摘　　要：反射不对称壳模型推广到包括轴对称破缺。在这一发展中,壳模型空间由三轴形变的多准粒子基所构建,实现了对旋称反转、手征带和摇摆带的统一的壳模型描述。在壳模型框架下,三轴性的引入,严格的三维投影和直到六准粒子的组态混合,使该理论可以在一个新的水平上研究高速转动三轴形变核中的物理现象。The Reflection Asymmetric Shell Model has been generated to include the axial symmetry break. In this new development, the shell model space is spanned by the triaxially-deformed multi-quasi-particle basis. A unified shell model description of the signature inversion, chiral and wobbling bands can be achieved. In the frame work of shell model, the inclusion of the triaxiality, the exact three dimensional projection and up to six quasiparticle configuration mixing make the theory powerful to study the phenomena in highly rotating triaxial nuclei at a new level.
