Thanks again for your attention, According to the principle of SAXS, the scale of defects is correlated with the q range, so the increase in scattering intensity without the change of q range can be explained into the number of pores increasing, while the existing pores increasing in volume would result into an change of q to low range.
Review of the manuscript Investigation on the Evolution of Nano-scale Defects of CL-20 Crystals under Thermal Treatment by Wide/Small-Angle X-ray Scattering, Haobin Zhang, Hongfan Wang … The manuscript is devoted to research on the phase transformations of CL-20 at various temperatures.
