摘要：

Based on heat capacity measurements. we propose a simple approach to determine the fictive temperature (T-f) of a hyperquenched glass. The recovered enthalpy of heating is estimated, which equals the released amount of the excess inherent structure energy stored in the glass, The hyperquenching is reached by means of the fiber spinning. We analyze relationships between the released enthalpy. changes in the internal energy, and changes in the configurational entropy. (C) 2002 Published by Elsevier Science B.V.
