关于G′/G展开法的注解

A note on G′/G-expansion method

研究求解非线性偏微分方程精确解的G′/G展开法和经典的Tanh方法,发现这两种方法是等价的.通过这两种方法可求得相同的精确解,并给出两种解的系数之间的关系.

The G′/G-expansion method and classical Tanh method were investigated in connection with their use for finding the exact solutions to nonlinear partial differential equations and it was found that these two methods were equivalent.An identical exact solution would be given by using these two methods.And the relation of the coefficients in the exact solutions with these two methods was also given.
