By using effective chiral Lagrangians with a suitable incorporation of the scaling property of QCD, we establish the approximate in-medium scaling law, mσ*/mσ≊mN*/mN ≊mρ*/mρ≊mω*/mω≊fπ*/fπ. This has a highly nontrivial implication for nuclear processes at and above nuclear-matter density. Some concrete cases are cited in this paper.
