Abstract: A paramatrization of KM mixing matrix was proposed by observing the regulari ties of the matrix exposed by experiments.Some physical implications on these new parameters are discussed.The phenomenological constraints on the down-quark mass matrix in the weak interaction base were investigated.A model of the down-quark mass matrix was suggested.in which the KM mixing matrix elements can be estimated in terms of the down-quark masses.The Results obtained in this model agrees with experimental data.
