On the basis of population balance, crystallization kinetics and mass balance equations, the mathematical model for dilution crystallization of SDP was established. Process simulation was developed by Ronge-Kutta-Gill algorithm and FORTRAN language.

• 依据粒数衡算原理，结合结晶动力学方程、质量衡算方程建立了溶析结晶过程数学模型，并通过Ronge-Kutta-Gill算法和FORTRAN语言实现过程模拟。
