二阶、反转和时间反转三个相互垂直的对称轴可以用来构造由d2h(Td)表示的双点群。在平均场(Hartree-Fock)理论中，分析了偶费米子系统和奇费米子系统中该群的对称性和对称性破缺效应。我们列举了局域单体密度的空间对称性和电磁矩的对称性，这些对称性出现在部分或全部d2小时(TD)元素表示自洽平均场对称时。
Three mutually perpendicular symmetry axes of the second order, inversion, and time reversal can be used to construct a double point group denoted by D2h(TD). Properties of this group are analyzed in relation to the symmetry and symmetry-breaking effects within the mean-field (Hartree-Fock) theories, both in even and odd fermion systems. We enumerate space symmetries of local one-body densities, and symmetries of electromagnetic moments, that appear when some or all of the D2h(TD) elements represent self-consistent mean-field symmetries.
