Abstract：
The SU(3) chiral quark model is used to invesdgate the structures of three six-quark systems-H dibaryon d' and d' states. The non-perturbative QCD effects such as SU(3) chairl field coupling and the vector-coupling effect on the confinement potential are studied. The results show that the SU(2) chiral field coupling makes six-quark system more stable, but the SU(3) chiral"cloud" is not favourable to form the dibaryons.
