摘要

本文提出了一种稳健的一维小角度散射（SAS）强度剖面去噪方法。使用中心矩展开技术，以无模型的方式实现了SAS强度剖面的涂抹，消除了在去纹理过程中对假定输入的需要。这种创新的方法能够对SAS数据进行数据分析，而无需将分辨率与结构模型进行卷积，从而有助于直接从散射模型中更快地实现和性能拟合函数。

Desmearing small-angle scattering data by central moment expansions

This article proposes a robust method for desmearing 1D small-angle scattering (SAS) intensity profiles. Using the central-moment-expansion technique, smearing in SAS intensity profiles is achieved in a model-free manner, eliminating the need for presumptive input during the desmearing. This innovative approach enables data analysis of SAS data without the resolution being convoluted with the structural model, thereby facilitating faster implementation and performance of fitting functions directly from the scattering models.

期刊介绍： Many research topics in condensed matter research, materials science and the life sciences make use of crystallographic methods to study crystalline and non-crystalline matter with neutrons, X-rays and electrons. Articles published in the Journal of Applied Crystallography focus on these methods and their use in identifying structural and diffusion-controlled phase transformations, structure-property relationships, structural changes of defects, interfaces and surfaces, etc. Developments of instrumentation and crystallographic apparatus, theory and interpretation, numerical analysis and other related subjects are also covered. The journal is the primary place where crystallographic computer program information is published.
