Then we find out the exact bounded wave solutions for WBK equation in chapter four. According to the theory of dynamical system, we investigate the explicit exact traveling wave solutions of nonlinear wave equations by using the characters of the closed trajectory connecting equilibrium points and the relations between obits and traveling waves.

在对系统进行定性分析、了解了系统所有可能解的大致形态的基础上，论文第四章给出了WBK方程的精确有界解，应用动力系统理论，利用连接平衡点的闭轨线的特点结合轨线与行波之间的对应关系来研究非线性波方程行波解的有界性及精确的显式表达式。

Results After improving, lithotripsy could recycle no-air water to be filled into shock wave generator. It not only increased shock wave conducting and stone breaking efficiency, but also decreasee air content in shock wave generator and outer conduct passway, and decreased bubble forming, thus reducing complication in more rational procedures.
