Correlation between the crystal size and crystal growth rate of KDP and Rochelle salt crystals

It is shown that the dependence of the crystal growth rate on the initial c rystal size is linear, or probably, more complex, but there is no reason fo r using some complex functions for describing the mentioned dependence, as many authors do. Correlation between the initial crystal size and the cryst al growth rate is positive, i.e, higher growth rate of the crystals corresp onds to the larger initial crystal size.
