通过使用改进的分数阶sub-equation方法寻求一些非线性分数阶演化方程的精确解,如分数阶Burgers方程、耦合分数阶Burgers方程与非线性分数阶Klein-Gordon方程等,并得到了这些非线性分数阶演化方程的新解.
By using an improved method of fractional sub-equation, some nonlinear fractional evolution equations are solved including fractional Burgers equation, coupled fractional Burgers equation and fractional Klein-Gordon equation. New exact solutions of these nonlinear fractional nonlinear evolution equations are obtained.
