Figure 4. Time evolution of the order parameter for smaller density difference between the lighter (${\rho }_{l}=1.0\,{\rm{g}}\,{\mathrm{cm}}^{-3}$) and heavier (${\rho }_{h}=3.0\,{\rm{g}}\,{\mathrm{cm}}^{-3}$) particles at a series of vibration amplitude. The symbols are used in the same way as that in figure 3.
