基轮换与一般的一一变换

The Basic Rotation or General One-by-One Variation

把有限集中的置换推广到可数集上 ,引入基轮换、轮换及变换的可数次合成等概念的定义 .并用命题的形式揭示了任意可数集的一一变换总是它的基轮换的可数次合成 .

The permutation of the finite set is introduced into the denumerable set as well as the definition of the basic rotation, the rotation and the composition of the countability. And the one by one of the orbitrary denumerable set is always revealed to be the composition of the countability of its basic rotation in the form of proposition. And several pieces of the nature of the basic rotation together with some related propositions are also offered.
