摘　　要：依据《气体分析校准气体混合物的制备重量法》(1S0 6142-2001)和《气体分析气体标准样品组成的测定和校验比较法》(ISO 6143-2001),阐述了环境气体标准样品不同定值方法的量值计算及不确定度来源,并比较了同一气体标准样品采用不同定值方法得到的不同量值结果及不确定度。The calculation and uncertainty were described to compare results of an identical environmental gas reference material detected by different quantitative analytical methods according to ISO 6142＂ Gas analysis- Preparation of calibration gas mixture-Gravimetric method＂ and ISO 6143＂ Gas analysis-Comparison methods for determining and checking the composition of calibration gas mixture＂.
