摘要
文献[3]和文献[4]中的孤波解是用双曲正切表达的孤波解,本文则是由正切函数变换出发而得到的双曲余切表达的Fisher方程的新孤波解.
The solitary wave solutions in Literature 1 and 2 axe expressed by hyperbola tangent, while this paper proposes a new kind of solitary wave solution of Fisher Equation by using hyperbola cotangent derived from tangent function variation.
