摘要：

We present results on an analysis of the decay constants f(Bd) and f(Bs), with two flavours of sea quark. The calculation has been carried out on 3 different bare gauge couplings and 4 sea quark masses at each gauge coupling, with m(pi)/m(rho) ranging from 0.8 to 0.6. We employ the Fermilab formalism to perform calculations with heavy quarks whose mass is in the range of the b-quark. A comparison with a quenched calculation using: the same action is made to elucidate the effects due to the sea quarks.
