现代数学方法的小角散射数据处理和解释的问题的应用被认为是。 特殊的可能性，在数据处理，即同时处理不同的实验条件下获得的数据集和联合数据处理的双分散实验，提出。 这些方法是基于正则化技术的间接方法的进一步发展[Svergun，Semenyuk和Feigin（1988）。 Acta Cryst.A44，244 - 250]。 基于多极展开理论的形状确定技术的最新改进[Stuhrmann（1970）. z.（法兰克福美因河畔），72，177 - 184，185 - 198]中描述。 提出了一种利用球谐函数技术确定复杂粒子中亚基位置和相互取向的新方法。
Applications of modern mathematical methods to the problems of small-angle scattering data treatment and interpretation are considered. Special possibilities in data treatment, namely simultaneous treatment of data sets obtained with different experimental conditions and joint data processing for the anomalous-dispersion experiments, are presented. The methods are further developments of the indirect method based on the regularization technique [Svergun, Semenyuk & Feigin (1988). Acta Cryst. A44, 244-250]. Recent improvements in the shape-determination technique based on the multipole expansion theory [Stuhrmann (1970). Z. Phys. Chem. (Frankfurt am Main), 72, 177-184, 185-198] are described. A new method is proposed for the determination of positioning and mutual orientation of subunits in complex particles using the spherical harmonics technique.
