ON THE APPLICATIONS OF STRONG PCAC

Abstract: In this article,we study the field-current relations of the 4-divergence of the axial vector currents.If there exist a series of radial excited state,then 4-divergence of the axialvector current will be identical with the fields of all exciting pseudo-scalar mesons[1].From this relation,we can derive a definite correction to the matrix elements which obtained by PCAC and low energy theorem in the current algebra calculations.Concrete calculations show all results obtained by those corrections agree with the ex-periments.
