一、引言 表面科学是六十年代末发展起来的一门新型学科,虽然有关许多表面物理现象早在本世纪二、三十年代已发现,但只有在最近十几年来,由于真空技术,电子仪器及计算机技术的迅猛发展,才为表面科学的建立和发展奠定了比较扎实的基础。现在这门年轻的科学显示了其强大的生命力.几乎渗透到各行各业,主要是它能够解决国民经济工程技术中许多表面现象的实际问题。它不仅是一门理
I. INTRODUCTION Surface science is a new discipline developed in the late 1960s. Although many surface physics phenomena have been discovered in the 1920s and 1930s, only in the last decade or so have vacuum technologies, electronic instruments And the rapid development of computer technology have laid a solid foundation for the establishment and development of surface science. Now this young science shows its great vitality, which has infiltrated almost all walks of life mainly due to the fact that it can solve many of the apparent phenomena in the national economy in engineering. It is not just a reason
