摘　　要：溶解度和过饱和度是溶液结晶动力学的重要参数。建立了溶解度在线测量的实验装置 ,以KNO3-H2 O为模型体系 ,得到了结晶过程的实时溶解度和过饱和度 。The concentration and supersaturation are considered as the important parameters for the kinetics of crystallization. An experimental apparatus was setup in our lab for on-line measurement of concentration, and KNO 3-H 2O system was also tested. The results showed that the apparatus is available for our further investigation due to its enough precision and good repeatability.
