In chapter three,we have derived a generalized dual London equation for the Abelian "electric" field A_μfrom the effective dual Abelian-Higgs model.The approximative result and the numerical simulation result as well as their figs were shown via solving the dual Abelian-Higgs model with different methods.Hereby the vortex solution of the chromo-electric field and the vortex energy density were also discussed.Finally,we have studied the dual Abelian-Higgs model with additional vacuum constant,and have unpuzzled the vacuum constant corresponding to the bag model.When the quark sources is introduced, the vacuum constant in the MIT bag model is proportional to the quartic of the monopole mass.

First, we deduce a formula for vacuum polarization pressure as f ＝ G m M （ r ∕ r ＋ v ∕ c ）∕ r 2 , based on the isotropy of distribution of neutrinos ν0 in the lowest energy state in the physical vacuum, requested by the Pauli exclusion principle. Then, we deduced the metric equation of the general relativity and the equivalence principle according to this formula. Further, we demonstrate that this vacuum polarization pressure is the gravitation in general meaning.
