将讨论用于岩心杆光谱峰形分析的几种方法，以对浴峰形状和背景轮廓进行建模。提出了一个通用程序，它结合了峰形状和背景的充分建模的选项、用于迭代非线性参数估计过程的成功数值算法的实现以及灵活且方便的数据处理。该程序代码的性能通过拟合综合模型谱来证明。还提供了一个分析复杂实验光谱的示例。使用所提供的软件成功分析了从 MET 处理的黄铁矿表面记录的 S 2p 光谱，并发现其特征在于五种不同的 S 2p 贡献。
Several approaches used in the peak shape analysis of core lever spectra for the purpose of modelling of bath peak shapes and background profiles will be discussed. A universal program is presented, which combines options for adequate modelling of the peak shapes and background, implementation of a successful numerical algorithm For an iterative non-linear parameter estimation procedure, and a flexible as well as convenient data handling. The performance of this program code is demonstrated by fitting a Synthesized model spectrum. An example for analysis of a complex experimental spectrum is presented, too. An S 2p spectrum recorded from a MET-treated pyrite surface is successfully analyzed using the presented software and is found to be characterized by five different S 2p contributions.
