在智能故障诊断中, C(C++)语言具有多方面优于传统人工智能语言(如LISP、PROLOG)的特性, 它对递归的支持使得用

其来开发故障诊断专家系统成为可能。本文研究了故障诊断专家系统开发中用到的递归方法及其基于C(C++)的实现, 具体

包括: 动态数据库设计中结构体的递归定义, 推理机设计中函数的递归调用等。针对知识推理中易出现的“循环递归”问题,

提出了一种基于“因果网络直观图”的解决方法。-C ( C++ )language possesses characteristics which are superior to traditional artificial intelligent languages (such as LISP 、

PROLOG) in the intelligent diagnosis, and it is possible to develop expert systems (ES) with its support to recursion. The paper studied

the recursive method used in ES and the key technologies with C (C++) in the construction of fault diagnosis ES, which included

the recursive definition of the dynamic data base structure and recursive function in the design of inference engine. In order to solve

the ‘cyclic recursion’problem which frequently appears in ES, an effective solution based on causal network model was proposed.
