本文介绍的数据集包含了296个核素的最新测量质量数据，这些数据来源于2021年至2024年间发布的40篇参考文献。这些数据用于评估和比较多种相对论和非相对论密度泛函的性能，包括PC-PK1、TMA、SLy4、SV-min、UNEDF1和PC-L3R。通过使用最新的变形相对论连续体Hartree-Bogoliubov理论（DRHBc），PC-PK1和PC-L3R的描述准确性优于其他泛函，能够更准确地描述核质量。数据集的创建过程涉及从40篇参考文献中收集和分析数据，并使用先进的DRHBc理论进行计算和评估。该数据集的应用领域包括核物理学、天体物理学以及核能应用等，旨在解决核质量预测的精确性和可靠性问题。

The dataset presented herein contains the latest measured mass data of 296 nuclides, sourced from 40 references published between 2021 and 2024. This dataset is utilized to evaluate and compare the performance of a range of relativistic and non-relativistic density functionals, including PC-PK1, TMA, SLy4, SV-min, UNEDF1, and PC-L3R. By adopting the state-of-the-art deformed relativistic continuum Hartree-Bogoliubov theory (DRHBc), PC-PK1 and PC-L3R demonstrate superior descriptive accuracy compared to other functionals, enabling more precise characterization of nuclear masses. The development of this dataset entails collecting and analyzing data from the 40 references, followed by calculations and evaluations using the advanced DRHBc theory. The application scope of this dataset covers nuclear physics, astrophysics, nuclear energy applications and other related fields, with the goal of addressing the accuracy and reliability issues in nuclear mass prediction.
