摘要
建立了量化因果图的概念及方法,以CCQM P111为例进行分析和表述。研究表明,量化因果图可以在因果图定性分析基础上,进一步对主要影响因素的不确定度贡献分量表述,具有清晰、直观的特点。该方法可以应用在化学计量不确定度评定及类似领域。
Concept and method of Quantitative-characteristic diagram figure were established and applied in the study of CCQM P111.It proved that the method can describe the amount of uncertainty for major factors in quantity on the basis of reason-result figure in quality.Inaddition,the method could be applied in estimation of uncertainty in chemical uncertainty assessment and similar studies simply and dearly.
