Abstract：We have expanded the limitations of classic pattern recognition and expert systemmethods in refrences〔1〕and〔2〕,respectively,and presented the idea of the combina-tion of the two to realize pattern recognition expert system,and given a thinkingmodel of incomplete-reasoning and regressing which is used to realize the above idca.This paper presents a pattern recognition system based on feature and knowlcdge,i.e.,on a background of analysis of rock properties of earthquake section image,andrealizcd by using the above thought model.And some theoretical and practicalproblems of this method are discussed in detail.An application example is given.
