目标。我们分析了一组独特的突出SOHO/SUMER莱曼光谱，通过比较它与合成光谱获得的二维多线程的突出精细结构模型。方法.我们采用了一种新的统计方法来分析观察到的和合成的莱曼光谱。我们比较了使用一组四个统计标准的观测和合成的莱曼光谱的线属性的统计分布。结果我们证明了观测到的莱曼光谱和通过建模得到的合成光谱之间非常好的协议。结论.我们的一套统计标准是非常适合于日珥莱曼光谱的分析，因为它的敏感性，一些不同的参数，在日珥精细结构的条件。
Aims. We analyse a unique set of prominence SOHO/SUMER Lyman spectra by comparing it with synthetic spectra obtained by 2D multi-thread prominence fine-structure models. Methods. We employed a novel statistical approach to the analysis of the observed and synthetic Lyman spectra. We compared the statistical distributions of the line properties of the observed and synthetic Lyman spectra using a set of four statistical criteria. Results. We demonstrate the very good agreement between the observed Lyman spectra and synthetic spectra obtained by modelling. Conclusions. Our set of statistical criteria is well-suited to analyses of the prominence Lyman spectra because of its sensitivity to a number of different parameters governing the conditions in the prominence fine structures.
