【Abstract】 Generalized Schrdinger-Boussinesq equations are widely used in the physical fields to describe various physical processes in Laser and plasma,such as Langmuir field amplitude and intense electromagnetic waves and modulational instabilities,etc.In this paper,by using the extended Jacobi elliptic founctions expansion methods,and with the aid of mathematical software,a series of new compound Jacobi formal exact solutions of the Schrdinger-Boussinesq equations are obtained.Some of which were degenerated to the solitary wave solutions and the single triangle function solutions extreme cases.Thus this method can replenish,simplify and develop the known results.更多还原
