In Chapter l,we in-troduces self mappings on an interval, the roots of the functions, functional equations and the embedding flow. 对迭代的研究涉及线段上的自映射，迭代根与迭代函数方程，迭代根与嵌入流等问题。
As an application, it is proved that a continuous map of an interval is chaotic iff it is distributively chaotic in a sequence. 给出紧度量空间上连续映射按序列分布混沌的一个充分条件，并证明区间连续自映射是混沌的当且仅当它是按某序列分布混沌的。
