The results show that the streamwise mean velocity profile of particles takes on a Gauss distribution, and the lateral mean velocity profiles assumes a Sinedistribution.
结果显示，颗粒的流向平均速度剖面呈高斯分布，而横向平均速度剖面则呈正弦分布。

In chapter 4, According to the theory of scalar diffraction, firstly, the equipollence of spatial distribution of the plane-wave interferential field and parallel projective sine grating is discussed.
