摘要：

对Fisher型方程，首先说明在不同的幂变换下得到的是同一族孤波解，然后给出了一个新假设，得到了Fisher型方程的二族显式精确解.

关键词: Fisher型方程, 幂变换, 假设, 孤波解.

Abstract:

This paper first proves that the solitary wave solutions to Fishertype equation followed by use of different power transformations are of the same hierarchy, then by giving a new hypothesis, obtains two hierarchies of explicit exact solutions to Fisher-type equation.

Key words: Fisher-type equation, Power transtormation, Hypothesis solitary wave solution.
