转基因产品标准物质定值系统设计与应用

Design and Implementation of Certified Reference Material Value Characterization System for Genetically Modified Organisms

针对转基因产品标准物质定值对象复杂、流程繁琐、效率低下、准确度低的现状,设计并实现集数据抽取、数据分类、数据筛选与定值为一体的转基因产品标准物质定值系统。通过分析转基因生物标准物质的表现形式并对其分类,解决对象的复杂性问题;采用精密性检验、正态性检验、组内可疑值检验、组间平均值检验4个环节进行数据筛选,优化工作流程,提高定值效率;在此基础上,对筛选出的数据进行定值分析,最终提高了转基因产品标准物质的定值效率与准确度。试验证明,该系统能够满足实际应用的需求。

In light of the current value characterization of certified reference material with complex objects, complicated process, inefficient and low accuracy for genetically modified organisms, a certified reference material value characterization system for genetically modified organisms was designed and implemented, which integrated data extraction, data classification, data filters and value characterization as an entirety. The object complexity was solved through the analysis of genetically modified organismscertified reference material5 s manifestations and classification ; the data filters were done using precision test, normality test, suspicious test within group and average test between groups, so as to optimizeworkflow and improve efficiency. On this basis, the selected data were analyzed and valued, finallyimproving the efficiency and accuracy of value characterization. The experimental illustrated that thissystem could meet the demand of practical application.
