| Abstract: | From the energy momentum conservation law of the electromagnetic fields,the fourth dimension of Lorentz force's component form is derived.By inducing the fourth dimension of momentum flow densiry tensor,and then through the combination of every force's components form,a covariant form of evergy momentum conversation law of the electromagnetic fields can obtained. |
