| 摘 要： | 在发动机的故障诊断领域．专家系统(ES)正得到越来越广泛的应用。本首先讨论了ES的模板化思想;接着重点研究一种面向对象的规则型ES模板,包括面向对象的规则知识表示、启发性的改进DFS推理机制及图形化的人机界面三个方面;最后运用该模板创建了一个MCD磨粒诊断ES实例。应用表明,规则型ES模板化不仅增强了ES的知识表示与启发推理的能力．而且为ES的快速构造与实现开辟了一条新的途径。

| Abstract: | Expert systems (ESs) are being increasingly applied to the fault diagnosis of engines. Based on the idea of ES template (EST), an object-oriented rule-type EST is emphatically studied on such aspects as the object-oriented knowledge representation, the heuristic inference engine with an improved depth-first search (DFS) and the graphical user interface. A diagnositic ES instance for debris on magnetic chip detectors (MCDs) is then created with the EST. The spot running shows that the rule-type EST enhances the abilities of knowledge representation and heuristic inference, and breaks a new way for the rapid construction and implementation of ES. |
