柱形颗粒群直径分布的激光衍射测量技术

The Approach of the Laser Diffraction Measurement for the long cylindrical particle diameter distribution

提出了用激光衍射功率谱方法测量柱形颗粒群直径分布的技术方法。解决了长颗粒随机排列时的功率谱探测、及数据快速优化方法等技术难题。此技术已成功地应用于由羊毛和化纤裁截成的柱形颗粒群直径分布的测量，实现结果证明了此技术的可行性和实用性。

A new approach to measure the long cylindrical particle by using the laser diffraction power spectrum method is presented in this paper in detail. Technologic questions such as the optical power detection of the arrangement long particle and the fast optimization have been solved This approach has been applied successfully to measure the long particles from wool and chemical fiber that have been cutto a little pieces. The measurement results have shown that this approach is feasibility and practicable.
