| Abstract: | In studying the Fault Diagnosis Expert System of a certain type of air separation system,the conception of Binary Fault Tree(BFT) is proposed for fault tree analysis.On the basis of one of fault phenomenon of turbo-expander,the BFT is built.On the basis of the BFT,the stress is put on the computer presentation of BFT and the mechanism of diagnosis and reasoning in this paper. |
