摘　　要：从六夸克体系p s方程出发,导出了2个核子之间的相对运动方程———共振群方程,研究了在近程范围内夸克胶子交换势对核力的贡献,并结合中长程范围单π双π介子交换对核力的影响,从而全面研究了核力的性质,给出核子-核子相互作用的解析表达式.The equation of relative motion between two nuclei,i.e. resonance group equation,is derived from the p-s equation of six quarks system.And by resonance group method and integral transformation,the analytic representation of quark-gluon exchang potential was got.By further considering the short range part of the contribution of quark-gluon exchange potential and the intermediate-long range part of the effects of one-pion and two-pion exchange to nuclear force,the analytic representation of N-N effective potential was given,thus the nature of the nuclear force is studied all-sidedly .
