摘要：
In the present article we use a method for isoconversional analysis which has been derived from the classical nucleation theory, Further on it was applied as an approach to evaluation of non-isothermal data, obtained with a cooling-heating microscopic stage. Basic kinetic parameters of the process of nucleation and overall crystallization in undercooled water and aqueous solutions were determined. The reverse process - melting was also considered. Gauss probability distribution was used to fit experimental data and to obtain the distribution function of the crystallization event.
