    结合一种广泛应用的插值与外推方法---径向基函数法,我们发现一些常用的原子核质量模型的精度能够被进一步提高大约10%~40%, 其中四个质量模型:WS3, FRDM, DZ28, WS*对2149个已测原子核质量的均方根偏差达到大约200keV。与此同时,对于未知核质量的预言,这些不同模型相互之间的偏差也大大减小。

    With the help of the radial basis function (RBF) and the Garvey-Kelson relation, the accuracy and predictive power of some global nuclear mass models are significantly improved. The rms deviation between predictions from four models and 2149 known masses falls to ∼200 keV. The AME95-03 and AME03-Border tests show that the RBF approach is a very useful tool for further improving the reliability of mass models. Simultaneously, the differences from different model predictions for unknown masses are remarkably reduced and the isospin symmetry is better represented when the RBF extrapolation is combined.
