地质学中有大量定性的或半定量的资料,不能用确切的数字进行描述,对于这种非数值的地质资料的研究往往只是根据经验的比较,不同的研究者对同一范畴的地质现象,因为经验的不同可以得出完全不同的结论。在通往数字化的道路上,二态(有—无)聚类分析是较早引入处理非数值的地质资料的方法之一,现在这方法已广泛应用于地质资料的研究,并取 There are a large number of qualitative or semi-quantitative data in geology, which can not be described by exact numbers. The research on this non-numerical geological data is often based on empirical comparison. Different researchers have the same category of geological phenomena because Different experiences can lead to completely different conclusions. On the way to digitization, the binary state (yes-no) clustering analysis is one of the methods introduced earlier to deal with non-numerical geological data. Now this method has been widely used in the study of geological data, and take
