The negative density perturbation of collisionles particles grows quickly to the void and surrounding ridge. Meanwhile, the shell-crossing occurs. The nucleonic matter, which is set uniformly at the decoupling epoch, is enforced to concentrate into the ridge by the gravitational force at this shell-crossing epoch. At the same time, the temperature of nucleonic matter increases rapidly due to the dissipation of kinetic energy by the pressure force. The dependence of results upon the amplitude of the initial density perturbation is made clear. If the galaxies were formed after the shell-crossing, the initial amplitude of density perturbation of collisionless particles must be higher than 0.03 in the Einstein-de Sitter universe. Through the analysis of gravitational instability of ridges, a possible scenario for the formation of the large-scale structure of the universe within the adiabatic theory is presented.
