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.
