摘要：

尽管基于有效场论在理解远距离NN相互作用方面取得了进展，但对短程NN相互作用动力学的理解仍然像以往一样难以捉摸。短程相互作用最吸引人的性质之一是它的排斥性质，这是强相互作用物质稳定的原因。在这种情况下，相关的距离$\le 0.5$ fm是这样的，人们期望夸克-胶子自由度的开始，相互作用由QCD动力学主导。我们回顾了近距离NN相互作用的QCD动力学的理解现状，突出的问题，并概述了硬NN过程的QCD描述的理论基础。我们提出的例子，如何研究的硬弹性NN相互作用可以揭示的对称结构的价夸克分量的核子波函数和pQCD制度的发病与发病的颜色透明现象在硬$pp$散射在核介质中。讨论表明，新的实验设备可以帮助推进知识的QCD性质的核力在短距离。

Despite the progress made in understanding the NN interactions at long distances based on effective field theories, the understanding of the dynamics of short range NN interactions remains as elusive as ever. One of the most fascinating properties of short range interaction is its repulsive nature which is responsible for the stability of strongly interacting matter. The relevant distances, $\le 0.5$ fm, in this case are such that one expects the onset of quark-gluon degrees of freedom with interaction being dominated by QCD dynamics. We review the current status of the understanding of the QCD dynamics of NN interactions at short distances, highlight outstanding questions and outline the theoretical foundation of QCD description of hard NN processes. We present examples of how the study of the hard elastic NN interaction can reveal the symmetry structure of valence quark component of the nucleon wave function and how the onset of pQCD regime is correlated with the onset of color transparency phenomena in hard $pp$ scattering in the nuclear medium. The discussions show how the new experimental facilities can help to advance the knowledge about the QCD nature of nuclear forces at short distances.
