On the Transitional Phenomena of Glass

Abstract

A new interpretation on the glassy state, which includes the explanation of the transitional phenomena, is proposed on the basis of the superposition of the two modes of motion, one of which is the network deformation and another is the vibration around the instantaneous configuration of network. To formulate this idea, a new parameter, that is the “network temperature”, is introduced and the thermodynamical treatment is performed, with the independent derivation of the equation of motion. Finally, some experimental data are checked with this theory and its validity is discussed.
