英文摘要	介绍了XPS(X-ray photoelectron spectroscopy)谱图中本底产生的机理以及Tougaard法本底扣除原理的简略推导过程,提出了可供编程的约化形式,使用VC语言编写程序试对不同样品(含金属、过渡金属及非金属)的谱图进行本底扣除,并与Shirley法、直线法本底扣除进行准确性的比较,提出了Tougaard方法试用于非金属粉末化合物样品的测试分析结果.; Both the mechanism of the background generated and the derivation process of Tougaard's method used for subtracting background in XPS are elucidated briefly, and the Tougaard's simplest form used for writing the calculation program is presented. To inspect the suitable range to the Tougaard's method, the most of samples, in this research which have not been involved in the measurements by Tougaard are selected, such as PbCl2,TiO2, SnCl2, MoO3, NaCl, NaBr, KI, NaH2PO4, Na2SO4, and SiO2. Of course, in order to compare with the results measured by Tougaard, the pure Au, Ag, Cu and Ni are also selected and measured. The program of Tougaard-like written by ourselves to use the VC language are tried to be applied to subtracting backgrounds of some spectra from fourteen various kinds of sample including metal, transition element and nonmetal. All of results from eighteen typical sets of data are compared successively with those taken from both Shirley's and straight-line's methods (Fig. 3 similar to 5 and Table 2, 3 respectively). The comparisions of deviation of three experimental methods from the theoretical calculations are also made (Fig. 6). Finally, according to our experimental results, it is shown that the Tougaard's method indeed could give out the more accurate peak area measurements in XPS, i.e. possessing the least deviations from the theoretical calculating value in the three methods used for both subtracting background and measuring the peak area not only suitable for both the noble metal and transition metal, but also for the samples of nonmetal and powder compound.; 国家自然科学基金; 国家科技攻关项目; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000175148800008&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 0; 4; 326-331; 18
