The electrostatic shielding is used as the analogy of the theory of quark shielding in this paper. With the combination of the method of variable division and the mirror-image method, we obtain the solution of the Poisson equation whose boundary condition is conductor spherical face connected with ground,and the electric dipole was confined in.The potential representation yielded from the electric dipole and its induction in the sphere is obtained.Three situations are analyzed, calculated and discussed according to the electric dipole's positions in the sphere. This paper also concludes the potential representation made by the electric dipole and its induction near the surface of the conductor. In order to see the mirror-image feature obviously, we transforms the potential representation by mathematical methods of physical, and analyzes the space positions of mirror-image charge and mirror-image dipole.
