三、固体表面的组成和平衡分凝固体表面的组成对其许多物理和化学性质都往往起决定性作用。例如,催化剂表面的催化活性,合金表面的摩擦磨损,以及金属表面的氧化、腐蚀等等,都和固体表面的组成密切相关。因此测定固体表面的组成,研究表面组成与其各种性质之间的联系,具有十分重要的意义。近代表面物理研究建立了许多取得表面组成信息的实验方法,其中常用的是XPS,AES,SIMS。从已有的各种实验结果,已经清楚知道固体表面的组成与其体组成间一
Third, the solid surface composition and balance The composition of the surface of the solidification of many of its physical and chemical properties are often played a decisive role. For example, the catalyst surface catalytic activity, the alloy surface friction and wear, as well as the metal surface oxidation, corrosion, etc., are closely related to the solid surface composition. Therefore, the determination of the solid surface composition, the study of the relationship between the surface composition and its various properties, is of great significance. Modern surface physics research has established many experimental methods to obtain the surface composition information, which commonly used is XPS, AES, SIMS. From the various experimental results that have been made, it is well known that the composition of a solid surface and its body composition
