摘要：

A simple method ensuring a high accuracy of determination of the mass transfer coefficients, kd, and the surface reaction constants, kr, during crystallization has been elaboarated. The relative standard deviations between the crystal growth rates calculated from the equation Δc = Rg/kd + (Rg/kr)1/r and those experimentally obtained and described by a relationship Rg = kg(Δc)g do not exceed 1.5%. The values of kd and kr estimated from the proposed integral method are close to those directly determined from the measurements of the rates of crystal dissolution and growth. © 1990.
