英文摘要	Some recent progresses in our understanding of penta-quark components in baryons is briefly reviewed. The diquark cluster picture for the penta-quark components in baryons gives a natural explanation not only to the empirical indications for a positive strangeness magnetic moment mu(s) and positive strangeness radius of the proton but also the long-standing mass-reverse problem of N(1535), N(1440) and Lambda(1405) resonances as well as the unusual decay pattern of the N(1535) resonance. Evidence supporting this picture from available BES data on J/psi decays is pointed out.
