Abstract：
We propose a new baryon wave function which is constructed from the three quark configuration with SU(6) symmetry together with the configuration of the accompanying excitation of sea quark and valence quark. Using this wave function, the calculated results of GA/GV, μp/μn. and the contribution of quark spin to the proton spin are in fair agreement with the experimental data.
