摘要：

We conclude our analysis of the N-t = 6 equation of state (EOS) for two flavor QCD, first described at last year's conference. We have obtained new runs at am(q) = 0.025 and improved runs at am(q) = 0.0125. The results are extrapolated to m(q) = 0, and we extract the speed of sound as well. We also present evidence for a restoration of the SU(2)xSU(2) chiral symmetry just above the crossover, but not of the axial U(1) chiral symmetry.
