1.绪言研究金属的腐蚀现象,不仅可以查明其原因和寻求对策,而且对于新技术的发展来说,也是不可缺少的。尤其是在节约资源和能源方面,就更显得重要了。分析技术能为金属的腐蚀、防蚀研究提供宝贵的资料,其中的表面分析技术近年来得到了特别惊人的发展。过去,人们在腐蚀研究中曾用过电化学法、椭圆对称法等。近 1. INTRODUCTION Studying the phenomenon of metal corrosion can not only identify its causes and find solutions, but also become indispensable for the development of new technologies. Especially in terms of saving resources and energy, it even becomes more important. Analytical techniques can provide valuable information for metal corrosion and anticorrosive research, and the surface analysis technology has been particularly and surprisingly developed in recent years. In the past, people used electrochemical methods in the corrosion study, elliptical symmetry method. near
