  We analyse the quark mass hierarchy and CKM matrix using the universal Yukawa
coupling model with small violations precisely. We estimate the ranges of the
values of 8 violation parameters (delta1u, delta2u, delta3u, delta1d, delta2d,
delta3d, phi2, phi3) in our quark mass matrices satisfying quark mass ratios
and CKM matrix, where phi2, phi3 are phases. Without these phases, the solution
  satisfying quark mass ratios and CKM matrix is not obtained. These parameters
obtained can explain the CP violation effects.
