摘要：

From all the theoretical small-angle X-ray scattering (SAXS) curves of compact (nonparticulate) systems elaborated systematically by Porod [2], we give a theoretical analysis of only one scattering curve, the corresponding correlation function of which is an exponential distribution. To obtain a correct as well as an easier determination of the zero-intensity I0 and the correlation length l(c) than with the procedure usual up to now (analysis of the plot I(s)- 1/n vs. s2 with n = 2 or 3/2) the classical SAXS-parameters of particle scattering will be involved in the evaluation. In this way the results get also a more useful conception for a practical application.
