Burgers-Fisher方程的新精确解

The New Exact Solutions for Burgers-Fisher Equation

利用改进的tanh函数方法将Burgers-Fisher方程化为一阶非线性常微分方程组。通过求解这个非线性常微分方程组,获得了Burgers-Fisher方程新的精确类孤子解和三角函数解。

In this paper, by using the extended tanh-function method, the general Burgers-Fisher equations are reduced to first-order nonlinear ordinary differential equations, and then the new exact solutions for these equations, which include exact soliton-like and triangle function solutions, are obtained through solving these ordinary differential equations.
