    "abstract": "The average scattered intensity is determined by the optical characteristics\nof particles in dispersion. The normalized time auto-correlation function of\nthe scattered light intensity $g^{(2)}(\\tau) $ includes both the optical and\nhydrodynamic information of particles. From the different characteristics of\nparticles, the particle sizes can be obtained. In this paper, three sizes: the\nstatic radius $R_{s}$, the hydrodynamic radius $R_{h}$ and the apparent\nhydrodynamic radius $R_{h,app}$ are discussed using dilute water dispersions of\nhomogenous spherical particles poly($N$-isopropylacrylamide) microgels, with a\nsimple assumption that the hydrodynamic radius is in proportion to the static\nradius, when Rayleigh-Gans-Debye approximation is valid. Our results show that\nthe expected values of the normalized time auto-correlation function of the\nscattered light intensity are consistent with the experimental data very well\nand the difference between the static radius and the apparent hydrodynamic\nradius is large and the difference between the hydrodynamic radius and the\napparent hydrodynamic radius is influenced by the particle size distribution.",
