A linearized integral model based on classical nucleation theory is applied in this work to determine the interfacial energy and pre-exponential factor using a linear plot from the cumulative distributions of the metastable zone width (MSZW) data for some systems reported in the literature, including isonicotinamide, butyl paraben, dicyandiamide, and salicylic acid. Based on the same criterion for the nucleation point, the interfacial energy and pre-exponential factor are determined using the conventional linear regression method from the cumulative distributions of the induction time data for the same systems. The results indicate that the interfacial energy and pre-exponential factor calculated from the MSZW data are consistent with those calculated from the induction time for the studied systems.
本文应用基于经典成核理论的线性积分模型，通过对文献中报道的一些体系（包括异烟酸、对羟基苯甲酸丁酯、双氰胺和水杨酸）的亚稳区宽度（MSZW）数据的累积分布进行线性拟合，来确定界面能和指前因子。基于成核点的相同判据，通过对相同体系的诱导时间数据的累积分布进行传统的线性回归，来确定界面能和指前因子。结果表明，从 MSZW 数据计算得到的界面能和指前因子与从诱导时间数据计算得到的界面能和指前因子一致。
