Obtaining new exact solution of Boussinesq eqution by(G′/G)-expansion method

通过引入(G′/G)的展开法,构造出Boussinesq方程的新精确解.而文献[21]给出的Boussinesq方程的解仅是上述结果的一种特殊情况.这种方法也可用于求其他非线性发展方程的新精确解.

By introducing and extending the（G′/G）-expansion method,the new exact general solution are constructed for Boussinesq eqution.The Iiterature ＇s result is a special case of above result for the Boussinesq equation.This method also can be used to find new exact solution to other nonlinear evolution equations.
