这篇文章的重点是在RHIC能量下的统计模型计算结果，包括最近可用的实验数据。先前的粒子屈服比计算与SPS和较低能量下的测量结果一致，表明复合体系在冻结时具有高度的化学平衡。讨论了下馈污染对模型参数的影响，并说明了各比值对模型参数（T, μB）的敏感性。
This contribution focuses on the results of statistical model calculations at RHIC energies, including recently available experimental data. Previous calculations of particle yield ratios showed good agreement with measurements at SPS and lower energies, suggesting that the composite system possesses a high degree of chemical equilibrium at freeze-out. The effect of feed-down contamination on the model parameters is discussed, and the sensitivity of individual ratios to the model parameters (T, μB) is illustrated.
