标题： Cascade Global Symmetry and Quark Mass Hierarchy

摘要： 级联全局对称性和多真空期望值相结合，产生了夸克质量矩阵的{\bf 初始}纹理。 初始纹理零点（{\bf ITZ)}都在$10^{-3}m_t$或更小的阶次。 {\bf 辐射修正}作为完整质量矩阵的来源的可能性被简要讨论。 显示英文摘要

摘要： Cascade global symmetry and multi-vacuum expectation values are combined to produce an {\bf initial} texture of the quark mass matrices. Required corrections to the initial texture zeros ({\bf ITZ)} are all at the order of $10^{-3}m_t$ or less. The possibility of {\bf radiative corrections} as the source of the complete mass matrices is briefly discussed.
