摘要
本文论证了引入模式识别技术的可能性和必要性．简单介绍了模式识别技术，重点叙述了非线性映照，主要量分析，Ｆｉｓｈｅｒ判别，聚类分析等方法的数学原理和应用特点．根据实际应用的经验，讨论了数据预处理，训练集选择，特征参数和关键参数，以及方法效果验证方法等一系列基础问题，并介绍了模式识别技术在环境腐蚀科学中的部分应用实例．
The possibility and necessity for the introduction of pattern recognition into environmental corrosion science were demonstrated.The outline of the pattern recognition was briefly introduced,and mainly,the mathematical principle and application characteristics of some popular methods,e.g.Non Linear Mapping(NLM),Principal Component Analysis(PCA),fiher discrimination method;Cluster Analysis and so on were described According to practical expenences,the important basic subjects,e.g.the data treatmentbefore the pattern recognition,he selection of learning set,the characteristic parameters and the key parameters,the checking methods of pattern recognition methods and so on were discussed.In addition,the main application fields ofpattern recognition in the environmental corrosion science was summarized.The abundant practical samples in this paper have already shown that,the powerful Interpretation ability and potentiality of these new methods will bring something new in the environmental corrosion science.
