摘　　要：Glass is a nonequilibrium state that continually relaxes toward a metastable equilibrium state by structural rearrangements.What is mysterious is that its past state is always memorized,viz.,showing memory effect.Glass exhibits disordered structure and anomalous atomic vibration as compared to ordered crystals,and this anomaly is termed as a boson peak.These two features,both are central to the understanding of glass,are generally investigated separately.Glass is a nonequilibrium state that continually relaxes toward a metastable equilibrium state by structural rearrangements.
