中子活化分析是多元素分析。当一批样品得出结果之后,若要讨论它们之间或者它们的元素之间的亲疏关系时,仅用它们一一对应的元素含量作直接比较是难以得出结论的。而利用类聚法及其KINDTO程序,借助于一般小型计算机则可很简便、快速、形象地给出它们之间亲疏关系的图示(二维谱系图),从而便于结合它们所属的特定课题作进一步的深入研究。
Neutron activation analysis is a multi-element analysis. When a group of samples to obtain the results, to discuss the relationship between them or between elements of their relationship, only the elements of their corresponding one by one for direct comparison is difficult to draw conclusions. However, by using the clustering method and its KINDTO program, it is easy to quickly and vividly give a graphical representation of the relationship between them (two-dimensional phylogeny) with the aid of a typical small computer so as to facilitate the combination of the specific topics to which they belong Further in-depth study.
