| 摘要: |
| 利用有机元素分析仪，对氮掺杂二氧化钛中氮元素的含量进行了测定，评定了其测量不确定度。分析了测定过程中的不确定度的来源，并对不确定度的各个分量进行了评定，给出了测定结果的合成不确定度和扩展不确定度。结果表明：不确定度可表示为（1.21±0.16）%，k=2，其中校准曲线对不确定度的影响最大。 |

| Abstract: |
| The nitrogen in nitrogen-doped titanium dioxide bacterial agent was detected by elemental analyzer,and the measurement uncertainty was evaluated.The sources of uncertainty among the procedures were analyzed and each component of uncertainties was evaluated.The combined and expanded uncertainties were given.The results showed that the uncertainty can be expressed as(1.21±0.16)%, k=2, and the calibration curve has the greatest influence on the uncertainty. |
