英文摘要	In the constituent quark model, light baryons are considered as the systems of the constituent quarks with confining interaction and with a chiral interaction mediated by Goldstone bosons. Here the masses of the N and Delta and their splitting are investigated based on a relativistic quark model approach with inclusion of pion meson cloud. Pseudoscalar pi-quark interaction is employed to study the coupling between the mucleon and the pi. The results show the contributions of the one-gluon-exchange potential and of the pion meson cloud to the N-Delta mass splitting. Moreover, our numerical analyses indicate a difference between the relativistic and the nonrelatiyistic treatments.
