| Abstract: | The small-angle X-ray scattering(SAXS) technique is one of chief tools to study structures of macromolecules and meso-structures.As users of synchrotron radiation small angle X-ray scattering experimental station are increasing rapidly,it is necessary that data processing techniques are provided with them.Some data processing techniques are discussed.It includes the method to become greater data amount of lower angle region and the data must be extrapolated to hole special for the data from experiment,a sample is analyzed. |
