%X The dispersion of particles in a mixing layer is investigated by Laser Dopper Anemometer(LDA) and flow visualization. Experimental data are analyzed. The results indicate that the dispersion of particles strongly depends on the Stokes number. It is found that the particles with smaller Stokes number move along the streamline of eddy structures, and the degree of particle dispersion increases with the increasing of Stokes number, and the influence of particles on the fluctuation of flow field is weakened with the increasing of inertia.
