The regularity criteria of the three-dimensional incompressible Boussinesq equations are mainly considered. It is proven that if one component of the velocity field satisfies ∫

the local solution can be continuously extended to the endpoint. This result improves and develops some known regularity criteria of the threedimensional incompressible Boussinesq equations
which is a supplement to the regularity theory.
