Burgers-Fisher方程新的显式精确解

New explicit and exact solutions to Burgers-Fisher Equation

使用扩展双曲函数法,获得了Burgers-Fisher方程的显式精确解,推广了扩展tanh方法和双曲函数法的结果,获得一些新的精确解,其中u2至u8为新的孤立波解,u9至u18为三角函数型解.

In this paper, the extended hyperbolic function was used to seek for exact solutions of the Burgers-Fisher Equation. We could obtain more new solutions to the solutions which were obtained by using the hyperbolic function method and the extended tanh method. Among u2 to u8 are new solitary wave solutions, u9 to ul8 are triangle funtion solutions.
