1. Purpose : In order to obtain a clue to unified understand of quarks and leptons, aunified description of quark and lepton mass matrices is investigated.Results :(1) We have reached a new model, "democratic-seesaw-mass-matrix model" (DSMM model) by combining a mass-generation scenatio for Koide's charged lepton mass formula with an idea of a "democratic quark mass matrix model".(2) Quark masses and their family mixings have been evaluated on the basis of the DSMM model, and satisfactory results have been obtained.(3) Neutrino masses and their mixing have been investigated by extending the DSMM model to neutrinos. The model naturally be understand the large nu_<mu>-nu_<gamma> mixing which has been suggested by the atmospheric neutrino data at KAMIOKANDE.As the mass-generation mechanism which gives the DSMM from, we have proposed a non-standard Higgs mechanism, "H (3) -family noned Higgs boson model", and investigated possible new effects which are induced by the new Higgs bosons.

1. 目的：为了获得统一认识夸克和轻子的线索，研究了夸克和轻子质量矩阵的统一描述。结果：(1)将Koide带电轻子质量公式的质量生成情景与“民主夸克质量矩阵模型”的思想相结合，得到了一个新的模型“民主-跷跷板-质量矩阵模型”（DSMM模型）。(2)在DSMM模型的基础上对夸克质量及其族混合进行了评价，得到了满意的结果。(3)通过将DSMM模型扩展到中微子，研究了中微子质量及其混合。该模型可以很自然地理解神冈望远镜的大气中微子数据所提示的nu_<mu>-nu_<gamma>的大混合。作为给出DSMM的质量生成机制，我们提出了一个非标准的希格斯机制，即“H(3)族非希格斯玻色子模型”，并研究了新希格斯玻色子可能引起的新效应。
