一种基于SAXS技术的二维散射谱计算方法及系统
摘要：
本发明涉及一种基于SAXS技术的二维散射谱计算方法，该方法包括以下步骤：象限选择步骤：利用SAXS本身的特性进行简化，基于SAXS散射图谱的对称性，选择其中一个象限进行匹配；提取特征点的步骤：提取该象限内SAXS散射图谱的特征点；筛选散射图谱的步骤：根据提取的特征点筛选该象限内的SAXS散射图谱；筛选全散射图谱的步骤：基于SAXS散射图谱的对称性，由该象限内的SAXS散射图谱生成整个SAXS散射图谱。本发明还提出一种基于SAXS技术的二维散射谱计算系统。本发明根据SAXS本身的特性只需对一个象限进行匹配，在保留足够信息量的同时减少计算拟合的数据量，有效提高二维散射图谱的计算时间。
摘要（英）：

The invention relates to a two-dimensional scattering spectrum calculation method based on SAXS technology. The method includes: a quadrant selection step: utilizing the characteristics of SAXS itselfto perform simplification, and based on the symmetry of an SAXS scattering spectrum, selecting one quadrant therefrom for matching; a characteristic point extraction step: extracting the characteristic point of the SAXS scattering spectrum within the quadrant; a scattering spectrum screening step: screening the SAXS scattering spectrum within the quadrant according to the extracted characteristicpoint; and a total scattering spectrum screening step: based on the symmetry of the SAXS scattering spectrum, generating a whole SAXS scattering spectrum from the SAXS scattering spectrum within thequadrant. The invention also presents a two-dimensional scattering spectrum computing system based on SAXS technology. According to the characteristics of SAXS itself, the method and system provided by the invention only need to match one quadrant, reduce the data size of computation fitting while reserving enough information amount, and effectively improve the computation time of two-dimensionalscattering spectrum.
