摘　　要：利用粒子 -转子模型研究三轴超形变核态 ,讨论了区别轴对称超形变和三轴超形变可能的实验信息 .为了直接从实验上识别三轴超形变带 ,必须同时测量能谱和电磁跃迁几率 .Current developments in triaxial superdeformed states in nuclei are discussed from a theoretical perspective. A detailed analysis of superdeformed triaxial bands is made with particle-rotor model. Experimental information which may differentiate triaxial superdeformation from axially-symmetric superdeformation is disussed. In order to identify the superdeformed triaxial bands both the energy spectra and electromagnetic transition probabilities should be measured.
