英文摘要	We show how the nearly bi-maximal mixing scenario comes out naturally from gauged SO(3)(F) flavor symmetry via spontaneous symmetry breaking. An interesting relation between the neutrino mass-squared differences and the mixing angle, i.e., Deltam(mue)(2)/Deltam(tau mu)(2) similar or equal to 2/U-e3/(2) is obtained. The smallness of the ratio (or /U-e3/) can also naturally be understood from an approximate permutation symmetry. Once the mixing element /U-e3/ is determined, such a relation will tell us which solution will be favored within this model, The model can also lead to interesting phenomena on lepton-flavor violations.
