DU Yuan-hu , HUANG Wen-hu (Dept. of Aerospace Engineering and Mechanics, Harbin Institute of Technology, Harbin 150001, China)  
Discusses the representation of time factor in the knowledge base, and studies the temporal characteristics about knowledge and the temporal logic relationship of data or events and the object-oriented knowledge representation on the temporal logic by Allens theory, and points out a dynamic knowledge base can be constructed by marking and explaining real time data, then the knowledge in real time could be expressed, managed and reasoned, and the method should become a feasible and effective tool to complete the fault diagnosis in the large-scale and complex real-time diagnosis system.
