一、前言现代科学技术的发展,要求了解并研究材料表面薄层的信息。现代表面测试分析技术作为材料测试分析的一个新领域,近年来国外发展得很快。由于材料是通过其表面和外界进行互相作用的,因此对材料表面层进行化学检定与结构测定极为重要,可以更好地理解材料的腐蚀、吸附、污染、扩散、偏析、断裂和破坏等一系列问题。 I. Introduction The development of modern science and technology requires understanding and studying the thin layer of information on the surface of the material. As a new field of material testing and analysis, modern surface testing and analysis technology has developed rapidly in recent years. Because materials interact with each other through their surface and outside, it is important to chemically characterize and structure the surface of the material to provide a better understanding of the range of material corrosion, adsorption, contamination, diffusion, segregation, fracture and destruction problem.
