White - black hole is a new macro object which is predicted the existence by the vector model for gravitational field. In this paper we present the existence and research numerically the surface oscillation of the white- black hole in the model. Results show that the surface oscillation is quasi-harmonic, the larger white - black hole mass is the larger its period and its period reduces with the reduction of the radius. There is a critical radius at which the white-black hole stops oscillating and rapidly increases its radius.
