摘要
论述了乙烯中一氧化碳、二氧化碳和乙炔混合气体标准物质的制备方法、性能考察、不确定度计算,经与国内同类标准物质比较,证明量值准确可靠、方法可行。
It introduces the method of preparation, research of performance and calculation of uncertainty of mixed gas reference material of carbon monoxide, carbon dioxide and ethyne in ethylene. It is proved that the magnitude of the reference material is accurate and the method of preparation is feasible after compared with similar reference material from home.
