摘要
本文对三维分布颗粒群的激光粒度分析中的重衍射作了较为详细的理论分析,提出了最佳衍射浓度的概念。对水泥气固两相流的测试结果证实了理论的正确性。为提高三维分布颗粒群的激光粒度分析精度;抑制重衍射噪声;提供了理论依据和一种行之有效的方法。
In the paper a key problem in Laser particle size anatysis for particle growp dispersed in
3-Dspace.the N times diffrection hes been treatad.A new concept, the optium diffrection density has also been put
out.The measuriug results to cement airsold diphase flow verified the nicw aloue.
This paher provided a feasible methord in Laser particle size analysis to 3-D pasticle growop.
