基于手征有效理论的朴素维数分析，当适用于核能密度泛函时，规定了自然单位和贡献的层次结构，可用于约束广义泛函的拟合。通过应用这些单位，一个大样本的Skyrme参数化检查的自然性，这是一阶无量纲耦合常数的信号。大部分的参数被认为是自然的，与其他确定的基本规模一致。从单位的显着偏差与特定泛函的相应项的缺陷或与不完整的优化过程。
Naive dimensional analysis based on chiral effective theory, when adapted to nuclear energy density functionals, prescribes natural units and a hierarchy of contributions that could be used to constrain fits of generalized functionals. By applying these units, a large sample of Skyrme parametrizations is examined for naturalness, which is signaled by dimensionless coupling constants of order one. The bulk of the parameters are found to be natural, with an underlying scale consistent with other determinations. Significant deviations from unity are associated with deficiencies in the corresponding terms of particular functionals or with an incomplete optimization procedure.
