摘要：

We consider the case that the solar neutrino deficit is due to vacuum oscillations. The lepton mass matrices with nearly bimaximal mixings are needed in order to explain both the solar and atmospheric neutrino deficit. A texture with the symmetry of flavor democracy or S-3 has been investigated by taking account of the symmetry breaking terms of the charged lepton mass matrix. It is found that predicted mixings can be considerably changed from the neutrino mixings sin(2)2 theta(.)similar or equal to 1 and sin(2)2 theta(atm)similar or equal to 8/9 at the symmetric limit. The correlation between \U-e3\ and \U-e1 U-e2*\ is also presented. The test of the model is discussed by focusing on the three flavor analyses in the solar neutrinos, atmospheric neutrinos, and long baseline experiments. [S0556-2821(99)07501-3].
