摘要：
We study the relations between low-energy constants in the chiral Lagrangians with ?(1232) and those in the quark-level description model up to the third chiral order. Ten structure correspondences are involved in getting the relations. This situation is more complicated than the spin 1/2 baryon case. The obtained results may help to further investigations involving the ?(1232) baryons.
