| Abstract: | Moving velocity,size and light scattering property of particle can be simultaneously measured by laser phase Doppler anemometry.On the basis of laser phase Doppler anemometry technology,the size distribution of bacteria in polluted water and its light scattering property are investigated.The sorting and detection of the bacterial community in the polluted water sample is carried out by means of fuzzy mode recognition technique. |
