摘要
双样分析精密度有多种表达式。本文对标准偏差、平均偏差、极差及其应用范围作一简述。使用表达式Ｒ＝Ａ－Ｂ＜２．４８作为判据，可以简单和有效地确定常规分析中重复性精密度是否符合要求。
There exist various expressions for precision using duplicate analysis. And a brief commentary is noted for standard deviation, average deviation, and range in this paper.By using the expression R= A - B < 2. 48 as criterion, it is simple and efficient for routine analysis to determine whether the repeatibility precision is in control or not, which is in accordance with the quantitative definition for repeatibility precision in GB-3358-82.
