摘要：

The neutrino mass spectrum is reanalyzed in supersymmetric models with explicit trilinear R violation. Models in this category are argued to provide simultaneous solutions to the solar and atmospheric neutrino anomalies. It is shown specifically that the large mixing and hierarchical masses needed for the vacuum solution of neutrino anomalies arise naturally in these models without requiring any additional symmetries or hierarchies among the trilinear couplings.
