Abstract：
The effects of quark-antiquark pairs of quark sea and hybrid states of gluonquark are considered in the proton wave function. The spin-dependent structures of the proton,such as magnetic moment, axial-vector coupling constant GA/GV, and integrated structure functions g1p or g1n are calculated with some improvements using the wave function.
