摘要
运用弥散粒子群Mie光散射理论建立了粒子测试的光学计算模型及多变量单纯型优化方法。研制出以线阵CCD光电探测阵列为接收器的激光粒度仪样机,适于0.31～168μm固体粉末或混浊液中悬浮粒子的粒度分布测量。与其它方法的测量结果对比分析,证明了设计原则的正确和样机的研制成功。
The calculation model of particle sizing and simplex optimization method with many variables are established through theoretical deduction and investigation of Mie scattering by polydisperse particles. The prototype of a Laser Particle Size Analyser with linear CCD detector array has been developed. It is applicable to measuring particle size distribution of solid powder or liquid suspension in size range of 0.31～168μm. Comparisons with the results of measurements obtained by other instruments show that the design of this analyser is correct and the instrument is successful.
