主　　题：equation. Boussinesq equation 

摘      要：For a lattice Boussinesq equation,we introduce a simple-parameter invertible transformation by which the equation is transformed into an extended *** new equation admits solitons and nonzero quasi-rational solutions,both in Casoratian *** solutions can be reverted to those of the lattice Boussinesq equation.
