摘要
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。
Quark-hadron duality of three proton spin structure functions g1, g2 and gT are discussed simultaneously. It is found that the onsets of the quark-hadron dualities of g1^p, g2^p and gT^p. are similar and they are expected to be at about Q2～2 GeV2. In addition, our results show that the elastic peak remarkably breaks local quark-hadron duality.
