摘要：

We have performed four-flavor, full QCD simulations on 163 × Nt lattices with Nt = 4 and 6 and with quark masses ma = 0.01, 0.025, 0.0375 and 0.05 where a is the lattice spacing. For Nt = 4 a first-order transition is seen for all four mass values and the chiral m→0 limit is easily recognized for the two lightest mass values. For Nt = 6 we see a weak first-order transition for ma = 0.01 but find that it has disappeared for ma = 0.025 showing that the transition becomes more easily destabilized by the quark mass as the lattice spacing is reduced. © 1990.
