[交流] 【求助】求助DLS动态光散射测粒径的问题

大侠们好,最近有篇文章修改意见是关于DLS动态光散射测粒径的,小弟一窍不通,请赐教。
下面图是我的粒径分布图

还有审稿人提的意见,


The results from dynamic light scattering showed two peaks, from 50 to 100 nm, and
then from 120 to 350 nm. I am not sure how the authors derived the spectra, and what
mathematical routine was used to transform the correlation function into distribution
function. It would be great if the authors analyzed data from various scattering angles (as
it was stated that a 12 angle detector system was used. The author should check the q2
dependence (q is the scattering vector) of the relaxation rate, so as to confirm that the
scattering objects are indeed diffusive!

大家觉得应该从哪个角度分析呢?
Ps:DLS measurements were carried out with a Wyatt QELS Technology DAWN HELEOS instrument poised at room temperature by using a 12-angle replaced detector in a scintillation vial and a 50 mW solid-state laser (λ=658.0 nm).

非常感谢!!!中肯意见小弟将倾囊相谢
