基于标准差评价测定结果的方法在环境监测领域中的应用

Application of Result Evaluation Method Based on Standard Deviation in the Field of Environment Monitoring

将基于重复性标准差和再现性标准差评价测定结果的方法应用于环境监测领域进行了探索,包括极差控制、内部精密度控制和正确度控制,并与实验室常用的质控指标(相对偏差和相对误差)进行对比,指出了这种评价方法的优点。

We applied result evaluation method based on repeatability and reproducibility standard deviation in the field of environment monitoring,including range control,internal precision control and accuracy control,made comparison with the current quality control index(relative deviation and relative error) in environment monitoring laboratory,and pointed the advantage of result evaluation method.
