先根据龟板及其混伪品紫外光谱峰位波长点赋值，然后对此量化矩阵用电脑求得相似矩阵，再进行聚类分析。结果表明：该法既可用于科属种分类，又可作品种鉴定，而且均表现出客观的量化概念 First, according to the value of the peak wavelength of the ultraviolet spectrum of the turtle shell and its counterfeit products, the similarity matrix is ​​then calculated by a computer using this quantization matrix, and then the cluster analysis is performed. The results show that this method can be used not only for the taxonomic classification of species, but also for the identification of works, and they all exhibit an objective quantitative concept.
