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%.
结果表明,对于大多数的牛乳样品,当其稀释倍率在6.2至7.4范围内时,测量标准偏差达到最小值0.027,满足蛋白质检测国家标准。
The result shows that measurement standard error reaches minimum 0.027 for most milk sample and satisfies the national criterion of protein detection when dilution ratio ranges from 6.2 to 7.4.
样品测量:单样品自动测量,测量次数2、3、5、10、50次任意设定,测量结束给出平均值和标准偏差。
Measurement of sample: single sample automatic measuring, measuring the number of times 2, 3, 5, 10, 50 set, measured at the end gives the average value and standard deviation.
