摘要
应用数据挖掘法对3 720台次汽油车的BASM排放检测数据进行关联性分析,对汽车BASM排放检测方法中检测工况及排放污染物检测项目CO、HC、NOx间关联性进行研究,得出在BASM 5024工况下没有通过检测的车辆在BASM 2540工况检测的通过率只有5.7%,CO检测合格对HC的检测合格有76.5%的支持度,HC检测合格对NOx检测合格的支持度为58.9%,说明BASM 5024与BASM 2540检测工况具有较高的关联性,HC与CO存在较高的关联度,而HC与NOx的关联度不高。
The association rule of BASM exhaust emission inspection method was studied. It was analyzed 3 720 groups of data about gasoline vehicle exhaust emission under BASM test by the way of data mining. The results indicated that there were only about 5.7% vehicles which could passed BASM 2540 test if the vehicles did not passed BASM 5024 test. The support was 76.5% between the confirmation of CO and HC, and 58.9% between HC and NOx. It came to conclusions that there was high association between BASM 5024 test and BASM 2540 test, CO and HC, but HC and NOx not.
