Figure 7. Time evolution of the order parameter for the density of the heavier particles being ${\rho }_{h}=16.0\,{\rm{g}}\,{\mathrm{cm}}^{-3}$ (circles), $6.0\,{\rm{g}}\,{\mathrm{cm}}^{-3}$ (diamonds) and $4.0\,{\rm{g}}\,{\mathrm{cm}}^{-3}$ (triangles), respectively. The density of the lighter particles is fixed at ${\rho }_{l}=2.0\,{\rm{g}}\,{\mathrm{cm}}^{-3}$ in this figure. The open and closed symbols are used in the same way as that in figure 6.
