中文摘要：

本文介绍我们自己编写的一个小角散射数据分析程序。该程序基于FORTRAN语言，其功能包括：小角散射实验数据的背底扣除，Guinier定律和Porod定理的应用，样品分形特点的分析，粒度分布函数的计算，以及散射强度曲线的检验。通过理论计算的结果与实验结果的比较，还可以进一步得到简单的颗粒形状的信息。

英文摘要：

A program for small-angle X-ray scattering （SAXS） data analysis was written in FORTRAN language based on the raw data format in Beijing Synchrotron Radiation Facility. The first version of this program, SAXS1.0, includes the following functions and characteristics： raw-data pretreatment, background removal, Guinier-plot, Porod-plot log-log plot, particle-size distribution, comparison between calculated and experimental scattering intensifies, etc. Some simple particle-shape information can be derived from the parameters obtained with the code.
