摘要
介绍脱硫塔内离心喷雾雾场中雾粒沿塔体分布的测试结果，指出粒子的运动轨迹测试是一个国际上共同关心的问题。用双曝光散斑图的分析方法来分析微粒运动，其中介绍了双曝光散斑图的分析原理以及如何用全息透镜阵列来分析颗粒在平面内的移动，从垂直两平面获取微粒运动的双曝光图，通过光学并行处理和图象的分析得到颗粒空间运动轨迹的可能性。文中还讨论了一些试验结果和尚待研究的问题。
Some measuring results about droplets distribution of atomizing field in the desulfurisation tower are introduced and then present a popularly interesting question about measuring particles moving trace at home and abroad in this paper. Questions are discussed as follows:A method of analyzing particles movement with double exposure specklegram (DES),analyzing pinciple of DES, how to analyze particles movement by the hololens array, how to make DES of particles movement in two perpendicular planes and possibility of measuring particles apace move trace with optical parallel pocess and image analysis.
