1.前言15年来,表面科学经历了一个飞速发展的时期,很好地体现了库恩(Thomas Kuhn)关于“科学革命”的预言。伴随这次革命,对世界认识的一个根本改变就是两个物质体之间有一个界面存在,也就是存在一个具有一定组分、结构、化学键、电子态、原子动力学的物质态,而不是由两个物体之间过渡所决定的边界。 1. Foreword In the past 15 years, surface science has undergone a period of rapid development, a good illustration of Thomas Kuhn’s prophecy about the “scientific revolution.” With the revolution, a fundamental change to the understanding of the world is that there exists an interface between two material bodies, that is, there exists a material state with certain components, structures, chemical bonds, electronic states and atomic dynamics, not by Border between two objects as determined by the transition.
