摘　　要：本文用量子群Uqp（u2）模型对193-194T1超形变核的转变谱的跃迁能级、运动学、动力学转动惯量随转动频率的系统分析研究，理论植与实验很好地吻合，证实了量子群Uqp（u2）理论模型的适用性。还进一步计算研究了193-194T1核软度系数与形变参数的关系。In this paper, the validity of an Uqp(u2)model for the rotating superdeformed nuclei193-194 TI is systematically analyzed by investigating the transition energies, the kinematic and dynamic moments of inertia variation with rotational frequency. The results show tha the theoretical values obtained from the Uqp(u2)model are in a good accordance with the experimentl findings. Further more, a relationstip between the parameters of deformations and the nuclear softness is also established, the softness of193-194 T1 was calculated.
