我们回顾了一种强大的正则化方法，称为CONTIN，用于从动态光散射数据中获得胶体悬浮液的尺寸分布。结果表明，该方法与选择最优正则化参数的l曲线准则相结合，正确地描述了用小角中子散射独立表征的微凝胶悬浮液的平均粒径和粒径分布。相比之下，我们发现当使用默认正则化过程时，通过“拒绝概率”方法选择正则化器，结果并不令人满意。(C) 2015 AIP出版有限责任公司
We review a powerful regularization method, known as CONTIN, for obtaining the size distribution of colloidal suspensions from dynamic light scattering data. We show that together with the so-called L-curve criterion for selecting the optimal regularization parameter, the method correctly describes the average size and size distribution of microgel suspensions independently characterized using small-angle neutron scattering. In contrast, we find that when using the default regularization process, where the regularizer is selected via the "probability to reject" method, the results are not as satisfactory.
