摘要
光散射法粒度测试涉及到粒度反演技术.随着反演粒级数的增加,通常的粒度反演法将出现严重的振荡.文章将Chahine迭代算法与平滑滤波技术相结合解决了高反演粒级数下数值解的振荡,在不改变激光粒度仪的原有结构情况下,就可明显提高仪器的精度和分辨能力.
The particle size inversion algorithm plays an important role in the laser size.The higher the degree of the inversion size is,the more instable the inversion results will be.The Chahine iterative algorithm together with smooth filter technology is used to overcome the instability.The calculated results show that the smooth Chahine algorithm improves the instrument s precision and its resolving power remarkably without changing the original physical configuration of the instrument.
