| 摘 要： | 研究了琥珀酸十八酯（ＯＳＯ）晶体过饱和溶液的成核过程，测量了以诱导期表示的成核速率，讨论了温度、过饱和度和溶剂对成核速率的影响。ＯＳＯ过饱和溶液的成核速率随着温度的升高和过饱和度的增大而增大，溶剂不同其数值也不同，实验结果根据经典成核理论进行了分析。

| Abstract: | The nucleation in supersaturated solutions of dioctadecyl succinate(OSO)crystals has been studied in this paper.Nucleation rates as indicated by induction period are measured.Effects of temperture,supersaturation and solvent on the nucleation rate are discussed.The experiment results are analysed in accordance with classical nucleation theory.The nucleation rate of OSO crystals increases with temperature and supersaturation,and differs in benzene and toluene. |
