关联度分析在排放特性检测中的应用

基于在用车的排放因子具有灰色特征，利用相似视角下的灰色关联度分析方法，对在VMSA排放检测平台上做出的排放特性检测结果进行分析研究，比较其关联度大小，并对排放特检测结果的可信性和重复性做出判定。结果显示，检测结果的重复性高、是可信的。该方法能够快速准确地对检测结果作出判断，与其他研究方法得出的结果一致，是一种科学、实用的方法。

Correlation Analysis in the Detection of Emission Characteristics

To ensure accurate and reliable detection results in detecting in-use vehicle emission characteristics, the grey correlation analysis from similar perspective was used to analyze the credibility and repeatability of the result of in-use vehicle emission characteristics from VMSA emission test platform, and feasibility of the method was verified. Studies have shown that this method is a scientific and practical one in that it can make rapid and accurate judgment about results of the test in consistence with studies or tests otherwise.
