摘要
在激光测粒仪的设计和数据处理过程中,都采用了无因次准则数x=1.357。之后,为了降低激光测粒仪的测量下限,经典的Mie散射理论在激光测粒仪的设计中得到了应用。讨论了在利用Mie光散射理论时,无因次准则数x的取值及其影响因素。
Abstract
The criterion number X which equals 1.357 is adopted in the design and data processing of the laser FD based particle sizes. The classical Mie light scattering theory is used in the design of the laser particle sizers to extend their lower size limit. According to the theory, the criterion number X and the factors influencing X are discussed in detail.
