We investigate the structure of H particle within the framework of chiral SU (3) quark mod‐el and the extended chiral SU (3) quark model .Firstly ,the different mechanisms of short -range in‐teractions ,vector exchange or one‐gluon exchange ,are analyzed .Secondly ,the different confinement potentials and channel‐coupling effects are studied .Finally ,the effects of the mixing of scalar mesons on the H particle are investigated .The results show that the further exact information from experi‐ments will be helpful in deciding the different confinement potentials and the mixing of scalar mesons in our models .
