摘要：

By using effective chiral Lagrangians with a suitable incorporation of the scaling property of QCD, we establish the approximate in-medium scaling law, m-sigma*/m-sigma almost-equal-to m(N*)/m(N) almost-equal-to m-rho*/m-rho almost-equal-to m-omega*/m-omega almost-equal-to f-pi*/f-pi. This has a highly nontrivial implication for nuclear processes at and above nuclear-matter density. Some concrete cases are cited in this paper.
