relative standard deviation

基本解释

The section standard deviations of relative errors acted as method global relative uncertainty and expanded factor was 2.
以此为依据，分段统计相对误差的标准偏差作为对应浓度段被测量结果的总相对不确定度，扩展因子为2。
The result indicated that the relative standard deviations for xylobiose's migration time and peak area were all less than 0.5%, and 2.0% respectively.
结果表明，该方法重现性好，木二糖迁移时间和峰面积的相对标准偏差分别在0.5%和2.0%以内。
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%.
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。
