摘　　要：简要评述了中高能核物理中核子-核子(NN)碰撞的国际研究现状,期望对兰州重离子加速器冷却存储环(HIRFL-CSR)的物理工作有益。文中主要涉及近年来短程核力研究进展与存在的困难,及与STAR和PHENIX高能重离子实验新进展相关的若干NN两体碰撞基本问题等,特别关注奇异性产生与重味产生方面的NN碰撞物理,以便更好地认识中高能NN碰撞研究的重要性。Some topics on nucleon-nucleon（NN） collisions in medium and high-energy nuclear physics are reviewed with emphasis on those which are expected to be relevant at the HIRFL-CSR Facility.It is mainly concerned with the description of short-range NN nuclear force,the recent results from STAR and PHENIX experiments in relativistic collisions of nuclei from each other,addressing questions about the role of NN collisions at high-energy,especially for strangeness production and heavy flavor production.Recent progress and some unresolved issues are also concerned.We expect that the results of the present work will lead to a better understanding on the importance of NN collisions at medium-and high-energy.
