| Abstract: | Based on the extinction theory in measuring particles systematically, using independent algorithm, an optimization method was generated based on Powell algorithm to simulate the particle size distribution. Also the mean particle size was obtained by three-wavelength theory. Numerical simulation was consistent with hypotheses in advance. The results prove that the algorithm is exact and reliable. |
