常规控制图用于室内环境检测实验室测试过程受控判定方法的探讨

Applying Shewhart Control Chart As the Determining Method of the Controlled Testing Procedure of Indoor Environment Inspection Laboratory

利用统计学原理,收集测试过程稳定状态下的质控样标准物质浓度数据,制作质控样标准物质的常规控制图,用于室内环境检测实验室测试过程受控判定,方法可行。

Based on the principles of statistics, concentration degree data of the standard material of quality con- trol sample are collected under stable state in the course of testing.The data collected are used to draw Shewhart Control Chart of the standard material of quality control sample, and the chart is used for determining controlled testing procedure of indoor environment inspection laboratoryl The method is feasible.
