精确度可以定义为在假定相同条件下系列重复称量结果的接近度。这些结果一般表示为标准偏差。精确度经常被误解为准确度的测量;精确度与准确度有明显不同,并且这种混淆可能导致明显违反ISO有关度量衡的规定。事实是仪表或实验室之间的精确度可能很高,但是准确度由于数量级而变差。维护不善或质量低的天平可能具有较好的重复性,然而其准确度可能非常差。简 Accuracy can be defined as the proximity of a series of repeated weighing results under the same assumed conditions. These results are generally expressed as standard deviation. Accuracy is often misinterpreted as a measure of accuracy; accuracy and accuracy are significantly different, and such confusion may lead to significant violations of ISO-related weights and measures. The fact is that the accuracy between gauges or labs can be high, but the accuracy gets worse by orders of magnitude. Balances that are poorly maintained or of poor quality may have good reproducibility, however, their accuracy may be very poor. simple
