摘要
本文用最优化理论中的Powell直接法求激光粒度仪中的颗粒尺寸分布。数值模拟及对标准颗粒的实测表明,该算法的计算精度高,能较好地解决粒度仪通常存在的计算结果随初始设定值变化的多值性问题。
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.
