In the first part we have tried to put forward a definition of the euphony and further to analyze its position in the study of rhetoric; In the second part, the euphony phenomenon has been classified according to different dimensions such as function and culture, etc; In the third part we have given the euphonys characteristics wider coverage to deal with the different reflections in the fields of pronunciation, grammar, semantic meaning and context; In the fourth part, we have analyzed the formation of euphony from the point of aesthetics, psychology, social culture and linguistic characters, etc; Base on what is discussed above the euphony phenomenon both in different folkways and styles of writing have been studied in the fifth and sixth parts; And the final seventh part is the conclusion.

In this paper,by using the idea of F-expansion method (where F is a known solution of an ordinary differential equation with fourth positive power nonlinearity),the problem of seeking the exact solutions of the generalized BBM equation with any positive power nonlinearity is changed into seeking the exact solutions of an ordinary differential equation with fourth positive power nonlinearity.

利用F-展开法的思想(F是一阶四次常微分方程的一个解)，将求含有任意次正幂项非线性广义BBM方程的精确解转化为求一阶四次常微分方程的精确解。
