It is found that σ and π0 without electric charges have electromagnetic interaction effects coming from their internal structures. A general Lorentz transformation relative to external sources $$J_{\rm gauge}=(J_{A_\mu},J_{A_\mu^\kappa})$$ is derived, using the general Lorentz transformation and the four-dimensional current of nuclear matter of the ground state with J gauge = 0, we give the four-dimensional general relations between the different currents of nuclear matter systems with J gauge≠ 0 and those with J gauge = 0. The relation of the density's coupling with external magnetic field is derived, which conforms well to dense nuclear matter in a strong magnetic field. We show different condensed effects in strong interaction about fermions and antifermions, and give the concrete scalar and pseudoscalar condensed expressions of σ0 and π0 bosons. About different dynamical breaking and spontaneous vacuum symmetry breaking, the concrete expressions of different mass spectra are obtained in field theory. This paper acquires the running spontaneous vacuum breaking value σ′0, and obtains the spontaneous vacuum breaking in terms of the running σ′0, which make nucleon, σ and π particles gain effective masses. We achieve both the effect of external sources and nonvanishing value of the condensed scalar and pseudoscalar paticles. It is deduced that the masses of nucleons, σ and π generally depend on different external sources.
