论文摘要
除一（1）外，通过有序的一对元素为每个自然数字提供了一个表征。第一个元素是一个自然数字，称为自然数字的类型，第二个是自然数字，称为自然数字，称为其类型中的数字的顺序。在二进制树的集合之间指定一对一的对应关系，以便a）给定节点没有子节点（即，它是终端节点），或b）它具有两个子节点。因此，二进制树使他们的父节点之一只有一个子节点被排除在此处考虑的集合中。
A characterization is provided for each natural number except one (1) by means of an ordered pair of elements. The first element is a natural number called the type of the natural number characterized, and the second is a natural number called the order of the number characterized within those of its type. A one-to-one correspondence is specified between the set of binary trees such that a) a given node has no child nodes (that is, it is a terminal node), or b) it has exactly two child nodes. Thus, binary trees such that one of their parent nodes has only one child node are excluded from the set considered here.
