光散射法测试粒径的一种优化反演组合算法

在目前常用的激光粒度仪反演算方法的优点和缺点基础上,为了实现各种方法的稳定性与准确性的统一,提出一种基于退火演化算法和遗传算法组合的随机反演方法,该方法具有更强的全局收敛性,也具有对粒径分布形状不敏感、抗噪声能力强等优点。该算法能对具有单峰及双峰分布形式的颗粒尺寸进行精确求解,并获得合理的颗粒粒径分布结果。

An inverse of combinatorial algorithm for measuring particle size by light scattering method

Based on the existing inversion methods, in order to satisfy the stability and accuracy in the applications of different methods, one kind of particle size distributed stochastic inversion algorithm is proposed. The algorithm combines the advantage of the annealing evolution algorithm and the genetic algorithm and has the stronger global convergence. The algorithm has ability to distinguish the distribution of single and the twin peaks accurate, and doesn't need any prior information based on this inversion...
