| Abstract: | By using a linear CCD as the detector module,a measuring system for particle size distribution was established by laser diffraction.Based on numerical computation,the two problems in Chin-Shifrin integration particle size inversion algorithm:the divergence of inversion in a small particle size and its false peaks,were analyzed and the causes of these phenomena were explained.Then,the modification of the integration formula was proposed to resolve the divergence problem.Aiming at the particular application o... |
