摘　　要：利用Ｂｅｃｋｅｒ等人的角动量与转动频率的二参量公式和吴崇试、曾谨言的二参量转动谱公式，分别对８６Ｚｒ的ＳＤ１，ＳＤ２，ＳＤ４，１６３，１６５，１６７Ｌｕ以及１７１Ｔａ，１７３Ｒｅ的三轴超形变带作最小二乘法拟合。Transition energies of triaxial superdeformed bands in 86 Zr as well as 163,165,167 Lu and 171 Ta, 173 Re were fitting by the power series expansion of I in odd powers of E r /2 and the two parameter expression for rotational spectra.Level spins for these triaxial superdeformed bands were determined by the least squares fitting.
