最近在产生主场合奏方面取得了重大进展。这必须与有效的技术相结合，以计算具有大体积的规范场配置上的可观测量。本文给出了用N_{f}=2+1$稳定化的Wilson费米子模拟的物理体积高达$（18\，\mathrm {fm}）^4$和$m_\pi L$高达$25$的大体积和主场系综的强子观测量（包括强子质量和介子衰变常数）的计算结果.我们得到的子百分之确定单规格配置与位置空间技术，体积平均值和主字段误差估计的结合使用。
Substantial progress has been made recently in the generation of master-field ensembles. This has to be paired with efficient techniques to compute observables on gauge field configurations with a large volume. Here we present the results of the computation of hadronic observables, including hadron masses and meson decay constants, on large-volume and master-field ensembles with physical volumes of up to $(18\,\mathrm{fm})^4$ and $m_\pi L$ up to $25$, simulated using $N_{\mathrm{f}}=2+1$ stabilized Wilson fermions. We obtain sub-percent determinations from single gauge configurations with the combined use of position-space techniques, volume averages and master-field error estimation.
