摘要:

以能量计量为实例，提出了建立天然气分析测试溯源性准则的基本原理，后者与国际标准ISO14111：1996的规定是一致的。建议通过室间试验和实验室——现场比对试验，进一步判明气相色谱法分析天然气组成（GB／T13610-2003）的精密度；并通过与直接燃烧（热量计）法的比对确认测定结果的准确度。

Abstract:

The traceability for natural gas analysis and measurement, in essence, is that of reference gas mixture. Although China has not issued national standard of traceable guidelines for natural gas industry, practical operations are in keeping with the rules l
