文摘By employing the parametrization form of the nucleon spin structure function in the resonance region,which includes the contributions of the resonance peaks and of nonresonance background, we study Bloom-Gilman quark-hadron duality of g1 both in the inelastic resonance region and elastic one.

文摘三质子旋转结构功能 g (1 ) 的夸克强子两重性, g (2 ) andg (T) 同时被讨论。这被发现夸克强子两重性 ofg (1 ) 的发作(p) , g (2 )(p) 和 g (T)(p) 是类似的,他们被期望在大约 Q (2 ) 类似的 to2GeV (2 ) 。另外,我们的结果证明有弹性的山峰显著地打破本地 quark-hadronduality。
