1.相似元的概念 系统通常是由多个相互作用要素组成具有一定结构与功能的有机整体。其中每一组成要素具有一定属性和特征,而任一系统内部要素的特性必有其外部表现形式。人们在对两个或两个以上不同系统中存在要素特性的比较过程中,对于某些具有相同属性和特征的同类要素,其特性往往在数值上存在差异,即特性相似,把它的外部表现形式认识为相似现象。

Each of these elements has certain attributes and characteristics, and the features of any system’s internal elements must have their own external manifestations. In comparing two or more different system features, the characteristics of the same kind of elements with the same attributes and characteristics tend to be numerically different, that is, the characteristics are similar, and its external representation Formal recognition is a similar phenomenon.
