目的：加深对测量不确定度概念的理解和实际操作过程的掌握。方法：对测量不确定度的基本概念及重要性作以介绍，按照JJG270-2008《血压计和血压表计量检定规程》对汞柱式血压计测量结果的不确定度进行评定，从而获得被检血压计的示值误差。结果：被检血压计的示值误差表示为：=0.2 kPa±0.4 kPa，νef =40，k =2.02。结论：在血压计检定过程中，测量结果的不确定度大小取决于测量过程中存在的误差。
目的：加深對測量不確定度概唸的理解和實際操作過程的掌握。方法：對測量不確定度的基本概唸及重要性作以介紹，按照JJG270-2008《血壓計和血壓錶計量檢定規程》對汞柱式血壓計測量結果的不確定度進行評定，從而穫得被檢血壓計的示值誤差。結果：被檢血壓計的示值誤差錶示為：=0.2 kPa±0.4 kPa，νef =40，k =2.02。結論：在血壓計檢定過程中，測量結果的不確定度大小取決于測量過程中存在的誤差。

Objection: To further understand the concept of uncertainty in measurement and grasp the process of actual manipulation. Method:The basic concepts and importance of uncertainty in measurement were introduced in this paper, uncertainty in measurement of mercury sphygmomanometer was evaluated according to JJG270-2008 Verification Regulation of Mercury Sphygmomanometer, thus error of indication of the verified mercury sphygmomanometer was achieved. Results: The error of indication of of the verified mercury sphygmomanometers was expressed as= 0.2 kPa±0.4 kPa, νeff = 40, k =2.02. Conclusion: During the verification of mercury sphygmomanometer, uncertainty in measurement was mostly decided by the existing errors in measurements.
