Because mtl algebras are a kind of basic algebra systems , these results are true in other algebra systems such as r0 algebras , mv algebras , bl algebras and wnm algebras finally , the paper proves that two archimedean t - norms are isomophic when their corresponding decreasing generators have certain relation , this work enables us to easily judge if two archimedean are isomophic . this simplifies hajek ' s work to a great extent 第四章：证明了当两个阿基米德卜范的减生成子具有某种关系时，这两个阿基米德t范是同构的；这个工作使得仅需判断两个阿基米德t范的减生成子在0处的值，便可以搞清楚它们是否同构，这在很大程度上简化了hdjek的工作
