摘要The newest progress on the study of the strangeness in the proton and in the lowest negative parity nucleon excited state N*(1535) is reviewed. Implications on the internal quark structure of the proton, N*(1535) and other baryons are discussed. The diquark cluster picture for the 5-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 longstanding 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 for possible existence of N*(1535)'s 1/2(-) SU(3) nonet partners in this picture is pointed out, and suggestion is made to search for these 1/2(-) hyperon excited states under the well known Sigma*(1385), Lambda*(1520) and Xi*(1530) peaks in various reactions.
