Abstract: A kind of adhesive, zero spread of the existence of the generalized local solution Boussinesq equations is considered. Using the regularization method, the compression mapping principle and the classical energy estimation method, the adhesive, zero spread of the local existence of the generalized Boussinesq equations are derived. And using the technique of Sobolev inequality, a blasting principles is obtained. The results of the study reveals a kind of special physical phenomenon of fluid movement.

Key words: Boussinesq equations, regularization, energy estimation method, local well-posedness
