The python processing result of this sample is shown in the figure (droplets are marked by green circles), the number of droplets is 155, and the average area is 8.86μm². Since the droplets in this sample were irregular in shape, this project only used the droplet area to indicates its size. Most of the spot areas in the detection area were concentrated in 0.13μm²-20.13μm², accounting for 92.90%, which also verified the research of C.E.Ejim et al. , that the size of the atomized particles would vary with the surface tension or viscosity of the solution.
