摘要
本文讨论了双层颗粒群产生的二次衍射,并给出了二次衍射复场分布的表达式,同时讨论了二次衍射与颗粒浓度之间的关系,找到了抑制二次衍射的最佳浓度。本文结论对于提高激光粒度仪的测量准确度具有重要意义。
In this paper, the re-diffraction made from the double layers partical group has been discussed and the express ion of complex field of rediffraction has been given The relationship between the re-diffraction and the partical density has been discussed at the same time, and the optimum density which can control the re-diffraction has been found out. The result is of great significance for raising the measure accuracy of laser partical sizer
