摘　　要：根据普遍法的对应状态原理,建立了预测多元混和物的过热极 限温度的理论方法。用此法预测了6种二元混和物的过热极限温度, 理论值与实验值及动力学理论预测值都符合很好。The equating nucleation temperature for binary mixtures was established by the generalized state principle. Using the method, we predict the limits of super heat n-pentane-hex-ane, n-hexane-cyclohexane, Benzene-n-hexane, Benzene-cyclohezane, n-propunol-n-butanol, n-butanol-n-pentanol, six system of binary mixtures. Results showed that it is possible to predict super heat limits to well within the accuracy of measured values( < 1. 7% ) and the limit of super heat by the homogeneous nucleation theory ( 1. 2% ).
