实验研究了氩气中三种过饱和醇蒸气的均形核。一种气体动力激波管方法用于使蒸气经受短的过饱和脉冲。用米氏光散射法测定生长核的数量和大小。结果表明，当成核速率为108 cm−3 s−1时，在很宽的温度范围内存在过饱和度。与经典成核理论（CNT）的比较表明，随着温度的降低，分歧越来越大。
The homogeneous nucleation of three supersaturated alcohol vapors carried in argon is investigated experimentally. A gasdynamic shock tube method serves to subject the vapors to short supersaturation pulses. The growing nuclei are detected in number and size by Mie‐light scattering. The results provide the supersaturation over a wide range of temperature for the nucleation rate of 108 cm−3 s−1. Comparison with the classical nucleation theory (CNT) exhibits increasing divergence with decreasing temperature.
