%X The apparent temperatures on Differential Scanning Calorimeter were calibrated by measuring the melting temperature of In, Zn, Sn and Ph with different heating rates, different crucibles and different sample weights. Based on the calibrated results, the kinetic characteristics of the glass transition for Ni33Zr67, Zr65Al7.5Ni10Cu,,Co2.5,Pt69.0Ni9.6P2104, polyethersulfone and polystyrene were studied. The results show that there is a linear relation ship between the logarithm of heating rates and the glass transition temperatures. It is argued that this linear relationship is not against the Vogel-Fulcher law. According to the measured glass transition temperatures and Vogel-Fulcher law, the ideal glass transition temperature and the activation energy for the glass transition were calculated.
