最近的中微子数据已经有利于接近双峰混合，这表明中微子质量矩阵的一种简单形式。在这种矩阵形式的激励下，我们研究了夸克和轻子的质量矩阵与中微子的质量矩阵具有相同形式的可能性。质量矩阵形式受离散对称性${\marthm {Z}}_{3}$和置换对称性${\marthm {S}}_{2}的约束。当然，该模型导致轻子扇区几乎是双峰混合，而对于夸克扇区，它可以导致CKM混合矩阵和质量的合理值。
Recent neutrino data have been favorable to a nearly bimaximal mixing, which suggests a simple form of the neutrino mass matrix. Stimulated by this matrix form, the possibility that all the mass matrices of quarks and leptons have the same form as in neutrinos is investigated. The mass matrix form is constrained by a discrete symmetry ${\mathrm{Z}}_{3}$ and a permutation symmetry ${\mathrm{S}}_{2}.$ The model, of course, leads to a nearly bimaximal mixing for the lepton sectors, while, for the quark sectors, it can lead to reasonable values of the CKM mixing matrix and masses.
