标题： Asymptotic Freedom

摘要： 我讨论如何用基本的物理概念来理解QCD中的渐近自由这一基本现象。 同样地，我讨论如何长期预测的“质子的胶子化”现象——最近在HERA上得到了惊人的证实——是渐近自由物理的一种直接表现。 我回顾了QCD中渐近自由在基础物理中的更广泛意义：一方面，它指导实验的解释甚至现在的设计，另一方面，它使得对统一问题和早期宇宙宇宙学的问题能够进行理性、定量的理论研究。 显示英文摘要

摘要： I discuss how the basic phenomenon of asymptotic freedom in QCD can be understood in elementary physical terms. Similarly, I discuss how the long-predicted phenomenon of ``gluonization of the proton'' -- recently spectacularly confirmed at HERA -- is a rather direct manifestation of the physics of asymptotic freedom. I review the broader significance of asymptotic freedom in QCD in fundamental physics: how on the one hand it guides the interpretation and now even the design of experiments, and how on the other it makes possible a rational, quantitative theoretical approach to problems of unification and early universe cosmology.
