| Abstract: | Dynamic light scattering signals from particles exhibit fractal characters,and can be expressed by fractal dimensions.The fluctuation and the application of Variation in the computation of the fractal dimension of dynamic light scattering is analyzed,the fractal dimensions of the dynamic light scattering from particles with diameters 60nm,90nm,200nm,300nm,450nm under different temperatures are obtained,and the Variation is compared with the Box dimension. |
