单项形变、应变资料信息的提取方法

METHODS TO EXTRACT INFORMATION FROM MONO-DEFORMATION-STRAIN DATA

介绍了4种单项形变、应变资料信息提取方法，即多点组信息法、信息标准化方法、畸形参数法和信息丛集度法。按定义，μ值法亦可归属多点组法，故对μ值法亦作了介绍。这些方法提取出了新的信息，具有不同的新特点和应用范围，在实际应用中均初步取得了较好的效果。

In this paper, some methods to extract information from mono-deformation-strain dataare presented. They are multipoint-group method, information normalization method, irregu-lar parameter method and information clustering method. According to the definition, μ valuemethod also belongs to multipoint-group information method,so μ value method is present-ed,too. These methods all have new contents,and some new in formation can be extracted bythem. Meanwhile,they have different characteristics and new applied areas.
