摘要：
We have calculated delta g/g in the nucleon at all measured kinematics. The smallness of delta g/g in the measured kinematics should not be interpreted as the the gluon contribution to the nucleon spin is small. In fact the first moment of gluon polarization in the nucleon, Delta g(Q(2)) can be sizable.
