| Abstract: | In this paper, Powell's optimizing methed is used to determine the particle size distribution in the laser diffraction particle sizer. Numerical calculation and practical test for standard particle lalex demonstrate, this method can obviously improve calculating accuracy of the particle sizer and problem that calculating results vary with initial value of two-parameter models can be effectively solved This method is very suitable to the calculation of the dependent model. |
