射液pH值的测量不确定度,分析奥拉西坦注射液pH值的测量不确定度的来源,建立数学模型,合成标准不确定度,给出扩展不确定度的报告。结果为奥拉西坦注射液pH值的测量不确定度为0.1,扩展不确定度为0.2,本试验测定的奥拉西坦注射液pH值结果表示为(4.6±0.2),K=2。表明本次试验的不确定度主要由修约误差和温度误差等带入。The measurement uncertainty of the pH value of Oxiraceta Injection was evaluated,the sources of measurement uncertainty of the pH value of Oxiraceta Injection were analyzed,a mathematical model was established,standard uncertainty was synthesized,and a report on expanded uncertainty was provided.The result showed that the measurement uncertainty of pH value of Oxiraceta Injection was 0.1,and the expanded uncertainty was 0.2.pH value of Oxiraceta Injection measured in this experiment was expressed as(4.6±0.2),with K=2.This indicated that the uncertainty of this experiment was mainly brought in by rounding errors and temperature errors.
