医用气体流量计量检定标准装置的研制与不确定度分析

Research of Metrology Standard Unit for Medical－gas Volume Flow and Uncertainty analysis

在研制医用气体流量测量仪（系列）的基础上，又研制了一套医用气体流量2级计量标准装置。为建立医用氧气及其它气体流量计的计量标准作了一些探索，并简述了该装置的结构、原理及其不确定度分析。

In the research of series of apparatus for mecical gas volume flow, a set of 2nd degree metrology standard unit for medical gas volume flow is also developed. Some research for setting up the measurement standard of oxygen and other gas volume flow meter for hospital are get. The structure, the method and the uncertainty analysis of this unit are simply discusses.
