A natural gauge fixing is explicitly identified in the decomposition and intrinsic relation between Abelian projection and the symmetry-breaking of the Yang-Mills dynamics in infrared limit is illustrated. A London like equation is derived for chromo-electronic field. Key words Yang-Mills field decomposition, Abelization, London like equation 1 Introduction field between two colored sources is squeezed into a fluxtubes(vortices) and the later permanently con- Since quantum chromodynamics(QCD) has been fines colored sources(quarks) within hadrons.
