摘要
We present a new correlation function in the form of y(r) = r((Df-D)) exp(-r/a(0))cos(br) to describe the essential features of aggregate structure. The scattered intensity distribution corresponding to this correlation function was obtained. Compared with existing models, the new scattering formula can predict a scattering peak in a finite wavevector and control the scattered intensity decay in larger wave vectors. The experimental scattering patterns obtained from polydimethylsiloxane/paraffin liquid mixtures were tested well by the new model. (C) 1996 American Institute of Physics.
