我们提出了一种利用小角散射技术定量评估非球形粒子场致排列的策略。从各向异性散射强度出发，采用实球谐展开法确定了取向分布函数（ODF）。我们开发的方法简单且具有分析性，在数据分析中不需要假设ODF作为输入。对准刚性棒的模型研究证明了这种方法的有效性，以促进具有首选取向状态的材料的定量结构表征。
We present a strategy for quantitatively evaluating the field-induced alignment of nonspherical particles using small-angle scattering techniques. The orientational distribution function (ODF) is determined from the anisotropic scattering intensity via the scheme of real spherical harmonic expansion. Our developed approach is simple and analytical and does not require a presumptive hypothesis of the ODF as an input in data analysis. A model study of aligned rigid rods demonstrates the validity of this proposed approach to facilitate the quantitative structural characterization of materials with preferred orientational states.
