英文摘要	If the neutrino mass spectrum turns out to be m(3) < m(1) < m(2), it may be relabeled as m'(1) < m'(2) < m'(3) such that all the masses of fundamental fermions with the same electrical charges are in order. In this case the columns of the 3x3 lepton flavor mixing matrix U should be reordered accordingly, and the resulting pattern U' may involve one or two large mixing angles in the standard parametrization or its variations. Since the Majorana neutrino mass matrix remains unchanged in such a mass relabeling, a possible mu-tau reflection symmetry is respected in this connection and its breaking effects are model-independently constrained at the 3 sigma level by using current experimental data.
