根据夸克和轻子的质量矩阵都具有相同的结构这一观点，我们反对夸克扇区中的质量矩阵形式与轻子扇区中的质量矩阵形式具有某种不同的结构的传统看法，在离散对称性和扩展味假设下，提出了夸克和轻子质量矩阵的普适结构对称性纹理由三个参数（包括相位参数）描述。根据这个结果，我们研究了中微子的质量和混合。
Against the conventional picture that the mass matrix forms in the quark sectors will take somewhat different structures from those in the lepton sectors, on the basis of the idea that all the mass matrices of quarks and leptons have the same texture, a universal texture of quark and lepton mass matrices is proposed by assuming a discrete symmetry ${Z}_{3}$ and an extended flavor $2\ensuremath{\leftrightarrow}3$ symmetry. The texture is described by three parameters (including the phase parameter). The neutrino masses and mixings are investigated according to this ansatz.
