摘要：

We present a preliminary analysis of the heavy-heavy spectrum and heavy-light decay constants in full QCD, using a tadpole-improved SW quark action and an RG-improved gauge action on a 16(3) x 32 lattice with four sea quark masses corresponding to m(pi)/m(p) approximate to 0.8, 0.75, 0.7, 0.6 and a(-1) approximate to 1.3 GeV. We focus particularly on the effect of sea quarks on these observables.
