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π,双π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. 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.
