摘要
提出平行双样精密度控制图和加标回收率准确度控制图的绘制和使用方法,既可用于个人自控,又可用于实验他控,简便易行,且能打破质控样浓度单一的局限性。
This article proposes the drawing and applying method of the parallel precision control print and the marked return rate precision control print.This simple and applicable method can be used for individual control or in the lab and break the limit of monotonous desity of the quality control sample,meeting the quality control needs of samlles of different density.
