摘要
针对呼吸机潮气量不确定度评定,本文提出利用合并样本标准偏差来进行不确定度的A类评定,在较少测量次数下即可得到准确可靠的标准不确定度结果,从而达到了简化不确定度评定过程的目的。
Aiming at the measurement uncertainty evaluation of ventilator-tidal volume,proposed that the uniting standard deviation was used for type A evaluation of measurement uncertainty,Accurate and reliable uncertainty results can be obtained with fewer measurement times,thus simplifying the uncertainty evaluation process.
