| 摘 要： | 在求函数的迭代根的问题中,只有少数的问题可以通过直接计算得到形式比较简单的结果,但是对于复杂一点的初等函数,要直接计算函数迭代根将是件非常困难的事情。本文将利用“相似变換”,可以把求一个较复杂的迭代根的问题转化为一个比较简单函数迭代根的问题。

| Abstract: | Only a few of it can be obtained a simple form of result through computing directly among the problems of iterative root. But, for a relatively comlex elementary tunction it too difficult to compute its iterative root. In this paper we will turn it into a simple one through similar translation. The knowledge of relative unstable spot was also used in this paper. The mainly result is to obtain a general method to resolve the fractional function |
