摘　　要：通过X射线光电子能谱(XPS)分析手段,对经不同清洗液超声清洗并气枪吹干后的镀锡板样品表面元素组成进行了表征,发现经过这些传统的测试前处理过程,样品表面均会留下一个主要由C、O及可能存在的H为主要成分组成的薄膜。该薄膜在常温下的大气环境中表现稳定,但在轻微加热后可完全脱附。由此总结出对镀锡板样品,使用如下方法,即酒精超声清洗并冷风吹干后,进样到真空室里,等待进行分析前,再将样品微微加热使保护膜脱附,可以得到洁净的待分析表面,满足表面分析的需要。The surface compositions of tinplates cleaned in different cleaning fluids and dried by air gun are analyzed by X-ray photoelectron spectroscopy （XPS）. It is found that a thin film composed of C, O, and possibly H exists on each surface of the samples after these traditional pretreatments. This thin film stays stable at room temperature under atmospheric condition, and it can be totally desorbed after slightly heating. Thus a satisfying pretreatment method for tinplate surface analysis can be ob- tained： ultrasonic and alcohol cleaning is employed before the sample transmission into the vacuum chamber. In order to get a clean surface as analysis requires, the sample is slightly heated just before analysis to lead desorption of the protective thin film.
