Abstract
The SU(3) chiral quark model is used to investigate the structures of three six-quark systems-H dibaryon, d and d' states. The non-perturba tive QCD effects such as SU(3) chairl field coupling and the vector-co upling effect on the confinement potential are studied. The results sh ow that the SU(2) chiral field coupling makes six-quark system more st able, but the SU(3) chiral ''cloud'' is not favourable to form the dib aryons.
