摘　　要：本文提出了一种新的模糊模式识别方法。这种方法第一步是从已有的物理现象中，提取出支持不同类物理机制的“证据”。证据的提取采用了文中提出的模糊数学方法。第二步是去比较支持不同物理机制的证据，最后一步是给出模糊模式识别结果。本文把证据论和模糊数学成功地结合起来，建立新的模糊识别方法。显然，新方法可望在广泛的领域中得到应用，最后，本文用所提方法研究了炉霍地震（１９７３，Ｍｓ＝７．９）的破裂机制。In this paper,a kind of fuzzy identification method is proposed.The first step of the method is to ) Abstract several kinds of evidence,which support different kinds of physical mechanism,from the existed physical phenomenon and the existed data.The evidence is ) Abstract ed by means of a kind of fuzzy mathematics method ,which is proposed here.The second step is to compare different kinds of evidence,which support different kinds of pretended physical mechanism.The last step is to give the results of identification.In this paper,both the theory of evidence and the fuzzy mathematics are used together successfully in building the new fuzzy identification method.Obviously,the new method proposed here can be used in the widely fields.At last,the earthquake rupture mechanism of LuHuo(1973,M s=7.9) earthquake is studied by means of this method.
