利用锕系偶偶核基带转动谱的实验数据，对两参数ａｂ公式用线性拟合的方法进行计算，并与非线性拟合进行比较。结果表明，对ａｂ公式，线性拟合也不失为一种较好的方法。计算结果还表明，吴－－曾提出的三种不同形式的三参数公式所得的结果相差不大，但都较ａｂ公式的计算结果更符合实验事实。 Based on the experimental data of the rotation spectra of the actinine even-couple nuclei, the two-parameter ab formula was calculated by linear fitting method and compared with the non-linear fitting. The results show that, for the ab formula, the linear fit is also a good method. The calculation results also show that the results of three different types of three-parameter formulas proposed by Wu and Wu have little difference, but they are more in line with the experimental results than those calculated by ab formula.
