1.固体表面分析的重要性固体表面分析方法和仪器是表面物理研究的重要内容之一。一些表面现象和效应的研究为表面分析方法和仪器奠定了基础,而表面物理研究取得的进展和成就又为分析方法和仪器的发展和广泛应用紧密相联。表面物理是一门实验和理论都在发展的新兴学科。表面是指固体最外面的几个单原子层(大约为5～20埃),以及表面可能存在的吸附层。表面有许多与体内不尽相同的特殊问题:(1)许多物理和化学过程(如摩擦、腐蚀、催化、电子发射等)发生在表面或首先发生在表面;(2)表面的组份与体内不同(发生了
1. The importance of solid surface analysis Solid surface analysis methods and instruments is one of the important aspects of surface physics. Some studies of surface phenomena and effects have laid the foundation for surface analysis methods and instruments. The progress and achievements made in surface physics research are closely linked with the development of analytical methods and instruments and their wide application. Surface physics is a new discipline in which both experiment and theory are developing. Surface refers to the outermost solid several monatomic layers (about 5 to 20 angstroms), and the surface may exist adsorption layer. There are many specific problems with the surface that are not the same in the body: (1) many physical and chemical processes (such as friction, corrosion, catalysis, electron emission, etc.) occur on the surface or first on the surface; (2) Different (happened
