| 摘 要： | 在实验室间比对Z值的基础上,利用主成分分析法,将9个参数的Z值通过降维,提取了反映综合检测能力的4个主成分,对参加比对的5个实验室加权评分,客观地评价了不同实验室综合检测能力并进行了排名,同时分析出每个主成分对应的参数.

| Abstract: | Based on the Z value of laboratory comparation,by using principal components analysis,the Z value of 9 parameter are debased dimensional,4 components which reflecting the testing capabilities are collected,5 laboratory joined are valued by plus power.Synthetical testing capabilities of differ laboratory are valued impersonality and ranked,while,corresponding parameter of the each component are analysised. |
