All kinds of fields (electromagnetic field, gravitational field and torsion field) can be regarded as the behaviors of physical vacuum under different polarized conditions. If one charged particle in vacuum spins to lead to the charge polarization of the vacuum , it takes the form of electric field ; if the move source is mass, by which the spin leads vacuum to the vertical polarization, it takes the form of gravitational field; If the spin is self-spinning to lead vacuum to the horizontal polarization, it takes the form of torsion field.
