摘要：

The structural relaxation behaviour of a maltose glass was investigated by differential scanning calorimetry. The ageing of the material, on storage below the calorimetric glass-transition temperature, T-g, was followed, as a function of time, through the measurement of the enthalpy recovered on reheating. The observed relaxation behaviour was well described by the Tool-Narayanaswamy method, which included the effect of non-exponentiality and non-linearity on the observed behaviour.
