光全散射法颗粒测量中的一种自适应非独立模式算法

A New Method to Determine Automatically the Measurable Range of the Light Extinction Particle Sizing Technigue

光全散射颗粒测量法中需求解第一类Ｆｒｅｄｈｏｌｍ积分方程。在不知道被测颗粒的尺寸范围的情况下如何确定积分方程的上下限、即测量范围，迄今仍是个问题。本文针对此问题提出了一种自适应非独立模式算法。该算法可根据双参数颗粒分布函数的分布参数Ｋ自动确定积分的上下限．数值模拟和实验都证实了此算法。

In the light extinction particle sizing technique, Fredholm integral equation of the first kind has to be solved. How to determine the upper and lower limits of the integral equation or the measurable range for measurementsof particles with unknown range of sizes remains unsolved. This paper presents a new algorithm-a self adaptive algorithm of the dependent model,which will determine the upper and lowerlimits of the integral equation automatically interms of the value of k,two-particle distribution function. Numerical simulation and experiments were carried outto confirm this algorithm.
