简述了气体标准样品不确定度的来源，并对气体标准样品的不确定度进行了评定与估算。
The sources of uncertainty reference material of gases was briefly described, evaluation and statistic of uncertainty reference material of gases was also done.
结果表明，对不同氘丰度的气体样品，单次测定的相对标准偏差好于0 2 % ，氘丰度测量值在0 2 %的误差范围内是可信的。
The results indicate:relative standard deviations are better than 0.2% for gas samples of different deuterium abundance. Measure value is believable in the error range of 0.2%.
