本文从建立椭园衍射模型入手,探讨了球形颗粒与真实颗粒在傅立叶谱上的数量关系,提出了一种傅立叶粒径定义,该定义为激光衍射法测非球形颗粒,提供了一种可行的方法。
Starting with the establishment of an elliptical diffraction model, this paper discusses the quantitative relationship between the spherical particles and the real particles in the Fourier spectrum, and presents a definition of Fourier particle size. This definition defines a non-spherical particle by laser diffraction and provides a feasible method.
