文摘The glass transition process of argon is studied by molecular dynamics simulations with Lennard-Jones potential. The cage effect appears at about 24K. The Lindemann length of argon is found to be 0.55A. Two relaxation processes are clearly observed near the glass transition temperature, which is in agreement with the mode-coupling theory.
