| Abstract: | By means of resistance measurement and microcomputer data
processing under the pressure of 0-2GPa,high pressure container
with microcomputer data acquisition system,program-controlled
heating as well as automatically regulating temperature,the inf-
luence of pressure on the dynamic parameters,namely,crystallization
activation energy,crystall ization rate and so on,as well as inter-
relation among parameters have been approached.In addition,the
limitation of Kissinger formula is pointed out when the relative
effectiveness of Matasita formula is related in the analysis of
erystallization dynamics. |
