英文摘要：

In order to improve the accuracy and objectivity of tribology system condition identification, set pair analysis （SPA） was introduced to tribology system condition identification of sliding bearings. The basic concept of set pair analysis was used to calculate the relative value from identical-discrepancy-contrary to study the certainty and uncertainty of tribology system condition identification. Analytical hierarchy process （AHP） was used to achieve the weight of monitoring properties. The condition identification method of tribology system based on set pair analysis was established which collected the quantitative and qualitative information together, and was then used in the condition identification of sliding bearing. The results show that SPA method has the features of easy calculation and strong objectivity.
