摘要	Multi-dimensional constrained covariant density functional theories were developed recently. In these theories, all shape degrees of freedom beta(lambda mu) deformations with even mu are allowed, e.g., beta(20), beta(22), beta(30), beta(32) beta(40), beta(42), beta(44), and so on and the CDFT functional can be one of the following four forms: the meson exchange or point-coupling nucleon interactions combined with the non-linear or density-dependent couplings. In this contribution, some applications of these theories are presented. The potential energy surfaces of actinide nuclei in the (beta(20), beta(22), beta(30)) deformation space are investigated. It is found that besides the octupole deformation, the triaxiality also plays an important role upon the second fission barriers. The non-axial reflection-asymmetric beta(32) shape in some transfermium nuclei with N = 150, namely (246)cm, (248)cf., Fm-250, and No-252 are studied.
