作者用快速膨胀室测量了甲苯的均质成核速率随温度和过饱和度的变化。在215-267 K的温度范围内，测得的成核速率为102 - 105滴/cm ~ 3·s。测量结果与“经典”成核理论和RKC理论进行了比较。RKC置换因子的加入使数据与使用表面张力和粘附系数的物理现实值的理论非常一致。一个经验曲线拟合的数据，以及用于计算的热力学常数的完整列表。
The authors have used a fast expansion chamber to measure the homogeneous nucleation rate of toluene as a function of temperature and supersaturation. The measured nucleation rate ranges from 102 to 105 drops/cm3 s over a temperature range of 215–267 K. The measurements are compared with the ‘‘classical’’ nucleation theory and with the RKC theory. The inclusion of the RKC replacement factor brings the data into good agreement with theory using physically realistic values of the surface tension and the sticking coefficient. An empirical curve fit to the data is presented as well as a full listing of the thermodynamic constants used for the calculations.
