cze	Kinetic Phenomena in Non-crystalline Materials Studied by Thermal Analysis	The structural relaxation and viscosity behavior of Ge38S62 glass has been studied by thermomechanical analysis. The relaxation response to any thermal history is well described by the Tool-Naraynaswamy-Moynihan model. The apparent activation energy of structural relaxation is very close to the activation energy of viscous flow (Eç = 478?12 kJ mol-1). However, the activation energy of crystal growth obtained by optical microscopy is about one half of this value.	xxxx
