| 摘 要： | 叙述了小尺寸流量管的校准方法和不确定度评定方法,分析了采用对比标定法校准小尺寸流量管流量系数的原因,并给出了某流量管校准试验结果和不确定度评定结果.结果表明,即使标准节流装置的测量精度不满足标准要求,但只要其不确定度已知,仍可用于其它流量装置的校准,而且可评定被校流量测量装置的不确定度.

| Abstract: | An evaluation method on calibration and measurement uncertainty of an airflow rate measuring tube was introduced.It gave the reason for utilizing comparison calibration method to calibrate the flow coefficient of a small scale airflow tube.The calibration results and measurement uncertainty of a measuring tube are obtained.The results showed that even if the precision wasn't high enough,with known uncertainty,standard orifice unit was still used to calibrate other airflow measurement units,whose measurement... |
