我们计算了SU(3)规范理论在一阶定义相变点的冷热相之间的能隙（潜热）和压力隙。我们在相变点附近进行了模拟，晶格尺寸在时间方向上，8和12，并将结果外推到连续统极限。我们还研究了空间体积依赖性。用非摄动各向异性系数的导数法计算了能量密度和压力。采用多点加权法确定各向异性系数。我们证实各向异性系数接近微扰值。我们发现当使用非微扰各向异性系数时，压力间隙在所有值处都消失了。在大格子上，潜热的空间体积依赖性较小。对连续统极限进行外推，得到和。
We calculate the energy gap (latent heat) and pressure gap between the hot and cold phases of the SU(3) gauge theory at the first order deconfining phase transition point. We perform simulations around the phase transition point with the lattice size in the temporal direction, 8 and 12 and extrapolate the results to the continuum limit. We also investigate the spatial volume dependence. The energy density and pressure are evaluated by the derivative method with nonperturabative anisotropy coefficients. We adopt a multipoint reweighting method to determine the anisotropy coefficients. We confirm that the anisotropy coefficients approach the perturbative values asincreases. We find that the pressure gap vanishes at all values ofwhen the nonperturbative anisotropy coefficients are used. The spatial volume dependence in the latent heat is found to be small on large lattices. Performing extrapolation to the continuum limit, we obtainand.
