摘要：

A dynamical valence and sea quark mixing model is shown to fit the baryon ground state properties as well as the spin content of the nucleon. The relativistic correction and the q(3) <----><q(3)q(q)over bar> transition terms induced by the quark axial vector current <(psi)over bar gamma gamma(5) psi> in this model space is responsible for the quark spin reduction.
