By using the group-chain, the wavefunctions of the 4f〓 configuration for RE ions are also expressed as linear combinations of group-chain basis functions in Butler's irreducible representation notation. The matrix elements of the CF Hamiltonian then are calculated by means of the Wigner-Eckart theorem and factorization lemma of the jm factors. Before the CF level fitting, a point-charge calculation of the conventional CF parameters B〓 has been performed by means of the lattice-sum technique from the known crystal structure data. The corresponding parameters in the group-chain are calculated by the conversion relationship between two schemes that proved identical in essence, which are usually used as initial values in the fit to the experimental levels. The ratios of the same k-value CF parameters are suggested as the constraint conditions in the fit, in order to utilize fully the symmetry distortion degree of the studied system.

本论文通过对散布在《计算之书》各个章节中的三类不定问题进行系统梳理之后发现：《计算之书》"买鸟问题"的解法是"合金法"，此方法是用来解答三种以上钱币配置问题整数解的情况；"捡钱包问题"和"买马问题"是一次不定方程组问题，解答过程相当于现今的一次方程组问题，通常通过"消参"即可解决，在历史上没有对不定分析问题的研究产生明显影响；而"剩余问题"是以占卜猜数问题的形式呈现计算过程，虽然斐波那契没有对不定问题进行深入研究，但正是因为这些问题的趣味性，以及斐波那契某些解法的独创性而引起以后欧洲学者对此类问题的兴趣，并由此将不定分析问题研究引入欧洲。
