self map的用法和樣例：
例句
- In Chapter l,we in-troduces self mappings on an interval, the roots of the functions, functional equations and the embedding flow.
對迭代的研究涉及線段上的自映射，迭代根與迭代函數方程，迭代根與嵌入流等問題。 - As an application, it is proved that a continuous map of an interval is chaotic iff it is distributively chaotic in a sequence.
給出緊度量空間上連續映射按序列分布混沌的一個充分條件，并證明區間連續自映射是混沌的當且僅當它是按某序列分布混沌的。
