| 摘 要： | 计算了核子- 核子散射的总相移, 包括夸克- 胶子交换的总的相移、夸克- 胶子瞬时势的贡献以及单, 双交换提供的总的相移. 相移的计算值与实验结果的比较曲线表明它们是一致的, 同时表明夸克- 胶子交换作用在核子相互作用中起重要作用, 尤其在近程范围内.

| 关 键 词： | 散射相移 夸克-胶子交换 单π交换 双π交换 |

| Abstract: | The total N-N scattering phase-shifts are calculated ,including the total phase-shifts of quark-gluon exchange potential,the phase-shifts of quark-gluon exchange instantaneous potential as well as the total phase-shifts of one-π and two-π exchange potential.The comparison of the calculation of phase-shift with the experimental result shows that they are consistent with each other and that quark-gluon exchange plays an important role in the N-N interaction,expecially in the short range. |

| Keywords: | scattering phase-shifts quark-gluon exchange potential one-pion and two-pion exchange |
